Very simply, these are 3 1/2 " x 5" cards with a single realistic photo and the initial sound printed below. The consonents are pink and the vowels are blue.
I used to keep a set in a basket on the shelf with my early language work. They are nice for playing oral language games and the children would often take the basket and play the games with their friends.
You can also use them as a matching card game, cut the letter apart from the photo and make puzzles, match the letters from the movable alphabet... and I'm sure you can think of more!
