Use the construction paper, the pen and the scissors to cut out letters of the alpha-bet. You will need more than 1 of each letter. You can also use pre-cut letters.
Spread the letters on the floor or a mat in a random order. Help the child lay prone on the therapy ball. The child should be able to touch the floor. Instruct the child to use his hands and reach out to grab one letter at a time, then to walk back and place the letter in front of them. After the child gets all the letters he needed, he can spell the word.
You can also use magnetic letters and a magnetic board, or use math equations where the child has to walk out and grab the correct answer.
