Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean Theorem to determine the length of the diagonal of the block.

Instructional Ideas

• Provide opportunities to find perimeters of complex figures that require using the Pythagorean Theorem
• Group class members that used the same technique to find the perimeter and allow them to work as a group to arrive at a different solution

Classroom Considerations

• The class should be familiar with working with square roots

Pros

• The resource has an explanation of potential solution paths
• Includes a list of what a sample of eighth graders were able to do and not do when completing the task

Cons

• The rubric contains dimensions within the scores
