How much good can an honest business venture do the world? A venture headed by someone wanting only to provide a necessary commodity to buyers who currently pay way more for it than they should, and to provide it for the absolute minimum profit margin. You won't find many adults interested in running a business for less profit than the market allows, but a kid? You might find a kid like twelve-year-old Rufus Mayflower, with the brains and sincerity to pull it off without his own innocence being corrupted. When Kate MacKinstrey moves with her parents from suburban Connecticut to Cleveland, Ohio, she doesn't fit in with the other kids until she meets Rufus. He doesn't care that Kate is white and he's black, and Kate is impressed by his pragmatism, smarts, and friendly spirit. On a routine trip to the drugstore to pick up a few items for his mother, Rufus gets to talking with Kate about the exorbitant price of toothpaste. Seventy-nine cents a tube? That's more than forty times what the product is worth. Rufus insists he could make a tube's worth of toothpaste for a couple of cents. And that's when the TOOTHPASTE adventure starts.

To keep costs low, Rufus engineers his own toothpaste formula based on bicarbonate of soda, then fills empty recycled jars of baby food with it to store for use. He and Kate sell the product locally for three cents a jar, making a penny profit on each sale. Soon everyone in the neighborhood wants to buy, and other kids are needed to help package and deliver. No fancy name developed by marketers is needed; Rufus calls his product TOOTHPASTE, and the name sticks. When TOOTHPASTE hits the airwaves via a local interest television program, "The Joe Smiley Show", business booms. People in Cleveland and beyond order TOOTHPASTE faster than Rufus, Kate, and their friends can pack it, and Kate figures it's time to expand the operation. With her vision of what TOOTHPASTE can become, and Rufus's earnest dedication to low-cost customer service, profits roll in, and TOOTHPASTE turns into a national sensation. Full-time employees are hired, factories rented, a coast-to-coast advertising campaign begun, but as controlling owner of the company, Rufus never diverges from the principles that made TOOTHPASTE successful. There are less scrupulous individuals than he in the dental hygiene business, however, men who will stop at nothing to buy out effective competitors or crush them to dust. But they don't have Rufus's winning attitude and honesty, and that's why no roadblock can permanently stop him. If you provide a quality product for minimal cost and don't stray from that model, the world is your bull market.

Rufus and his employees face some discrimination during his rise to business stardom. Rufus is black, but he's also a kid, and the adults who dominate the business landscape don't want to give him the time of day. As TOOTHPASTE grows in popularity, eventually it's necessary to take out a loan for factory equipment and other essentials, but banks won't front money to a twelve-year-old, not even a whiz kid with a solid business model. As The Toothpaste Millionaire bemoans, "The trouble with adults is that they never believe kids can do something even when they have good ideas." How are kids to achieve in any transcendent way when adults presume they're incapable of doing so because they aren't full-grown, so they refuse to support them? It's a self-fulfilling prophecy that prevents kids from reaching their potential until they're old enough that adults take them seriously. It's a significant barrier for Rufus, but a kid with the foresight to maximize profits by minimizing them is clever enough to obtain startup capital to get his business moving in the right direction. After that, watching the show grow is pure fun for the reader, who knew Rufus could tame his challenges all along.

Thirty-five years after The Toothpaste Millionaire first entered print in 1972, Gary Paulsen released Lawn Boy, a more popular book that explores the idea of a kid becoming wealthy after his neighborhood business performs absurdly well. As much as I love Gary Paulsen, The Toothpaste Millionaire is the better story, though. Lawn Boy's success falls into his lap, mostly owing to dumb luck. Rufus thrives because he crafts his ideas carefully and has a kind heart, never prioritizing profit over people. His ascent to fame and fortune is more believable, and the way he overcomes adversity shows why he's a winner in the business world: it's not in spite of his youth and inexperience, but because of them. That's why I rate The Toothpaste Millionaire two and a half stars, a full star higher than Lawn Boy. Author Jean Merrill has a bit of Newbery Medalist Susan Patron in her style, and I like it. If you pull for good kids to flourish in a world biased toward adults, you should kick back with a copy of The Toothpaste Millionaire and enjoy the ride.

A young Black American boy with the entrepreneurial skills of Madame CJ Walker and the curiosity and ingenuity of George Washington Carver brings his classmates from different backgrounds together to create something better and more cost effective than what already exists in 1960's Cleveland, Ohio.

Inspired by his like minded, industrious grandmother - Rufus Mayflower, a boy outraged by the high cost of toothpaste - designs a product for less than 20% of the cost of existing brands.

