I hope your students’ enjoy this activity!! It’s a great way for kids to work alone and self assess their knowledge. I have included 20 task cards. I have also included an answer sheet. You can print, cut and laminate each card so that you can reuse them. Students can work alone or in a group. After they complete their task cards, they can check their answers by using a QR reader from either their smart phone or IPAD. QR Reader Apps can be downloaded from the App Store. By purchasing this document, you have rights to use in your class. It may not be resold or posted online in any form.
