WALT: Add and Subtract.
This week in Maths teacher lesson always to look at the number on the right before answering. The reason why to do this is so that you know if the number is going to end up in the next column. For example: 273+183=?. The way that I solve this is by doing this, 3+3=6, 170+180=350 then add the other hundred. The answer that I ended up with in the end is, 456. So my advice for you is to use this way to solve addition and subtraction questions.