To me this story embodies hope. Hope that there exists people like Rufus who see a problem and want to fix it - not to make millions, or to make themselves look good - but to make others' lives easier. Rufus had a business model that shouldn't work in theory. He created a cheap product that lasts for a really long time so customers don't have to replenish their supply of toothpaste as frequently and thus save more money in addition to what they already save for a cheaper product. But it worked! If Rufus charged what the other brands charged, he could have easily been a billionaire. But he wasn't greedy, he did not prioritize money and he still profotted handsomely with a sum that likely went much farther in the 1960's than it would in 2018.

Rufus is the possibility that there exist people who strive to provide what others need without extorting them for high profit margins. Rufus is the possibility that there exist people who can enter a position of power and not be corrupted by others in the same league.

Rufus is more of what this world needs.

As part of UMHB's READ 3307, I read The Toothpaste Millionaire. This is a fun and educational story that will catch older readers attention and help them gain interest in new topics like economics and inventions. The story follows Kate, a 6th grader and her friend Rufus, who is a genius. Rufus has formulated a type of toothpaste because he is outraged at the cost of the toothpaste available in stores. The book is about how he markets and sells his toothpaste and the expansion of his business which he runs by himself with the help of some of his friends. Though it's certainly not typical for a middle schooler to start their own company, it is certainly possible, which is why this book can be classified as contemporary realistic fiction. This book challenges children to think outside the box and achieve more than what is normally expected of them. The theme of setting high personal goals is increasingly relevant because children need to learn to be self motivators if they are to be successful. In the story, Rufus builds his business up with very little adult influence and it was entirely his own idea. His company starts small but you'll have to read the story to find out just how big it gets!

What a fun, yet educational idea, for a kid’s book! It’s a story that walks you through the process of starting and running a business!

Rufus is an imaginative boy with a lot of initiative, good math skills and spunk. When he decides that he can make toothpaste for a lot cheaper than is being sold at the stores and that by selling it at only one cent over cost he can make 2.5 million in a year, he sets out to prove that very idea! Luckily he has Kate and Hector and a few other friends to help out!

I liked how much math and business sense got incorporated into the story! It was pretty realistic, even the ending where the FBI gets involved because the stock certificates don’t look real, legal advice wasn’t sought, and because some competitors were attempting to price fix the product. Made me laugh and also roll my eyes at the same time!

I thought the bombing at the end was weird - and that Rufus and Kate were grateful to the bomber (even visited him in prison a few times) for not bombing the factory while they were in the building. That entire story thread was odd. Also the several incidents of discrimination against Blacks seemed contrived and not relevant to the story. Lastly, there were a number of comments that indicated the main characters thought making more than you need is a negative and too much of a profit is terrible. I understand and appreciate not gouging people, but there wasn’t enough clarity on this point to satisfy my capitalist heart.

Ages: 8 - 12

Cleanliness: a girl thinks her brother is boring and kind of annoying - a number of comments but nothing too extreme. A number of comments about discrimination between blacks and whites - the relationships in this book are healthy but the topic gets brought up a couple of times. A girl says that adults are annoying because they don’t think kids are capable of anything - she slightly retracts her comment.

This is the story of my friend Rufus Mayflower and how he got to be a millionaire. With a little help from me. With a lot of help from me, as a matter of fact. But the idea was Rufus’s.

Who would pay $.79 for a tube of toothpaste? Why, it was so outrageous that 12-year-old Rufus Mayflower takes matters into his own hands and sets out to make his own toothpaste for less…much, MUCH less. Drawing from his days at his grandmother’s house, Rufus concocts a toothpaste recipe and proves that he can, in fact, make a whole gallon of toothpaste for the same cost as a single tube. Excited to pass on this cost savings to consumers, he partners with his friend Kate and soon earns the attention of a local TV personality. Rufus’s toothpaste not only gets noticed by the public, but also by some of toothpaste’s biggest manufacturers. However, what Rufus learns about business and competition is nothing to smile about.

Set in the 1960s, Jean Merrill’s The Toothpaste Millionaire is a testament to ingenuity, entrepreneurship, and integrity. Fans of her classic David-versus-Goliath book The Pushcart War will once again be cheering for the underdog who takes on the establishment and proves that when the good guys win, they win big!

The heart of the story is the interracial friendship between Rufus and our narrator Kate. This relationship may not bat any eyes today, but during the story’s setting, it was considered uncommon and unconventional. But as fate would have it, a single and simple act of kindness opened the door to a friendship built on mutual trust, respect, and admiration. Merrill gives the story a nice twist by making Kate—who is white—the outsider, having moved into a predominantly black, middle-class neighborhood. As she also serves as the story’s narrator, she describes first-hand what it feels like to be excluded and viewed suspiciously. However, racial lines are soon blurred as everyone comes together behind Rufus’s lucrative and ambitious venture.

