Sir Cumference and the First Round Table: A Math Adventure

Very clever - the story, the characters' names - all of it. Perfect for a grade school student! I bought it for my seven year old and it got a big thumbs up from both him and his dad.

Very cute story and a nice way of using word play to describe geometric vocabulary. Great for an introduction to the concept and as a review for older children.

This 32 page children's book tells how Sir Cumference, his wife the Lady Di of Ameter, and their son Radius solve the problems of the king's table. King Arthur and his knights needed to have a council, but there was a problem with the table around which they met. It began as too long; after that was fixed, the table had too few sides, and other tables produced more objections. Geo of Metry makes tables in several shapes before a round table solves all the problems. The illustrations are great, with medieval pageantry and geometric explanations. A few other characters from Camelot appear, such as Sir Lancelot and Sir Gawain.

This is a great book to introduce geometry to the young, making it fun and easy. Shapes and measurements are explained in the quest for the perfect council table for the king and his knights. When the round table is finally found to be the perfect shape, the king names certain measurements after Sir Cumference, Radius, and the Lady Di from Ameter. Very cute!

My kids (9 and 6) , who are homeschooled, loved this story and it resulted in them being able to instantly recall the proper names of geometric elements and classes (e.g., radius, circumference, obtuse, acute). This is probably due to the clever visual and contextual associations provided. We bought another book in the series right afterward with the same results. Plan to get them all.
