Can you play 'I Spy', seeing what you can see around your house. See if you can write a list of all the different things that you have seen.
Go on a shape hunt and see if you can spot any circles/triangles/rectangles/squares. Can you tell your grownup how you know what the shapes are? Eg, 'it is a square because it has 4 sides that are all the same length'.
Have a look in your garden and see if you can find any bugs, can you identify what they are?