The Toothpaste Millionaire is an ode to the self-starters who feel that something could be made cheaper, faster, better, or smaller. Merrill somehow makes learning economics, math, and marketing fun through a cast of likeable characters, a fast-paced story, and the idea that treating people with fairness, kindness, and respect bears its own riches and rewards.

Two sixth-grade friends start a toothpaste business. Business concepts, as well as math, are incorporated into the story.

But some very important math is left out of the book. To earn "a little over $2 million" of profits in one year at the rate of one cent per tube of toothpaste, Rufus and his friends would have had to manufacture and sell more than 3,500 tubes of toothpaste each week. This is supposed to be realistic fiction and that production rate doesn't seem possible to me. At the start, Rufus's helpers are a handful of other sixth graders. Even when his operation grows, he has one full-time employee with an outdated machine. Since they are selling a year's worth of toothpaste at a time, the 3,500 purchases each week would have to be new customers. This is quite a difficult proposition given that "the only TV advertising we could afford was on local stations."

Still, there are some very important business principles and lessons taught through this story. If used in a classroom or book club, the group could start a business together alongside Rufus's toothpaste venture.

The inclusion of a movie script near the end of the story is confusing. It's not clear if those events are taking place or Kate is imagining them.

My edition the picture-book sized, 89 pp, Bank Street/HMH, 1972. Nice color illustrations, but still a true juvenile novel despite the odd shape. I'm reading it because the author's The Pushcart War is one of my all-time favorites.

Quick exciting read. I love how the math teacher, Mr. Conti, incorporated real life math from the toothpaste industry into class. I love that most people didn't care about race, but Merrill reminded us that it is relevant to some people. Much of the book is dated, but unfortunately I don't think the bits about racism are. And the history lesson about Grandma MayFlower's rejection of her slave name is valuable, and the bits about auctions & bureaucrats & bank loans, etc. are fascinating to the right audience.

And aren't most kids the right audience? Don't most kids dream of big money?

Sure, the story is unrealistic. But not entirely a fantasy, and I love it now and would have when I was a kid, too.

I learned a valuable lesson or two with this book. If I read it that was long ago because it's been around as long as I can remember. A 5/6th grade Math teacher asked for recommendations and since this book always comes up when searching for "math" fiction I decided I should investigate.

My copy is about 30 years old, and it is ugly. Who would want to read it? Well, I did and the book is valuable! If you haven't read it, do so. There is a good reason this book is still included in many Opening Day Collection lists.

I'm getting a new copy and certainly sharing this book often. It contains a great social message, lots of real-world and effective Math, AND it is a good story! I really think kids would enjoy it.

Go find a copy, and more importantly don't cut this title from your collections!

Wonderful, engaging read.

This 89-page book is probably confusing to those in marketing. The 22 chapters are very brief, but it's not a beginning chapter book. It's middle grade, although some of the topics may be more on the high school level - I think only advanced junior high kids would grasp some of the business concepts.

The voice is absolutely perfect - a sixth grade girl who is very bright (though not exceptionally so), very honest, and not very street-wise. The short paragraphs work really well here, which is not always the case. It reads a lot like a student essay, though a bit more informal.

There is some early 1970s social thinking that seems perhaps a bit too contrived - the girl is white, the boy is black and they think nothing of this, although it is explicitly stated that others do. But it's presented in such an appealing and humorous way that this does not feel like an "issues" book. I appreciated the little poke at women's lib ("Mr. Perkell says you have to have a woman on a Board of Directors these days.") and how the next sentence shoots that down.

The illustrations by Jan Palmer make me think of what Trina Schart Hyman would do if the wind weren't constantly blowing in her world. I think I must know Palmer from something else, but I'm not sure what right now.

I read this to my first grader and third grader. Though some of the math concepts were over their heads, others were adaptable to their level. Like many kids, my kids have wanted to "start a business." This book fleshed out some of the obstacles that might be encountered in setting up one's own business... as well as the problem-solving involved to move past those obstacles.

I brought it home from the library but my 8 yr old didn't want to read it because she said the title didn't sound interesting. I said I would start to read the story out loud and if she didn't want to continue I would read it to myself. By the end of chapter one she was hooked and kept saying "don't read ahead!" It was fascinating, believable, funny, great read aloud.

I loved that it had both black and white children, that it showed the usefulness of math, that being honest is admirable and can lead to more business. So many lessons in this short book. Really, really enjoyed it.

