Shapes and Designs was created to help students to:
Understand some important properties of polygons and recognize polygonal shapes both in and out of the classroom;
Investigate the symmetries of a shape-rotational or reflectional;
Estimate the size of any angle using reference to a right angle and other benchmark angles;
Use an angle ruler for making more accurate angle measurements;
Explore parallel lines and angles created by lines intersecting parallel lines;
Find patterns that help determine angle sums of polygons;
Determine which polygons fit together to cover a flat surface and why;
Explain the property of triangles that makes them useful as a stable structure for building;
Reason about and solve problems involving shapes.
