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.
