In reply to Lynsety:
My kids liked it when we used white duct tape doubled over to make post it like labels. Each label I could draw an animal, word, star or number and use them for various games.
Their favourite was drawing spiders on the labels and placing them on holds to avoid like massive jugs.
Stars were good as a target to get to and then come down to limit the height gained or to encourage higher. They could peel them off and stock them to their t-shirt.
