Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by building a rectangle from a set number of cubes. Problems B through E maintain the same problem situation but increase the rigor by incorporating different shapes and more advanced concepts such as maximum area and constructions.

Instructional Ideas

• Provide manipulatives for your classes to use as they explore the different shapes
• Assign problems above- and below- grade level to differentiate when necessary

Classroom Considerations

• Expects a functional understanding of area and perimeter of different shapes depending on the level of the problem

Pros

• Includes a teacher guide with lesson descriptions and explanations
• Provides a handout for pupil reference

Cons

• None
