Really Good Stuff Tug Of War - Subitizing - 1 deck of 56 cards

I purchased this for my 20 month old son who knows his numbers, but I was unsure if he understood what they all meant. I used these to help show him different forms of the number. He really liked these and I had him counting kids and blocks very quickly from these cards. I did not use it as a game. I simply put all cards representing "one" together and "two" together etc. Then I used them to show him different ways to represent that number and count different things. These are great!
