Addition becomes much simpler once scholars understand its properties. They examine the commutative property through five equation pairs. For each, the addends have been switched and scholars must fill one in. The next six problems give an equation and ask scholars to choose an addition fact with the same sum from three options. Debrief this worksheet by asking scholars what patterns they notice, introducing the commutative property if you haven't already. Encourage kids by explaining that this means they know two addition facts for every one they learn!
