Young Children's Developing Understanding of Geometric Shapes
February 1999, Volume 5, Issue 6, Page 353
This study analyzed young children's understanding of the geometric concepts of triangles and rectangles, and defined patterns in the development of this understanding from ages 3 through 6. An understanding of how young children perceive geometric concepts and of how these perceptions develop as the child both matures and receives systematic instruction is imperative if teachers are to improve early childhood geometry instruction.
