To warm your brains up, have a go at counting in tens to 100 and then back again. You could sing along to the video below:
Why not start from a different number and count on in tens e.g. 6, 16, 26...
Now that your brain is warmed up, we are going to be exploring money a bit more and looking at how we can give change in a shop.
Imagine you buy a lollipop. It costs 6p but you only have a 10p coin. How much change would you get back?
Find 6 on your number line and count the jumps you need to make to get you to 10. There are 4 jumps, so you need 4p change.
