Adding on tens- by Aleenah

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 its 60 beacause 4 tens + 2 tens= 6 tens.
2. 37 bananas + 40 bananas= 77 bananas
    I know its 77 because 30 + 40= 70 + 7= 77.
3. 15 + 5 + 10= 30
    I know its 30 because 15 + 5= 20 + 10= 30.
4. 6 + 4 + 2 + 7 + 8= 27
    I know its 27 because 6 + 4= 10 and 2 + 8= 10, so 10 + 10= 20 +     7= 27.
