Unit: K.9

A Closer Look at Shapes

In this unit students

•  classify, analyze, and compare two- and three-dimensional shapes;
•  use simple shapes to compose more complex shapes.

In the last unit students circle back to work with shapes, looking more deeply at these geometric structures. This includes understanding the difference between two- and three-dimensional shapes. In Unit K.3, students learned to identify and describe simple shapes. In this unit, they deepen their understanding by analyzing and comparing different attributes of those shapes, describing similarities and differences. Students model real world shapes by building and drawing them. They form larger, more complex shapes using simple shapes. Providing concrete experiences for children in Kindergarten is important, as work with shapes in later grades will prove to be more abstract.
