Materials Preparation

Find a Shape Book. Find a book that depicts shapes in the real world to read with students to introduce the lesson. See the Literature Connections section for suggested titles.

Prepare Shape Charts. Make one chart each of the following shapes: rectangles, squares, rhombuses, triangles, hexagons, circles, and trapezoids. On each chart, draw several examples so that students see a variety of shapes within each category. Make the examples illustrate a variety of orientations and dimensions. Outline the shapes but do not color in the shapes. Leave room on the chart paper to post students' shapes. Put the charts up in different parts of the room so that students can form groups and discuss shapes near the charts. See Figure 1.


Figure 1: Examples of Shape Charts

Gather a Collection of Shapes. Gather objects that have circular, triangular, and rectangular sides. Include objects with different dimensions so that students see a variety of shapes. See Figure 2 for some suggestions. Include the pattern block pieces.


Figure 2: Suggestions for shape collection

Gather Materials for Book of Shapes in a Learning Center. Gather paper, sources of pictures, scissors, crayons, and glue in a learning center. Ask students to make a Book of Shapes to provide targeted practice with identifying two-dimensional shapes.