We read this for our homeschool entrepreneurship unit. It provided a quick representation of how a young person might start a business and some challenges he or she might face. Given that the book is geared towards middle elementary, I was surprised at how much my older students and I liked the story. One complaint I have is that towards the end, the storyline seemed rushed.

What an exciting story! Very simply told I think this story would inspire young readers to realize there are lots of possibilities available to them IF they just start putting the effort towards their dream. Being a millionaire is definitely a fantasy but being a success shouldn't be.

Below is my 9 year old son’s review (without any edits for grammar or spelling)

The novel toothpaste millionaire by Jean Merrill about a boy around my age is kind of inspiring because a boy like me could start a business without growing up. A boy named Rufus lived in cleveland ohio. he decided to start a business. the business was about toothpaste. he made that business to make money. will his business survive when they need a loan? I like this book because its inspiring and about making a business and i would recommend this to people who would want to make a business.

Rufus is the idea man and Kate is his friend who manages the production aspect of making toothpaste and together they put out enough toothpaste to put $1,000,000 in the bank. Along the way, a strong friendship is formed between two unlikely candidates: white, female Kate and black, male Rufus. Solid, entertaining read for those in grades 3-6, although the 3rd grade readers will need to stretch to handle the vocabulary, but its relatively short length will not intimidate any in the target age group. Themes of friendship and strong work ethic are clear but not in an "preachy" way. Highly recommended for literature circle/guided reading groups in ELA classes with no warnings on content needed.

Upset by the high cost of toothpaste, Rufus Mayflower, an enterprising sixth grader, decides to start making his own. Once consumers realize he is able to make a gallon of his homemade toothpaste for the cost of a single tube at the supermarket, business really takes off. As the demand for Rufus's toothpaste increases, he encounters a number of challenges, all of which he is able to solve with perseverance and ingenuity. The story is narrated by Rufus's friend, Kate, who, along with her classmates, solves math problems based on the growth of Rufus's business, modeling for readers how to calculate Rufus's costs, profits, etc.

This book is certainly a gift to anyone trying to teach a reluctant math learner. It shows exactly how math is used in practical ways in everyday business dealings, and it makes the math appealing by surrounding it with a compelling story. It also teaches kids how businesses are formed and how they run without bogging them down in a lot of details that sound boring or tedious.

But while this is one of the appealing aspects of the book, it's not the only one. This is not just a 90-page math problem. Rather, it is an engaging story, told by a believable and relatable narrator, Kate, who helps the reader develop feelings of awe and respect for Rufus and his capabilities. Because Kate does not have Rufus's knack for running a business, she has many of the same questions the reader might ask, and she is able to act as a bridge between Rufus's genius and the reader's own lack of sophistication. The story as a whole also empowers kids to think of themselves as innovators and creators and debunks the idea that only adults can make a difference.

Newer books have told stories with similar premises (Lawn Boy by Gary Paulsen, Frindle by Andrew Clements, The Lemonade War by Jacqueline Davies, etc.) but The Toothpaste Millionaire told it first and best, in my opinion. Another similar book, Henry Reed, Inc. (1958) by Keith Robertson, would also make a great read-alike for this book, but even Henry's research company in that story doesn't result in earning a million dollars! The Toothpaste Millionaire would make a great read-aloud for a wide range of ages; readers well beyond the age range of the intended middle grade audience can also get something out of it. I'll definitely be reading this book again with my kids in a few years!

This review also appears on my blog, Read-at-Home Mom.

This is a great little story about how an idea becomes a product becomes a business. As a child, I loved the idea that a kid could become a millionaire by creating something everyone used and then selling it at a reasonable price. As an adult, I enjoy the interactions between the characters. Rufus isn't too smart to take advice from his friend Kate, and through helping Rufus, Kate discovers a talent for writing. The technology is a little dated, and today's children may not be familiar with how race relations were in the 1970s, but it's still a good starting point for teaching children about economic basics.

A fun story about a boy who becomes a millionaire making toothpaste. I would give it 3.5 stars if I could. I think upper elementary kids will really enjoy it, and also middle grade reluctant readers. It will speak to any kid who has ever dreamed of starting a business and making big money. I really loved it until I got to the end, which I found a little awkward and confusing (one of the characters starts imagining the story as a movie script, and it's a bit confusing discerning what is really happening and what she is imagining for her movie script.) All in all, it's a good, solid choice!

I thought this was an adorable book about a smart boy and his friends. It is really a shocking tale of a great idea. I loved it, I even did a book report on it. The story of how I found it starts in my 4th grade elementary library. The library was having a book sale because they wanted to get more books. So When I saw it I just wanted to get it because I thought it would be cool. Boy did it go past my expectations!

