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
