We read, The pout-pout Fish Goes to School. It is a cute story but also counts to 4 repeatedly. I used the number cards (1-4) while reading. I used this to start out counting activity. After the story I laid out the number cards randomly. I told Joey we were going to put them in order. Numbers 1-4 were fairly easy for him since we just used them for the story.
After 4 he knew 5 but was confused by 6 and 9. I had him look at the fish on the cards to help him. The fish were placed similarly to the Touch Math Method (Google it, it is a great resource!)
