when my kids were small I used to do drawing competitions with them, if a nice day u can do outside as well.
just give them 5 or 10 objects to draw and colour in as best as they can, then one or two adults mark each picture out of 10, the child with the most gets a treat.
another thing we used to do our adventure trails, go for walks and give them a list of things they either need to spot or collect on the way and get them to tick when they have found or collected them.
a big fave of mines as a kid was big pieces of card and a argos book, I used to draw rooms on the card and then cut and glue on things from the catalogue how I wanted my house to look when I was big lol, time consuming and kept me busy for hours.
if I can think of anything else ill come back and post.
