Adding on Ten -by Mo'onia

Learning Intention: W.A.L.T.- add tens to any number by counting in tens or adding ten together.
Success Criteria: I know I am successful when I can add tens together.

Problems:
1. 40 carvings + 20 carvings = 60 carvings
I know that 4 tens + 2 tens = 6 tens

2. 37 bananas + 40 bananas = 77
I know its 77 because 30 + 40 = 70 + 7 = 77

3. 15 + 5 10 = 30
I know its 30 because 15 + 5 = 20, 20 + 10 = 30

4. 6 + 4 + 2 + 7 + 8 = 27
I know its 27 because 6 + 4 =10 + 2 + 8 = 10 so, 10 + 10 = 20 + 7 = 27
