This product includes 8 task cards that cover 8th grade Geometry standards. These task cards have working QR codes that provide students with the answer card when scanned. The answer cards can also be printed out and provided to students.
PLEASE NOTE: When you print these, make sure your printer is set to landscape. Some printers do this automatically, but some are always set to portrait which will cause the cards to be printed smaller in order to fit vertically on the page. (This happened to me when I sent them to the printer at my school–it was a little surprising, but didn't really affect how I was going to use them.)
I use these task cards by printing and laminating multiple copies of each question card, as well as a couple copies of the answer key cards. Every student in my class gets a card to work on individually for five minutes. After that, each student meets in a group with the others who have their same card and they discuss the answer, as well as review the answer card to see the reasoning provided. In this way, each students becomes the "master" of one problem. After this we do some kind of activity (usually a practice train) where cards are traded so everyone gets the opportunity to do each card. When necessary, students can ask the "master" of the card how to solve the problem if they get stuck. I also let students check the answer after a certain amount of time, either using their phone's QR reader or by reading the printed answer card.
My 8th graders LOVE these cards. I've had way more buy-in with the kids who are more uncertain and don't like to show much effort for fear of being incorrect in front of their peers. This also provides them with a way to be social with each other (and not just their friends), as they interact with different people throughout the activity.
