  1. Identify Polygons - Names of polygons by number of sides and angles - instruction and review, practice, and a quiz
  2. Minimal Convex Polygon Decomposition - This applet demonstrates the Algorithm of Minimal Convex Polygon Decomposition, by using a dynamic programming approach to the problem.
  3. Minimal Convex Polygon Decomposition Demo - An applet which will decompose a polygon into a minimal number of convex polygons
  4. Name that Polygon - Identify name of given polygon components - instruction and review, practice, and a quiz
  5. Pattern Blocks - This is a little program that lets you make geometrical patterns out of blocks. It's just like playing with wooden pattern blocks, but there is one big difference: a group command, which makes it much easier to build large patterns.
  6. Polygon Playground - Arrange designs with online movable polygons - hundreds of polygons to drag anywhere you want. Create a composite shape from other shapes.
  7. Separating Shapes - Shape decomposition exercises and possible solutions. [8 page worksheet]
  8. Shape Search - Problem sets and solutions for composing and decomposing simple geometric shapes [8 page worksheet]
  9. Shape Search - Exercises in which students can look for basic geometric shapes in complex real-world architectural forms [2 page worksheet]
  10. Shapes at Work - Purpose: To look for shapes in both the natural and designed world; to investigate the ways in which shapes can be used; to design and build structures using appropriate shapes
