Use the puzzle as simple a way to passively expose your children to the Arabic numbers while they are mastering their fine motor skills.
Engage verbally with your child, as he/she places the numbers, say the number and show on your fingers how many that represents.
Don’t forget to throw in an occasional word or two of encouragement; “Bravo Ah-layk” for the boys or “Bravo, Ah-lay-kee” for the girls.
