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: To give students multiple and varied opportunities to create shapes, identify their attributes, and sort them based on their attributes.

Materials:

1. Dot Shapes
2. Dot Shape – Rectangle
3. Dot Shape - Circle
4. Dot Shape – Square
5. Dot Shape - Triangle
6. Stickers
7. Q-tips
8. Paint (finger paint, tempera)
9. Foam brushes
10. Dot Number Cubes (optional)

Activity:
Provide students with a copy of one dot shape and materials to make the shape.

1. Students could use stickers to put on each dot. This allows one-to-one correspondence practice as well as an opportunity to count the corners of some shapes or count the number of dots.
2. Students could also use a Q-tip or foam brush and paint to put a dot on each dot or to draw the sides of each shape.
3. Students could also use finger paint to touch each dot or draw a line on each side.
4. Student shapes could be sorted by attribute during another lesson or assembled into a book or bulletin board.
5. If desired, distribute dot number cubes to the student and have them match the dot configuration to the number of dots on their shape

Guiding Questions:

1. How many sides does your shape have?
2. Tell me about your shape.
3. Can you put a sticker, dot, etc. on each corner?
4. Can you paint a line on the sides?
5. Do you know the name of your shape?
6. How is your shape like that of your neighbor?
7. How is your shape different from that of your neighbor?
