In this one we learn by using an orange, that one could half each orange slice and lay the sides together "heads to tails" to create a rectangle. When you do, this illustrates that half of the slices equal the length of the rectangle. In other words, the length of the rectangle is equal to half a circle's circumference. And the width of each slice equals the width of the rectangle. So, the radius of a circle is the same as the width of its corresponding rectangle. So, all of this is to say that ...more

Back in the days of Camelot, people knew geometry, but they learned it in adventures instead of textbooks. Per of Ameter played a game created by the Countess Areana in which they figured the outside edges and inner pieces of shapes made with the same size squares. Their skill at this game allowed them to solve several mysteries on the Isle of Immeter through a few escapes, as the island was protected by a sea dragon. Finally Per solved all the puzzles, and the sea dragon delivered a locked from ...more

Sir Conference and his fellow family and kingdom go on another math adventure. This time to lean about perimeter. In this book, not only does it give an example of what perimeter is from the very beginning of the book, mentioning the square game at the beginning (the teacher gets the inside, the student gets the outside, which is the perimeter) Then, in Per's dream, she needs to solve several mysteries that involve perimeter or circumference. There are hands on activity ideas included in the sto ...more

My kids (almost 7 yo ds & 4.5 yo dd) absolutely love this series with Sir Cumference. (I like it too) We have read the series twice in less than the past 24 hrs!! ds rated the series as a whole 9 stars out of 5 which says alot as he usually gives everything 3.

Who knew that geometry was so much fun!! Fun & easy learning about area & perimeter (inners & edges in this cute book. What's not to love with a sea serpent, a mysterious message, with clever participants with names like Per

In the picture book, "Sir Cumference and the Isle of Immeter", written by Cindy Neuschwander multiple cools things happen. The author deigns the book so that when Per and Immeter (the charchters) figure out area and perimeter they can name perimeter, perimeter because there names combined make that name. Also it is very good for math teachers since it teaches formula's in a fun, unusual way.

We love Sir Cumference and his world. This book tells about Sir Cumference's niece, Per, who is captivated by the secret of the Isle of Immeter and how they solve the mystery using math.

This series is never dull and the wordplay on mathematical terms all set in King Arthur's time is entertaining. My children love these books and request them again and again.

sir-cumfrence is a book where it shows you how to measure angles and how to count the pieces in them. It also shows you that there is an island banned from the owner (areana) there is also the owner of another island and his name is sir-cumfrence.

It just goes to show that figuring out the circumference and the radius will grant you your very own castle. Who knew?!

This book is a lot of fun, what with the word play and creating a fun adventure out of counting squares.

Another fun mathematics story. This one involves a serpent, a mystery, daring and measuring inside and outside of shapes. A great way to introduce a concept, and a lovely story too.

Recommends it for: parents reading with their children
We discovered these books about Sir Cumference on the "Tumblebooks" online audiobook site ( Our girls really enjoyed watching them read aloud. Although I think the math concepts regarding geometry are a little more difficult to understand for children in grades K-2, I think it was a valuable way to introduce the concepts. Because the story itself is fun, it makes the educational focus of the book less apparent and more appealing.

A teacher read this in a class I interned in and it was really unfortunate because she read another book in the series too. It was so clear the kids were all bored--staring off, falling asleep, the minutes going by painfully slow. This was a fourth grade class. Some of the stuff in there was way above their level, so the book doesn't even know who it's aimed for. I can't believe someone put this on an educational children's book list--it's written by a person who doesn't know how to write educat ...more

This is a good book for a read-aloud experience with students in grades 3 - 5. The book is engaging, and young learners will enjoy the mysterious adventure in the book as Per solves perimeters and areas of more complex figures that are key-shaped during his adventure. In addition, the concept of circles and finding the area and perimeter of circles are introduced in this book. This book is great for expanding young learners' math vocabulary, too.

Today i read this this and its so interesting. This book is about math. In this book young boy and girl have to find a key and they have to unlocked the door and they will win. They think they can't do that but they do. They try their best and they find the key. They went to their house and they tell the story which how did they found the key and how they win. Their parent so proud with them and they so happy of that.

In this installment of the Sir Cumference tales, Radius and his cousin Per head off to the Isle of Immeter to explore and review some basic measurement concepts all the while pursued by a sea monster. The book covers area and perimeter of rectangular shapes and derivation of the area of a circle. Good stuff.

Great story about the parts of a circle and how to find perimeter and area. Broken down into pieces that could be used for students to solve with out the formula and then using the formula.

This is a cute math story that uses elements from the stories of King Arthur to teach students about geometry. This book's focus is on area and perimeter. There is also a lot of multiplying going on in this book.

This one is an adventure that teaches about finding the area of circles and other objects as well as the perimeter (but not the circumference; see dragon of pi for that one).

This is another great book for vocabulary with a built in activity for the class. You could also talk about fractions and relationships between different shapes.

One of the better Sir Cumference stories. It's an adventure and a puzzle hunt, with the answers found by playing a game of insides (area) and outsides/edges (perimeter).

I loved the way these stories are told. They are a fun way to learn math and also tell it in another way that I have never thought before :)
