The book has a fairy tale theme and the names in the book are all math related. Sir Conference has changed into a dragon and Radius has to try and solve a riddle to change him back. I would recommend this book to ages 3 and up. My college math teacher brought this in one time, so it works for all ages! ( ) In my opinion "Sir Cumference and the First Round Table" is a great book to introduce circumference in a math lesson. First, the language is mathematical but also tells a great tale about camelot. "It has two long sides and two short sides. If you cut it in half, and put the two halves side-by-side, you will have a table with four equal sides." While there is math involved they are also telling a story about a new table in Camelot. Second, the illustrations enhance the students understanding about math but also the tale being told in Camelot. For example, when the table is being cut they show the dimensions but also showed the finished product. The big idea of this story is for students to understand what circumference entails. I enjoyed this book for a few different reasons. The first reason I enjoy this book is because of the use of math terms as the names of the characters in their book. For example some of the names are Radius, Sir Cumference, Lady Di of Ameter, and Geo. The second reason I liked this book is because the problem in this book requires a solution, and the solution is titled The Circle's Measure. It is a riddle that is actually a math equation. The main idea in this book is to learn things about math and making it interesting. One of King Arthur's knights is turned into a dragon and the knight's son must find the right potion and proportion to turn his father back to human, before the dragon is killed. This children's book for grades 2-5 explains the relationship between the number pi (3.14159...), the diameter of a circle, and it's circumference. While the writing is find, the math is find, and the illustrations are okay, I did not care for this book. There are many other facts about pi that could have been introduced. Unlike Sir Cumference and the First Round Table, the illustrations are just there but not especially helpful at clarifying the relationship. This book is another one in a series that uses a fictional story to explain a mathematical concept. In this story a man drinks a potion to alleviate his heartburn only to realize he is turned into a dragon. His only hope is his son who has to find the answer to a riddle to save his father. The answer to the riddle ends up being the number pi. As a teacher, I would use this book as a way to develop the students conceptual understanding of the number pi as the ratio between the circumference and diameter. I would use this book to introduce the concept and then stop once we arrived at the challenge on the circle's measure. At this point, I would have my students measure the circumference and diameter of various objects and find the ratio of the two quantities. After realizing the ratio is constant and the number pi, I would finish the lesson with the book. Once again, the pictures are a wonderful addition to the story. no reviews | add a review
