Make letter sounds a game for pre-readers using these letter cards. After you demonstrate, learners take turns drawing letters out of a bag. Weight them for the letters they have been practicing most recently. Once they've chosen a letter, they say the sound and show it to the group (small groups would work best to keep kids engaged). The overall idea here is something you could easily pick up and practice any time, and adding more letters is a quick way to increase the skill difficulty.
