Prekindergarten: Unit PK.G.A.1-2, Identify and Describe Two-Dimensional Shapes (circles, triangles, rectangles; including a square which is a special rectangle)

Domain:Geometry
Unit/Cluster: Identify and describe two-dimensional shapes (circles, triangles, rectangles; including a square which is a special rectangle.)
Standard(s):
PK.G.A.1: Match like (congruent and similar) shapes.
PK.G.A.2: Group the shapes by attributes.

Purpose/Big Idea: Students will identify and describe two-dimensional shapes and match similar shapes when given various two-dimensional shapes. Students will also be able to explain the groupings made when sorting.

Materials:

1. Large plastic tub, sand table, or water table
2. Filler: pompoms, sand, tinted rice, dried pasta, etc
3. Attribute blocks
4. Tongs or scoops
5. Sorting mat

Activity:

1. Fill tub or sensory table with attribute blocks and filler.
2. Using tongs or scoops, students will find and retrieve blocks and place them in the correct section on the sorting mat.
3. Observe students and ask guiding questions

Guiding Questions:

1. Why did you put this shape here?
2. Tell me about what you found.
3. Why can’t you put this shape over here?
4. If I turn this picture like this, does it change the shape?

For observation:

1. Can students correctly match attribute blocks by shape regardless of color?
2. Which students are able to group shapes by different attributes (size of shape, name of shape, etc)?
