This week, you will looking at strategies to solve addition number problems.
The first thing we would like you to do, is to have a discussion with your grown up about which method you remember learning in class. Below is two videos for you to have a look at. Some of you will be working on expanded method and some of you will be doing formal column method. Watch both videos and decide which you feel more confident with.
Expanded Column Method
Use your chosen method, pick one number from each side and add them together. Use a calculator to check your answer! With any you have got wrong, talk to an adult and try again by revisiting the video and doing the strategy again.
