In our story, 'The Snail and the Whale', there are lots of animals that are all different sizes. Which animal is bigger, the snail or the whale? Which is smaller? Below is a sheet with different sized animals. Can you cut them out and order them from smallest to biggest. If your child is finding this tricky start with 2 or 3 of the pictures and compare them, talking about which is smaller, bigger or longer/ shorter and then extend to using smallest/ biggest, longest/ shortest.
Alternatively, you could find a group of objects from around the house and see if your child can order them from smallest to biggest.
You can also play this game to find the smallest or biggest object or animal on the beach https://www.topmarks.co.uk/early-years/lets-compare
