Here is a picture of my cards with the counting grids attached.
I was thinking we could put one nut on each square of the grid. Not too fancy but good for his one to one correspondence. I thought it would be fun for fall. I put the cards and grids on my Scribd account if you are interested. I made them for the numbers 1-10. All you need to do is cut out the grids and cards and then glue the grid to the back of the card.
