Adding on tens -By Giselle

Learning Intention: W.A.L.T - to  make a whole ten.
Success Criteria: I know I am successful when I can add two numbers that makes a whole ten

Problems:  choose numbers that make ten than add the rest to make the numbers


1) 7+ 4+ 3=14
I know its 14 because 7 + 3 = 10 + the 4 = 14

2) 9 + 1 + 7 + 2+= 19
I know its 19 because 9 + 1 = 10 and 7 + 2 = 9 so 10 + 9 = 19

3) 2 + 6 + 3 + 8 + 7
I know its 26 because 8 + 2 = 10 + 7 + 3 = 10 so 10 + 10 = 20 +   the 6 = 26 

4) 9 + 12 + 8 + 11 + 4 =44
I know its 44 11 + 9 + 11= 20 then 12 + 8 = 20 so 20 +20 = 40 + 4 = 44

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
