Learning basic sewing with a polystyrene plate, yarn, + plastic needle. I remember doing this with craft mesh when I was a kid and then graduating to sewing buttons by hand onto little pillows and pockets.
Simple preschool color matching activity that will also work on fine motor skills -- pushing colored popsicle sticks into an old coffee can! This activity not only develop cognitive skills, but and fine motor
Draw a letter on a pin board and have children push the pins in correct order to form the letters. (Could write numbers and even draw arrows to show letter formation sequence.) Great for fine motor skill development and letter formation and recognition
Great fine motor activity that also works on number recognition and matching. Instead of numbers you could also write letter on the sticks and box. And you could math problems on the sticks with answers on the box.
