1. Textbook Instructions Activity 1 Plane Figures

Explain about the 6 types of plane figures. Learn the names of pattern blocks.
Tell students the names of plane figures.
The green pattern block is called a triangle. 1 Connect the dots to draw the figure. Write the name of each
The red pattern block is called a trapezoid.
The yellow pattern block is called a figure.

1. Have students memorize the names of
shapes while drawing them.

Students sometimes connect the dots with

connected,as illustrated by the diagram
below.
