For quite a few of our favourite fine-motor skills activities we have been using ordinary bath mats. We started with small ones of different colours and used them for coloured bead sorting. The younger person started doing it with fingers, then progressed to measuring spoon/melon ball spoon, the older one first was using sugar tongs, then progressed to tweezers. Tweesers are not so easy with wooden Pony Beads, and we broke few plastic tweezers, then I started giving my older daughter smaller, plastic beads and this seems to work.
We also used coloured water and pipette to fill the suckers.
After a while I thought a challenge was in order, so I pulled out a big transparent bath mat and filled up some pots with food colouring, laid some pipets out (mine are re-purposed from some baby medicine) and quietly left it in the middle of the patio…
Smaller person wanted to have a go immediately, she was just experimenting with how much droplets can one sucker cup hold, then she tried mixing few different colours of droplets in one cup and so on.
Her sister came in from school and wanted to have a go too. She first was working on making colour patters, then decided to make a picture.
All in all – good concentration and maths (patterns) practice! And creativity of course!
