All about maths

Today we did maths and we were learning to use a range of strategies to solve a given problem.

Our first one was: Tumaru has twenty seven lollies, he buys eighteen more and then eats fourteen. How many lollies does Tumaru have left?

Here are the strategies we used:  

20+10=30

7+8=15

30+15=45

45-14=31

18-14=4

4+32=36

36-5=31

27+18=45

45-14=31

That was the first problem. This was the next one: Levron had thirty four trading cards. He played Dayton and lost twelve. Then he played Tanginoa and won twenty six. How many trading cards does Levron have now?

Here are the strategies we used:

34-12=22

22+26=48

30-10=20

4-2=2

22+20=42

42+6=48

34-12+26=48

34+26=60

60-10=50

50-2=48

Because we were able to use a range of strategies to solve each problem we were able to achieve our learning intention.
