Motivate your students by having them scan QR codes! Cut and laminate the cards for durability. Place them around the classroom and have the kids hunt around the room to find them and first scan the black QR code. Make sure the volume is up, because scanning the code will ask your students a question about the faces, edges, and vertices of a solid shape. Your students will then write the shape (answers) on their answer sheet and then scan the little red QR code with their scanner to see if their answer is correct or not!
Please note that you need a smart phone or iPad that has a scanner or app on it already to use this file. I use Qrafter.
