my new maths goal

My new maths goal

In my maths, I have got a new maths goal. My maths goal is to solve subtraction problems using place value to partition numbers. 

Today in maths we did some of that. We had to solve a problem such as 47 - 38 = ? I we had to solve this problem by working it out like this. 

47 - 30 = 17

17 - 8 = 9

First I halved the 38. then I simply subtracted 47 with the 30 in 38, which equalled 17. Then I subtracted 17 with the 8 in 38, which equalled 9. And there was my answer. It is a really simple and easy way to work it out and I would use it again.
