Adding on tens- By: Veronica

Learning Intention: we are learning to add tens to any numbers by counting in tens or adding tens together.
Success Criteria: I know I am successful when I can add tens together.

Problems:
1.40 carvings + 20 carvings =60carvings
I know that 4 tens + 2 tens =6 tens

2.37 bananas + 40 bananas =77 bananas
I know its 77 because 30+40= 70+7=77

3.6+4+2+7+8=27
I know its 27 because 6+4=10 and 8+2=10 so, 10+10=20, 10+10=20+7=27
