# Section A: Practice Problems Exploring Shapes in Our Environment

## Section Summary

Details

In this section, we noticed shapes in the world around us.

We described and compared shapes.

This shape looks like a door that is crooked.
It has 4 corners.

This shape has 2 long sides and 1 shorter side.

The shapes are different because one has 4 sides and one has 3 sides.

We learned the names of these shapes:

circle

triangle

rectangle
