You did these with your group. Now do them on your own — the model above is yours to copy.

1. 1

   Same stepsFinish what the group started. Use the model above, step for step.

   Try it together — then prove it: New question: "How many pets does each student in our class have?" Will every student give the same answer, or different answers? Some students have 0 pets and others have 2 or 3, so the answers vary. Is this statistical or not statistical? Now a different question: "How many days are in one week?" Does this have one fixed answer or many? Now prove it: say why that move had to work at all — not just that it did.

   Warm restartA box has a base area of 10 square inches and a height of 4 inches. What is its volume?

   1. A40 in³
   2. B14 in³
   3. C40 in²
   4. D2.5 in³

   Warm restartWhat is the volume of a rectangular prism with l = 6 cm, w = 2 cm and h = 3 cm?

   1. A36 cm³
   2. B11 cm³
   3. C36 cm²
   4. D18 cm³

   Warm restartA prism has a base area of 10 square feet and a volume of 40 cubic feet. What is its height?

   1. A4 feet
   2. B400 feet
   3. C30 feet
   4. D50 feet

   How do you know?

You answered these out loud. Now write them.

Answer, then say how you know — the reason is the part that counts.

1. 5

   Think it throughWhich question is statistical?

   1. A'How many goals did each player score this season?'
   2. B'How many goals has the team scored total?'
   3. CBoth are statistical
   4. DNeither is statistical

   Why is that the answer?
2. 6

   Think it throughWhy is the team total NOT a statistical question?

   1. ABecause it has exactly one answer, with no variability
   2. BBecause totals are never useful
   3. CBecause it is about soccer
   4. DBecause you cannot count goals

   How do you know? Give a second reason as well.
3. 7

   Think it throughWhich of these is a statistical question?

   1. AHow tall are the students in my class?
   2. BHow tall am I?
   3. CWhat is today's date?
   4. DHow many minutes are in an hour?

   Explain your thinking. What would have to change for a different choice to be right?
4. 8

   Back to the modelWhat pattern do you notice about statistical questions compared to non-statistical questions?

Sort it again — on paper this time

Write the letter of the group each one belongs in.

• How many points does each player on the team score per game?
• How many players are on the roster?
• What is the free-throw percentage of each player?
• What color are the team jerseys?
• How many minutes does each player practice per week?
• How many quarters are in a basketball game?
• How far can each player throw the ball?
• What is the height of each player on the team?

Use the words

Fill each blank with a word from the bank.

• A question that expects varied answers you can collect is a ___ ___.
• A question that expects a variety of answers and is answered by collecting data is a ___.
• A question that has one fixed answer and does not need data collection is a ___.
• Facts or numbers collected to answer a question are ___.

1. 9

   Find the mistakeAnother student made this exact mistake in this lesson. Explain why it is wrong, then write what they should have done.

   The mistake: A common mistake in Statistical Questions and Data is judging a question by its topic or its numbers instead of its variability.
2. 10

   Say moreWhile sorting the questions, what clue tells you instantly that a question will need DATA from many players to answer?
3. 11

   Write your ownWrite your own problem about this situation, then solve it and show the answer. The situation: Five national park photographs are lined up on the board before you clock in as today's basketball data analyst. All kinds of questions could be asked about these parks.

These two come from Lesson 1.6. If they are shaky, that is the lesson to revisit — not this one.

   Show what you knowExplain your thinking — Which question is a statistical question? A) How many students are in the school? B) How many hours does each student in 6th grade exercise per week? C) What time does school start? D) How many days are in a week?

   1. AHow many hours does each student exercise per week?
   2. BHow many students are in the school?
   3. CWhat time does school start?
   4. DHow many days are in a week?

   Explain your choice.

   From Lesson 1.6Explain your thinking — Which statement best captures what this lesson means by 'Math is Ours'?

   1. AWe are a community of math thinkers and doers — we work together and on our own, showing respect for our classmates, our community, ourselves, and our math ideas
   2. BMath belongs to whoever finishes first
   3. CWorking together means one person solves while the others watch
   4. DGetting stuck means math is not for you

3. 14

   From Lesson 1.6Why should the class agree on both a together-agreement and an alone-agreement?

   1. ABecause working alone matters more than working together
   2. BBecause math class includes both kinds of work, and each kind needs its own way to support the whole community
   3. CBecause agreements for working together are only for advanced students
   4. DBecause agreements about working alone don't affect other students
