One day after we returned home, I spread the cards out all over the floor of the deck, and we played "Alphabet Stomp!" I called out letter names or sounds, and the girls found the letters and stomped on them.
After playing for a while, we put the letters in ABC order.
Then we walked along our alphabet path and said the letter names or sounds as we walked.
Lastly, O(5) and I had fun making words with the letter cards.
My favorite thing about this activity was that we did it outside! I love for our girls to spend as much time outside as possible. They usually spend their outside time digging in the dirt and making various stews and soups out of dirt, sand, gumballs, leaves, etc, but occasionally we'll "play" school, too :)
