Join Sir Cumference, Lady Di of Ameter, and their son Radius for wordplay, puns, and problem solving in this geometry-packed math adventure. King Arthur was a good ruler, but now he needs a good ruler. What would you do if the neighboring kingdom were threatening war? Naturally, you'd call your strongest and bravest knights together to come up with a solution. But when your conference table causes more problems than the threat of your enemy, you need expert help. Enter Sir Cumference, his wife Lady Di of Ameter, and their son Radius. With the help of the carpenter, Geo of Metry, this sharp-minded team designs the perfect table conducive to discussing the perfect plan for peace. The first in Sir Cumference series, Sir Cumference and the First Round Table makes math fun and accessible for everyone. Review: This whole series is great. - I bought the whole set to read with our grandchildren, ages 4 and 7. Now the 7--year-old is reading it on his own as well and seems to get these intriguing ideas behind numbers, shapes, dimensions, angles, and degrees. The series is written by an ingenious math teacher with a talent for weaving basic concepts into clever stories about "Sir Cumference," "Lady Di (of) Ameter," their son "Radius" and a host of similar Camelot characters. The illustrations are rich and fun. At first our 4-year-old was afraid to overhear about dangerous castles, scrappy knights, and dragons (which is strange, since she's willing to follow her older brother into the world of "How to Train Your Dragon"), but by flipping through the pictures beforehand and sometimes previewing the happy ending, I'm able to get her to cuddle up and absorb. I'm sure much older kids would enjoy Sir Cumference, too, and learn a good deal from them. I can't imagine why any children's or K-5 school library would not have these wonderful books on its shelves. Review: Fun and more than I expected! - My 4 year olds love this book! It's a fun story and has a nice recap at the end that makes it easy for kids to remember diameter, circumference and radius. But, I was happily surprised to discover that the book covers much more than circles. In the early attempts at making a table all can fit around, they cover some pretty cool things: -- cutting a rectangle in 1/2 to make it a square -- cutting a square on the diagonal to make a parallelogram -- octagons -- ovals It was a great book, made better by the addition of these other cool shape concepts. The plot moves fast enough that it's not boring at all, and teaches math in a fun and memorable way.

Such a fun way to learn mathematical concepts!
I got this book for my 6yr old granddaughter who loves to read and reads way beyond her grade level. She was excited to get this book and she read it to me cover to cover. I got her 2 more books from the series, and she absolutely loves them! I think this series of books is a creative way to introduce mathematical concepts to young children.

Sir Cumference a Teaching Tool
I used this book as a teaching tool to end-of-year 4th-Grade students as an introduction to Circumference, Diameter, and Radius, something they will study more in depth in 5th Grade. I put the book on a document camera so students could see the larger-than-life illustrations while I read aloud the story. They loved it. I think any age students like to be read to and they are never too old for a picture book. More important: Anything that can help students remember concepts earns accolades from me! The book got its best review the next day as we were continuing our Math lessons. As students were recounting terminology, I found they were using elements of the book to do so. I heard: "The measurement across a circle is ... Lady Di of Ameter, Diameter." And, What is radius? "Oh yeah, their son, Radius, was about half as tall as his mom Di of Ameter, so the radius goes from one point on the circle to the center point." The only reason I don't give it a full 5 stars is that I thought it was a little lengthy to use as an aide to a lesson. It took more time than I wanted, but it probably was well worth the time.

Great review!
I bought this book to use in my practicum teaching. I was in a fifth grade classroom and they had just started their unit on 'Parts of a Circle'. My lesson was on a Monday following their introduction to the Unit on the previous Friday, so I wanted something easy and fun for them to follow along to. I scanned the pages and compiled them into a slideshow that I projected on the screen while I read aloud so the students could follow along. My Cooperating Teacher loved this book and the students loved the characters and story! I will carry this book on with me into my future classroom and will remember the lesson I taught to the students forever. ❤️

Buen contenido
Aparentemente es muy pequeño y muy infantil, pero la verdad es que el contenido es divertido e interesante para acercar las Matemáticas a los estudiantes.

Wonderful book series
We absolutely love the Sir Cumference series. My 7 year old is getting immersed in math playfully and my 10 yo. Is revisiting the math concepts learned through a fun story. Very entertaining and enriching.
