I thought this was an excellent book. It teaches the math concept of negative numbers, but at the same time teaches about earning money for the things that we want to buy, fiscal responsibility and the consequences of making bad choices. I love reading books like this to our girls. If they can learn these lessons now, they could possibly save themselves from a lifetime of crushing credit card debt and bad money management. I won't go so far as to say that this book does it all, but it is a very ...more

This book could be used with third or fourth graders to introduce how to use money, how you can have less than zero and also how you can use bar graphs to track data. I could see using this book and allowing students to try a project like this on their own as they investigate how you can save money and also how you can have negative or less than zero as you spend or use what you don't have. I think this book would be fun to use to scaffold into a class project where students get to try this on t ...more

Perry the penguin learns about negative numbers in this informational book. Perry realizes that all his friends have an ice scooter but him. His father says he needs 9 clams before he is able to purchase his scooter. After earning four clams from his mother for trimming ice, Fuzzy asks him if he wants to go to the Ice circus. Only he needs five clams so Fuzzy lets him borrow one. To keep track of his clams he graphs the number he has or loses everyday. However, Perry isn’t having a very easy tim ...more

This is a book I thoroughly enjoyed for the fact that ie helps to show a very effective way of keeping track of money with a graph and updating it day by day and creating a very healthy economical habit. The illustrations of the book were very bright and colorful for being place in what seems to be like the arctic because we can see that there is always snow or ice on the ground and the main character happens to be a penguin. I would use this book for the 3rd graders and up because of the teachi ...more

This book is about Perry the Penguin. He needs nine clams to buy an ice scooter, but he’s not very good at saving. Perry learned how to earn, spend, find, lose, and borrow clams on a simple line graph. I think this book would be fun to use in a class project where students get to try this on their own.

A pretty clever way to introduce kids to negative numbers!

Perry the Penguin tries to save money for a scooter and keeps track of what he has earned on a graph. The problem is he has to borrow money when he wants other things on his path to saving. He also learns that it isn't really fun to owe other people money- if you want to take the lesson that way.

Well done, Stuart!

I read this book to my classmates at NSU on Zoom. It was a fun read about a penguin who learns a lesson on how to prioritize and manage his money. The concept is learning about negative numbers and using a graph. In this picture book, third graders are the target audience.

Good book for introducing negative numbers to 3rd graders. Quite story about a penguin and saving his clams! Great suggestion for using a line graph.
Tasasha Battle
This story is about a penguin named Perry. Everyone at school has the new ice shooter but Perry. The new scooter costs nine clams and Perry has zero. So he does chores, work and search for enough clams to get the scooter. As he collects and loses clams Perry charts his progression. He creates a weekly dot chart to record his clams. The ultimate goal is to get enough clams for the scooter. On the other hand, just as easy as it is for Perry to get clams it is just as easy to lose them. Perry would ...more

This children's book is about a penguin named Perry who must save up enough clams (money) to buy a new scooter. Throughout the story Perry learns more about money management by keeping track of his spending and savings. This story would be a wonderful addition to any primary classroom setting and a great introduction to adding and subtraction. This book is also great for kids, parents, and teachers because it has additional activities students can do while they follow along in the book or do sep ...more

I really found this book as a discovery for myself. It is great for 3rd graders, which incorporates number sense (negative numbers). Students can have a clear understanding about negative numbers. The number line in front of students, while I would read this book can bring a clear explanation about negative numbers. The students can track Perry's(penguin) clams in the story by using a button or penny. The students would move the button/penny based on what is happening in the story. This story ca ...more

I loved this book. It's great for 3rd grade and incorporates number sense (negative numbers) and graphing. Students can have a number line in front of them while the teacher is reading.

The students would move the button/penny based on what is happening in the story, and the teacher would check for understanding

I really liked the story that went along with the lesson. The illustrations were interesting and kept me intrigued to finish the book. I really liked the graphs that showed his progress and his loss, it helped to visualize the problems better.

This was better than Divide and Ride and did a good job demonstrating the concept of negative numbers although the kids still didn't think it was a fabulous book.

This book talks about how a simple line graph can demonstrate the concept of negative numbers in a kid freindly way.

I learned that buying fun stuff can be a wast of money.

Less than zero introduces negative and positive numbers as Perry the Penguin buys things. I would use this to talk about addition and subtraction, and negative and positive numbers.

I was one of those kids who talked all the time in class. I loved telling stories. One day in the 4th Grade, my teacher said, “You tell such good stories, maybe you should try writing some of them down.” “Wow,” I thought. “She thinks my stories are good.” That’s when I started to really enjoy
