2nd Grade Math 3.3, Make a Ten to Add

We can use the strategy (plan) make a ten to help us find sums. We break apart the lesser addend to make a 10. Then we add 10 plus the remaining part of the addend. We show many ways to make a 10. We can add in any order and get the same sum. We can see a pattern in number sentences whose sums are all 10. The first addend increases by one, the second addend decreases by 1 (and 5 + 5 = 10 is a doubles fact). We solve several addition sentences by making tens to add. We solve 3 word problems that involve making a 10 to add.
