Use this power point all year to review addition equations to twenty. The ten frames and equations will help encourage students to talk about addends, multiple addends, symbols, equations, sums, numbers and more. The equations will help students visualize the commutative property of addition. Younger students can begin to see what happens when an equation has multiple addends and how a number can change positions in an addition equation. I use this power point almost every morning on my SmartBoard as a math warm up activity.
