Sticks and a Sponge
Here is a look at the fine motor, sensory box I put out recently.
I grabbed a bath sponge and her neon stir sticks (from Walmart) and put them in a container. The sticks have a rounded edge so it is a little difficult to poke them in the sponge but she was able to do it. This activity was a great way to strengthen her hands and fingers. It also kept her busy for about 30 minutes.
She was able to remove and reinsert the sticks a lot of times before the sponge got destroyed.
