Only, when Radius brought medicine to his father, the medicine turned Sir Cumference into a dragon. The town tries to run for cover while Lady Di of Ameter and Radius try to find a potion to turn Sir Cumference back before he his slain in the morning. Radius finds a potion “The Circle’s Measure”, which ends up being the formula for finding circumference. After many calculations, Radius was able to determine how much of the potion his dad needed, in order to turn him back to normal. Sir Conference and the Dragon of Pi is a good way to introduce pi. 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. no reviews | add a review

Update: My son has been learning about Pi and the formula for finding the circumference of a circle for a few weeks. He failed the whole unit, and I'm glad I remembered this book. We read it together, and he was motivated to experiment with string and measuring tape on various circular objects around the house. He has this formula truly understood now instead of memorized, and on several enrichment practice exercises he performed perfectly. He owes it all to this book. ( )
