This book can be used to discuss geometry and shapes such as parrellelograms and triangles with students. ( )

This story is about brave knights and a strong ruler having a dilemma that needs to be solved by using math. This is useful in introducing geometry concepts. ( )

This is a great story for teaching children about the circumference and perimeter of a circle. I like this story for several reasons. I like the author’s use of language and his “play on words”. He uses math language to tell the story of how the first round table came about, and was used by King Arthur and his knights at Camelot. He names the most important knight: Sir Cumference, to represent “circumference, and his wife Lady Di, to represent “diameter”. Their son is named Radius. The author names the whole family after the parts of the circle. They work together to formulate the perfect table for the knights to sit at: a circular table. When measuring the fallen tree for the table, Lady Di stands tall and is able to stretch across the whole circular trunk. This represents the diameter. Her son Radius is half her height, hence the radius of the circle. I also like the use of pictures in this story. There are a variety of pictures included throughout the story, and help the reader visualize the problems with the different tables that are created. The diamond shaped table has sharp edges and ends up poking the kind in the stomach. The images also help the reader visualize what is being done to shape the table different ways using the same pieces of wood. In order to make a square table, you must cut it in half vertically and then align the two pieces on top of each other, creating a square with four equal sides. The moral of this story is to never give up. ( )

Great book using a modified version of Sir Author and the Round Table to introduce math concepts to children in a fun and entertaining way.
Classroom:
Great introduction to math concepts: shapes/parallelograms, circumference, radius, etc... This book may help reinforce these new concepts by being relatable in the story

I wish we'd learned mathematics with help from this series!  Effective, and fun too.  And the art is appropriately lively & clear as well. ( )
