Go on a scavenger hunt with an empty egg box!
Here are some ideas:
* Colour in or paint the bottom of each section of the eggbox then see if you can find objects around the home or garden to match the colours, you could even use fruit or veg (then you can eat it!)
* Shape hunt, see if you can find different mathematical shapes for each section, you could cut the shapes out and stick them inside the lid of the box as a prompt.
* Or, just see what tiny things you can find to fit into each section, maybe inside the house or outside in the garden or on a walk.
