This week in Te Ngahere we have been learning how to solve word problems in Mathematics. When you are doing maths I would recommend not using place value partitioning for subtraction, because it can be really hard to solve subtraction using place value for example if you had 732-521 you wouldn’t be able to take the 30 from the 20 because 30 is a higher number than 20 and you wouldn’t be able to take the 2 from the 1. I would recommend using the number line instead.
For me it was hard to use place value for subtraction problems but the easy part way to use place value for addition, The second hard thing was when I way trying to figure out with some of the question if they were subtraction or addition.
What strategy would you use to solve subtraction problems?
