Your students will LOVE doing this fun, simple QR code activity!
Students scan the QR codes you've placed around the room (included). The QR code gives them the addition fact to record on their sheet. They must then write the 2 subtraction facts that go along with the addition fact.
There are 4 problems, and 2 bonus problems! I've also included a "Write Math" problem that has students EXPLAIN WHY relating addition to subtraction can help them subtract.
Answer sheet included!
