Addition

Today we will be looking at addition.

To warm up, we're going to do a quick starter to refresh our memories of number bonds. We'll be using our number bonds today when we're adding carefully.

On the next few slides are some questions for you to have a go at independently. We have to wait for everybody to complete the question before it moves on, so while you're waiting, check your answer!
