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.

   Let's do one together: Try 200 quarters, 25 dimes, 15 nickels, and 25 pennies. Do they make exactly $53.50? What are 200 quarters worth? (200 × $0.25 = $50.00) Add 25 dimes. What is the new total? (25 × $0.10 = $2.50, so the total is $52.50.) What are 15 nickels worth? What are 25 pennies worth? (15 × $0.05 = $0.75 and 25 × $0.01 = $0.25) Add all four values. Is the total $53.50? ($50.00 + $2.50 + $0.75 + $0.25 = $53.50. Yes.) Is 25 pennies a multiple of 5? (Yes. 5 × 5 = 25, just as the pattern said.)

   My first step is ___ , because the problem asks for ___ .

   Warm restartWhich box holds more — one that holds 20 cubic inches, or one that holds 30 cubic inches?

   1. AThe 20 cubic inch box
   2. BThe 30 cubic inch box
   3. CThey hold the same
   4. DYou cannot tell

   Warm restartA cube is 2 cm long on every edge. What is its volume?

   1. A4 cubic cm
   2. B6 cubic cm
   3. C8 cubic cm
   4. D12 cubic cm
4. 4

   Warm restartA box is 2 cm long, 3 cm wide, and 2 cm tall. What is its volume?

   1. A7 cubic cm
   2. B10 cubic cm
   3. C12 cubic cm
   4. D24 cubic cm

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 throughPlayer A had scored 18 points before making 10 two-pointers in a row. Using the pattern rule of adding 2 points per shot, what is Player A's final score?

   1. A20
   2. B28
   3. C36
   4. D38

   Why is that the answer?

   I chose ___ because ___ .
2. 6

   Think it throughPlayer B had 6 points before scoring 10 three-pointers in a row. Using the pattern rule of adding 3 points per shot, what is Player B's final score?

   1. A16
   2. B30
   3. C36
   4. D38

   How do you know?

   I chose ___ because ___ .
3. 7

   Think it throughAfter using the pattern rules to find both players' final scores, how can the players check that their totals are reasonable?

   1. AMultiply the two final scores together
   2. BRound both totals to the nearest ten
   3. CList the score after each shot in a table of values and confirm the sequence lands on the final totals
   4. DCompare the players' shooting percentages

   Explain your thinking.

   I chose ___ because ___ .
4. 8

   Back to the modelAkela's change jar has coins worth $53.50. Why is 'every 100 of a coin is worth 100 times one coin's value' a pattern, while 'Akela's jar holds $53.50' is not?

   This is a pattern because it works for ___ amount of coins.

Sort it again — on paper this time

Write the letter of the group each one belongs in.

• Each number in Player A's points is 2 greater than the number before it.
• The pattern rule for Player B is to add 3.
• Every 100 of a coin is worth 100 times one coin's value.
• The number of pennies in the jar must be a multiple of 5.
• Player A had 18 points before the streak started.
• Akela's jar holds $53.50.
• Player B finished with 36 points.
• A sei whale measures 4.5 meters long at birth.

Use the words

Fill each blank with a word from the bank.

• Something that repeats or changes in a predictable way is a ___.
• The instruction for getting from one term to the next is the ___ ___.
• A statement true for a whole pattern, not just the cases you tried, is a ___.
• A table listing each step of a pattern in order is a ___ ___ ___.

   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: Reporting only the points from the streak (20 or 30) and forgetting to add the points each player had before the streak began.
2. 10

   Say moreThe whale card was tricky: 'a sei whale measures 4.5 meters at birth' is a starting value, and the growth pattern adds about 2.5 centimeters each day. Why does a pattern need BOTH a starting value and a rule?

   The starting value is ___, and the rule is ___.

   Change one numberGo back to Part 1 and pick one problem you already solved. Change one number in it, then solve your new version. Show every step.

Last check

These two come from Lesson 1.4. If they are shaky, that is the lesson to revisit — not this one.

1. 12

   Show what you knowQuick check — you've got this: Which statement best captures what this lesson means by 'Math is Finding Patterns'?

   1. AWe look for patterns and relationships, use them to solve problems and make generalizations, and check our solutions for reasonableness
   2. BPatterns are decorations that make problems look nicer
   3. CA pattern rule only works if you also count every item one at a time
   4. DOnce you spot a pattern you never need to check your answer

   Explain your choice.

   I know it is ___ because ___ .
2. 13

   From Lesson 1.4Quick check — you've got this: Which statement best captures what this lesson means by 'Math is Explaining and Sharing'?

   1. AWe communicate our reasoning, listen to classmates' arguments, decide whether they are convincing, and check our calculations for accuracy
   2. BWe keep our methods private so nobody can copy our answers
   3. CAn argument only counts in math if it uses equations
   4. DOnce you have an answer, checking it a second way is a waste of time
3. 14

   From Lesson 1.4The group decides to decompose the garden bed design into simpler shapes to find its volume. What does that method involve?

   1. ABreaking the figure into rectangular prisms, finding each prism's volume, then adding them
   2. BAdding the areas of each face of the figure
   3. CMultiplying the total length by the total width only
   4. DAveraging the volumes of similar containers they've seen before
