Sir Cumference and the First Round Table: A Math Adventure Author: Cindy Neuschwander Illustrator: Wayne Geehan Publisher: Charlesbridge Publishing Copyright: 1997 ISBN: 1570911525 Number of Pages: 32 Ohio Standards Alignment: Grades preK–2
Inspired by King Arthur's Knights of the Round Table, this book tells the story of how one Knight, Sir Cumference, and his wife, Lady Di of Ameter, and their son Radius overcome seating issues for the Knights. Beginning with a long rectangle, they try tables shaped like a square, a parallelogram, a triangle, an octagon, and an oval, before settling on a round table as the best solution. King Arthur is so pleased with their work that he decrees that the circumference, diameter, and radius of a circle shall be so named in honor of his worthy subjects.

How to Use This Book

 This book would make a good beginning for children being introduced to circles and their parts.
 Students may be able to create various table shapes using construction paper and some "action figures" to recreate the situations in the book.
 I have used this book with middle grades and high school students, as a review of basic vocabulary for average students and as a memory jogger and motivation for advanced students.


Highlights and Insights

 Students know the names of shapes, but this book may help students see differences and similarities in the properties of shapes.
 It also starts students thinking about breaking up one shape and forming another shape from its parts.
 Communicating in mathematics using appropriate language is extremely important. This book gives students who have difficulty in this area a boost in an entertaining and creative manner.

Geometry and Spatial Sense StandardBenchmarks (K2) A. Describe and create plane figures: circle, rectangle, square, triangle, hexagon, trapezoid, parallelogram and rhombus, and identify them in the environment. C. Sort and compare twodimensional figures and threedimensional objects according to their characteristics and properties. Grade Level Indicators (K) 1. Identify and sort twodimensional shapes and threedimensional objects. For example:
a. Identify and describe twodimensional figures and threedimensional objects from the environment using the child's own vocabulary.
b. Sort shapes and objects into groups based on studentdefined categories.
c. Select all shapes or objects of one type from a group.
d. Build twodimensional figures using paper shapes or tangrams; build simple threedimensional objects using blocks. Grade Level Indicators (1) 1. Identify, compare, and sort twodimensional shapes; i.e., square, circle, ellipse, triangle, rectangle, rhombus, trapezoid, parallelogram, pentagon, and hexagon. For example:
a. Recognize and identify triangles and rhombuses independent of position, shape or size; and
b. Describe twodimensional shapes using attributes such as number of sides and number of vertices (corners, or angles). 2. Create new shapes by combining or cutting apart existing shapes. Grade Level Indicators (preK) 3. Identify, name, create and describe common twodimensional shapes in the environment and play situations (e.g., circles, triangles, rectangles, and squares).
