Step 6: Instruct students to use the toothpicks to create and glue their model of each
two-dimensional figure in the appropriate cell on their construction paper.
Step 7: Have students use the small sticky tabs to cover the names of the titles for each
tooth pick model.
Step 8: Have students take turns with their partners identifying each geometrical figure
on the construction paper. Note: Challenge students to name the figures as fast as
possible.
