    Students: Too little
    Student: Okay
    (Students working)
    Student: Maybe we should change our estimate?
    Boy: Okay, write down our estimate.
    Teacher: Okay, what are you up to?
    Teacher Narration: A Down's Syndrome child was
    included in this lesson. He was doing the
    tallying assisted by his aide. At another
    time, he was making sure it was level. So,
    in a number of ways, he was included.
    Teacher: Watch your thumb, Devon. You need to
    move your thumb,
    Devon. Yeah.
    Boy 3: It's too skinny.
    Teacher: Yeah.
    Boy 3: See, I can't even fit them in.
    Teacher: If you hold it like this, yeah, there
    you go. That makes a good funnel.
    Aide: That's another one. Put another line down.
