Sir Cumference and the First Round Table: A Math Adventure

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 re-create 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 Standard
    Benchmarks (K-2)
    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 two-dimensional figures and three-dimensional objects according to their characteristics and properties.
    Grade Level Indicators (K)
    1. Identify and sort two-dimensional shapes and three-dimensional objects. For example: a. Identify and describe two-dimensional figures and three-dimensional objects from the environment using the child's own vocabulary. b. Sort shapes and objects into groups based on student-defined categories. c. Select all shapes or objects of one type from a group. d. Build two-dimensional figures using paper shapes or tangrams; build simple three-dimensional objects using blocks.
    Grade Level Indicators (1)
    1. Identify, compare, and sort two-dimensional 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 two-dimensional 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 (pre-K)
    3. Identify, name, create and describe common two-dimensional shapes in the environment and play situations (e.g., circles, triangles, rectangles, and squares).
