This product gives students practice using formulas for finding the area of parallelograms and trapezoids. The file contain 8 different problems, with the answer to one problem being on the top of a different card. Therefore, students can begin with any problema and find the area of that figure. Then, they find the card with the matching answer and solve that problem. Once students reach the card they began with, they are finished.
This file contains two copies of the same question cards. Pages 2-5 include the answer in numerical form, pages 6-9 include the answer in a QR code form.
Note: You must have a QR code reader (i.e. smartphone, iPod touch, iPad, etc.) to use this part of the product.
