Self-checking task cards to practice area and perimeter of complex figures. Great for early finishers! Students can check their own answers using the QR Codes on each card. Twelve task cards total. Includes some slightly more challenging problems.
In order to use QR codes, you must have device with QR scanning capabilities. (free apps available) Great for iPad!
I also provided a paper answer key in case of technical difficulty or if you prefer to use it without the QR codes.
Printable sheet where students can record their answers and show work.
