This week we will be working on addition and subtraction, starting with mental or informal written methods before moving onto the column method later in the week.
Here are some suggestions for how you might choose to work out the answers to your questions in the first half of the week. You should use the method that works best for you. Note that some will be more suitable than others depending on the size of the numbers you are asked to use.
If you need a reminder of how to use the column method to add and subtract, here is a visual guide. There is also a step by step guide on your activity sheet.
