Directions: Using the following squares, how many different rectangles can you make?
Hint
What are the properties of a rectangle?
Answer
Answers will vary depending on uniqueness. Answers based on uniqueness are: 1×12, 2×6, 3×4, 4×3, 6×2, and 12×1. How does adding 4 more squares change the problem?

I like this question, but consider making the instructions say “using ALL of the following squares” otherwise kids may produce a 1×2 rectangle, etc.
