I just printed out a picture of a banana, trace it several times with a black marker on some yellow foam, and cut them out. Then, I simple punch a small hole with a paper puncher and gave them to BirBir to string. After she would string a foam banana, I would make a knot and gave it back to her to string another one, and so on.
She LOVED it and I was so impressed with her concentration and determination!
Fine-motor skills at it’s finest! Threading is always good practice for those little fingers. Of course, the eye-hand coordination is being used here as well.
