Selected Homework from ACE

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.
