    >> We're going to do a great, a great--
  • 0:09 - 0:11
    we're going to do
    a great task today, guys.
  • 0:11 - 0:19
    Am I selling it? Do you believe me?
    It's going to be a task that asks you guys
  • 0:19 - 0:25
    to be multi-modal, meaning you're going to
    build something, then you're going to
  • 0:25 - 0:31
    gather your data and organize it in a
    table, then you're going to use
  • 0:31 - 0:38
    that technology that we've been practicing,
    the Desmos, to model your data set.
  • 0:38 - 0:42
    And then you're going to interpret your
    data. All the while, we are hoping
  • 0:42 - 0:49
    that you guys are having conversations
    that are sharing your own thinking
  • 0:49 - 0:55
    and pushing the understanding of the other
    people who you're sitting with.
  • 0:55 - 1:00
    To help those conversations, we have on
    your tables, and I know you have these
  • 1:00 - 1:04
    in Miss Grevious’s classroom too, some
    group roles.
  • 1:04 - 1:11
    So, I want you to please pause and to take
    a look at your own group role and to read
  • 1:11 - 1:19
    the words to yourself about, what are the
    questions and contributions
  • 1:19 - 1:27
    that I'm expected to make at my table?
    So I know these are familiar to you.
  • 1:27 - 1:34
    They're not new. But I do want to give
    an opportunity, if there's any questions
  • 1:34 - 1:41
    or anything you're unsure of for your role
    to help support your group today.
  • 1:42 - 1:44
    Okay, great.
  • 1:46 - 1:51
    Then I'm going to pose the problem.
  • 1:55 - 2:02
    The problem is this: you're going to be
    given a rectangular grid
  • 2:02 - 2:07
    that is on centimeter paper.
    There are, as I've written here,
  • 2:07 - 2:15
    19 centimeters across the top,
    25 centimeters along the side.
  • 2:17 - 2:22
    What you're going to be asked to do is to
    figure out, how could I use
  • 2:22 - 2:31
    this amount of grid paper to build a box
    with the largest volume?
  • 2:33 - 2:38
    So, what I'm going to ask, actually, is
    for one student to help me
  • 2:38 - 2:49
    pass out some paper. Don't all jump up at
    once. Thank you so much Disyon. Thank you.
  • 2:51 - 2:57
    And right now, you're not going to do any
    cutting, but you are going to just
  • 2:57 - 3:04
    get one of these pieces of paper and you
    can draw onto it, you would cut squares...
  • 3:04 - 3:10
    Sorry, I need to be more clear. You only
    cut squares out of the side.
  • 3:10 - 3:14
    You cannot cut like a rectangle. You
    cannot cut something that's a 3 by 2.
  • 3:14 - 3:19
    You need to cut an actual square out,
    being a 3 by 3 or a 4 by 4.
  • 3:19 - 3:23
    And you'll cut those out of each side.
    No one's going to cut right now.
  • 3:23 - 3:26
    I just want you to have the paper
    so you can look at it
  • 3:26 - 3:32
    to help you visualize what you'll do.
    Yes, ma'am.
  • 3:32 - 3:35
    >> [background] Are we making a top
    to cover the container?
  • 3:35 - 3:40
    >> That's such a great question. Thank you
    for asking. We are not making a lid.
  • 3:40 - 3:45
    No lid. So it's an open-top box.
  • 3:46 - 3:51
    Okay, so I'm going to ask you individually
    right now. This is not yet time to talk to
  • 3:51 - 3:57
    a partner, but I want you to take a look
    at number one, and it asks you
  • 3:57 - 4:05
    to make a conjecture about how to cut
    squares from the side of your rectangle
  • 4:05 - 4:10
    so that you would build a box
    with the largest volume.
  • 4:10 - 4:13
    Build an open-top box with the
    largest volume.
  • 4:13 - 4:17
    Will you please take a moment
    on your own to think about it and
  • 4:17 - 4:22
    to write into question one,
    what you think.
