This is a fun cut and paste activity on the area of parallelograms, rectangles, and trapezoids. This resource is great for self assessing because students will look and see if their answer is on one of the puzzle pieces. If not, they know that they need to go back and check their answer. In addition, students are able to check their work when they are putting the puzzle pieces together.
This activity works best in groups of 2-4. You can print on regular paper or colored card stock.
