This product includes 16 math addition problems with QR codes for students to self check their work. The problems start at 10+0 and go up to 10+15. These would be great to print, cut, and laminate for students to reuse again and again with a dry erase marker in a math center. They can then self check their work with a QR Code Reader on a device.