I really enjoyed this one. It has many educational aspects without being a beat your head over it type of book. It deals with racism, sexism, math, stocks, accounting, and more all in a quick read. I read it on my own when I found myself bookless but I'll be sharing it with my kids very soon.

The Toothbrush Millionaire has been around since 1972/52 years old! I'm 58. I wonder if I read it when I was between 8 and 12?! I was a reader back then too.

I've rated it a 2/"it was ok" because I feel it wasn't necessarily written very well. I've read lots of kids books in recent years and I've read a lot of really great books and not so great books. Unfortunately, this is the later.

The story takes place in the 1960's when it wasn't so common for black and white people to mingle or to be best friends. Of course there were exceptions. Rufus is black and Kate is white and they are in 6th grade together. Rufus is really good of putting things together and has a knack of coming up with ideas for inventions and making things better, while Kate's strength is more the business side. Between the 2 they make a perfect pair for owning a business. And that's what happens.

Rufus' grandmother made her own toothpaste using baking soda. Rufus feels paying 79 cents for a tube of toothpaste is highway robbery which is a hoot because today it's basically $4-$6 for a tube. He knows he can make and sell it for 3 cents per tube (or in this case, jar) and still make a profit. As I'm reading the story more, the math really doesn't add up for him to become a millionaire on so little of a profit, or in such little of a time period or in paying a full time staff, renting the building, no mention of the costs of the expenses of water, lights, etc. I don't want to be a poo poo about it, but I guess that's the adult in me. The story is supposed and is, to be all in good fun and learning.

The story dealt with a lot of themes - sexism, racism, age discrimination, entrepreneurship, friendship, finance, and math. It's good to expose children to such real issues in life because as sad as it is, it's still the same today, all these years later.

I totally didn't get the need for the author to have a chapter of Kate thinking about the time when she's older and her choice of a "life career". The chapter was a movie script Kate had written. The script was.....boring, actually the whole story was kinda boring and it felt off and why I could only gave it a 2.

This was one of my late mother-in-law’s favorite books. She was an elementary school teacher and reading consultant, and when we helped box up her personal library, it seemed like every box had a copy of this book – paperbacks and lovely hardcover special editions in various states of use. Despite this, I had never read it, so it seemed like the perfect choice as a summer read-a-loud book with my eleven-year-old. He chose it over several other enticing options because it’s short and it turned out to be a zippy fun read that actually explains concepts like stock options, profit margins, and personal loans as well as doing a decent amount of math. The narrator is a Kate (McKinstry) Mac who moves to Cleveland in the 1970s. There, the first real friend she makes is Rufus whose brain is always going a mile a minute solving problems. They first meet when he helps Mac after her books spill across the road while she’s biking to school. She soon gets swept up into his plans for manufacturing affordable toothpaste at a fraction of the price that it’s sold for in the stores. Rufus has a creative and practical brain, while Mac’s is more impulsive, but they make for an unstoppable team that takes initial curiosity and turns it into a real movement, a business about plain speaking and honesty run mostly by kids. Sure, it’s a fantasy, and the end of the book takes a bit of a turn towards the dramatic, but it’s a great one. Kids who puzzle through real world problems and find solutions can really build things and make money? Sign me the hell up! This book also faces head-on the reality that Mac is white and Rufus is black. It isn’t dwelled on or turned into fireworks, but it’s real and something everyone notices and sometimes acknowledges. I appreciated this book for not pretending that discrimination wasn’t a problem, despite Rufus’s clear genius. I can tell why my mother-in-law returned to this book again and again. It’s clever and short, but also something you feel good about reading.

I previewed this as an elementary book to read at home for independent reading. Every kids wonders what it would be like to make a million bucks. An inventive, resourceful eighth grader in 1960s Cleveland finds out. The narrator is the new kid in town and, because she is a bit of a tomboy, she is finding it hard to make friends with the girls in her neighborhood. After she spills her books and papers all over the street, a fellow eighth grader helps her out. She asked where he bought his nylon bookbag, rare in those days. He told her how. When he saw her in math class, he slipped her a note with instructions of how to make the bag along with costs. Their teacher busted them by reading the note aloud. He was shocked to learn it really was a math problem. Imagine that. He invites her home and shows her how to make her bag and that was the beginning of a fast friendship. I will leave it to you to learn how he makes a million dollars.

The strengths of the book is the example of entrepreneurship and resourcefulness which many real life examples of math in action. Woven into the plot is an understanding of how to start and market a business. The weaknesses are that (1) nobody likes math (WHAT says this lover of math?) and (2) the author feels obligated to explain how two kids with different races could be friends. It would be better to let the friendship stand on its two feet without explanation.
