We also used m&ms to find a letter or a sound. You could use any edible treat like marshmallows, gum drops, and goldfish crackers. You can find this ABC chart here.
Then we used a treat to find where they hear a particular sound either at the beginning, middle or end of a word. For example, this smartie found the Xx sound at the end of the word.
I used Deanna Jump's Stretchy the Snake from this packet.
Stay warm! We have been inside with no recess for the past week!
