In this first clip he is working on multi-syllabic words. In order to get him to slow down an annunciate, his therapist uses colored chips to represent each syllable. Here he's saying the word "watermelon".
Here's "basketball" and "butterfly". Notice how he zooms through butterfly and says "bu-ter-fy".
In this last clip, he is using the colored chips to represent individual words in the sentence "The lizard is looking for food." He is still working on verb tenses, so you'll hear him leave of -ing in looking.
