Teacher Notes:

“Naming shapes is important, but even more important is observing the attributes, or characteristics, of shapes.

Characteristics of two-dimensional shapes that children might explore include

·          the number of sides and vertices (corners), and

·         how shapes can be put together or taken apart to make other shapes.” 1
