Gaining Insights into Children's Geometric Knowledge
Mack, Nancy K.
Teaching Children Mathematics, v14 n4 p238-245 Nov 2007
This article describes how research on children's geometric thinking was used in conjunction with the picture book "The Greedy Triangle" to gain valuable insights into children's prior geometric knowledge of polygons. Exercises focused on the names, visual appearance, and properties of polygons, as well as real-world connections for each, are described. (Contains 6 figures.)
