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

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

   Let's find the math in a garden together: A planter that is 4 feet long and 2 feet wide has an area of 4 × 2 = 8 square feet — that tells us how many plants fit. If the soil needs to be 1 foot deep, the volume is 4 × 2 × 1 = 8 cubic feet — that tells us how much soil to buy. Gardeners also measure seed depth and the distance between seeds. What other garden decisions need math?

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

   Think it throughA chef is deciding how many portions of a new dish to prepare tonight, based on how many customers are expected. Which math task is this?

   1. AProjecting how much food is needed for the day
   2. BSetting the price of the dish
   3. CDecorating the plate for presentation
   4. DNaming the dish on the menu

   Why is that the answer?

   I chose ___ because ___ .

   Think it throughA gardener knows the size of their planter box and wants to know how much soil to buy to fill it. What should the gardener calculate?

   1. AThe area of the planter
   2. BThe volume of the planter
   3. CThe perimeter of the planter
   4. DThe number of leaves per plant

   How do you know?

   I chose ___ because ___ .
3. 7

   Think it throughLeaving the water running while brushing wastes an average of 4 gallons compared to turning the water on only to rinse. If one person brushes twice a day for a year (365 days), how many gallons would they save by turning the water off?

   1. A730 gallons
   2. B1,460 gallons
   3. C2,920 gallons
   4. D5,840 gallons

   Back to the modelThe chef plans a planter that is 4 feet long and 2 feet wide, filled 1 foot deep with soil. What two different things does the chef calculate about that planter, and why are they different?

   The chef calculates ___ to find how many plants fit and ___ to find how much soil to buy.

Sort it again — on paper this time

Write the letter of the group each one belongs in.

• Calculate the price point for each item
• Decide on the portion size of each item
• Project how much food is needed for each day
• Calculate how much of each ingredient to order
• Calculate the volume of the planter to find the amount of soil needed
• Calculate the area of the planter to decide how many plants to plant
• Measure the distance between seeds
• Measure how deep to plant each seed

Use the words

Fill each blank with a word from the bank.

• A job someone is trained to do, like chef or nurse, is a ___.
• The supply a business keeps on hand, tracked by counting, is its ___.
• The measured amount of food served to one person is a ___.
• The flat space a surface covers, in square units, is its ___.

   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: Believing math only 'counts' when it happens in a classroom — and walking past the calculating, measuring, and projecting inside jobs, hobbies, and chores every day.
2. 10

   Say moreWhen you sorted the chef's tasks from the gardener's tasks, what made a card belong with 'calculating the volume of the planter' instead of 'calculating the area of the planter'?

   This card belongs with volume because it is about ___.

   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.

   If ___ changed to ___ , then ___ .

Last check

These two come from Lesson 9.4. If they are shaky, that is the lesson to revisit — not this one.

   Show what you knowQuick check — you've got this: Which statement best shows what this lesson means by 'math is everywhere'?

   1. APeople use math every day in their professions and hobbies, and it solves problems around the house too
   2. BMath only appears in jobs that involve money
   3. CMath is a school subject with little relevance to life outside the classroom
   4. DOnly trained professionals like chefs are able to use math

   Explain your choice.

   I know it is ___ because ___ .

   From Lesson 9.4Quick check — you've got this: The plant produces 2.5 cars per hour. Using 2.5h = 1,000, how many hours does the order of 1,000 cars take?

   1. A400 hours
   2. B2,500 hours
   3. C997.5 hours
   4. D40 hours
3. 14

   From Lesson 9.4Bakery B charges $2.50 per cupcake with no fee: cost = 2.5n. Solving 2.5n = 110 gives n = 44 cupcakes. Which bakery should Yelina choose to get more cupcakes within her $110 budget?

   1. ABakery A, because 50 cupcakes is more than 44 cupcakes
   2. BBakery B, because 2.5 is greater than 2
   3. CBakery A, because it has a delivery fee
   4. DThey are the same, because both cost exactly $110

Be honest — this tells your teacher what to do next
