The twins came home from school today and I printed ups some math practice sheets for them to try.  They are just starting addition and use their fingers.  So 5 + 0 = five fingers (let hand) plus zero fingers (right hand).  3 + 2 = 3 fingers and 2 fingers.  The right and left hand is involved here.  Joey is doing 4 + 6 and says "But Mom, I don’t have six fingers".  LOL!  I had to think about it but he is right.  He does not have 6 fingers on one hand.  He is my son alright!
