These are basic 2 and 3 phoneme Elkonin boxes. I say a word and the students practice saying the sounds in the word while the circles drop down into the box. You could also say the sounds and have the students guess the word. Sometimes we think of what letter makes the sound and write it in the box. Circles drop on click into the box.
