Sir Cumference and All the King's Tens: A Math Adventure Paperback – Illustrated, July 1, 2009

This book was great, but maybe just a tad confusing. I used this in a lesson plan with 3rd graders. The story is sufficiently interesting, and it tells a story of place values up to the thousands place. This would be a good book to introduce a lesson on place values, or to close a lesson on place values. Just don't use it for the instructional part of your set or your kids will be a bit confused. Good book overall and I would use it again!

My 8 year old grandson enjoyed reading this book together.

My 5 year old really enjoys this book and others in the series. It was a great way to introduce him to the concept of place value and expanded number form.

My son (a kindergartener) loves these stories. Most of them tackle topics just beyond him, but this story, the round table, and the sword and the cone have been just right. He lights up when he solves the story's problem (and checking the answer at the end!) and loves hearing about the concepts at the end.

This book was cute and I enjoyed the way it pulled in the math. We've only read it a couple of times, but my 5 year old seems to enjoy it as well.

Pretty funny book. Bought this book for my daughter when she was 6. Two years later, she still enjoys reading it. She liked how it talks about place values and she can apply it to when she is at school or when she has to count quickly. I would recommend to others.

Great book! Fun way to illustrate place value. Cute story!

The Sir Cumference books are great for kids interested in math. My 8yo son, who loves math, devours these, though my 8yo daughter who is not interested in math, finds these uninteresting as well. But they teach concepts in a really great, fun way.
