Adding on tens- By Giselle

Learning Intention-W.A.L.T- 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 carving = 60 carvings.

I know that 2 tens + 6 tens.

2.37 bananas + 40 bananas=77

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

3.15 + 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 2+ 8 =10 so 10 +10=20 + 7=27
