Teacher: If we are all using cranberries, how
can we come up with a different answer? Timmy?
Timmy: Because that, um, a cranberry, one of
the cranberries, could be bigger than another.
Teacher: Yeah.
Timmy: Or you could have, um, put it over a
little or under a little.
Teacher: That's right. Some are bigger, some
are smaller. That's just how things work in
nature, so Timmy is exactly right.

Teacher: What would be an average if we had
between twenty-one and twenty-eight? How could
we say, like, well the average number was...?
What would you say it could be?
Boy 2: Twenty-six.
Teacher: And why do you say that?
Boy 2: Cause, um, there's, there's two twenty-
sixes and one and just one of the other numbers.
Teacher: Okay, and is there any other reason?
There are more twenty-sixes than the others.
Emma, what do you think?
Emma: It could be like twenty-five because
twenty-one is farther is like pretty far apart
than twenty-eight and twenty-six and twenty-eight
are only separated by one.
Teacher: Um, huh.
Teacher: So here we say this is the here is our
range. We have between twenty-one and twenty-
eight. That's what you're saying. And if we went
in to the middle, it would be about twenty-five.
