Travel to the land of King Arthur and experience the problem solving techniques of his knight Sir Cumference. Dissatisfied with the shape of his long table, King Arthur searches for a new design. Assisted by his wife, Di of Ameter, and his son, Radius, the knight Sir Cumference eventually finds the perfect shape, a circle. As it captures the imagination of your young children, this fun tale of knights and bravery will also give them a basic understanding of circles and geometric properties of other shapes as well. My young kids love to listen to it and even the older ones join in to hear it once in a while.
