Look at this photograph of eggs. They are all different sizes.
Can you point to the biggest egg?
Can you point to the smallest egg?
Can you find an egg that is smaller than the brown egg?
Can you find an egg that is bigger than the speckled egg?
How many eggs are smaller than the brown egg?
Can you find some stones or pebbles in your garden or whilst you are outdoors-you could pretend that these are eggs.
Can you compare them to decide which is biggest/smallest?
Can you arrange them in size order? You might have to keep moving them around a bit until you get it right!
