statements of multiplicative comparisons as multiplication equations.Materials Paper and pencil, chart paper or white boardTask Present the following problem to students:

A donut shop makes three times as many donuts as pastries. If the shop makes 186 donuts per day, how many pastries do they make?How can we compare the amount of donuts to the amount of pastries?

Using Think-Pair-Share, ask students to think independently about how they might use multiplication to compare the numbers. Give them a brief time to talk with a partner, then ask them to share their thoughts.Record their statements on chart paper or a white board as sentences and/or equations.

Examples:There are three times as many donuts as pastries. 3 x pastries = donuts 3p = d 186 = 3 x pastries 186 ÷ 3 = 62 62 x 3 = 186

There are one third as many pastries as donuts. 1/3 x donuts = pastries 1/3d = p

Also, draw a comparison model to show the amounts:186 donuts

1/3 1/3 1/3

Ask students to generate additional examples of multiplicative comparisons, and see if they can state the inverse and/or the equations.

Examples: I have five times as many toes as feet. I have one fifth as many feet as toes.5 x feet = toes 1/5 x toes = feet

There are half as many boys in our class as girls. There are twice as many girls in our class as boys. boys x 2 = girls ½ x girls = boys

Use the Activity Sheet Donut Shop for additional practice.

Limited Performance Tasks 1 & 2:

This student may or may not be able to draw appropriate models for 3 x 8 = 24 and 8 x 3 = 24 (i.e., array model), and label them correctly.

Task 3:The task is not attempted or the student’s response shows that they cannot generate a real life example of a multiplicative comparison.

Not Yet Proficient Tasks 1 & 2: The student can create

appropriate models for 3 x 8 = 24 and 8 x 3 = 24 (i.e., array model), and label them correctly. The student’s models show that 3 groups of 8 make 24 and that 8 groups of 3 make 24. The student understands that 24 is being grouped in different ways. We say 24 is 8 times as much as 3 because it takes 8 threes to make 24. We say 24 is 3 times as much as 8 because it takes 3 eights to make 24.

The fourth graders collected 210 cans of food this week during their canned food drive for the community center. On Monday, they collected 70 cans. On Wednesday, twice as many cans were collected as on Monday. How many cans did the students collect on Wednesday?

Ask students to model/explain their solutions.Possible responses:

210 cans in all 70 cans

onMonday

70 = 210 ÷ 3 The amount of cans collected on Monday was one third as much as they70 = 210 x 1/3 collected all week. Seventy is one third of 210. Seventy times 3 is 210.70 x 3 = 210

210 = 70 + c The total amount of cans is equal to 70 cans plus the amount collected on Wednesday (unknown).

70 x 2 = 140 The amount of cans collected on Monday was half as much as the number140 ÷ 2 = 70 of cans collected on Wednesday. The amount collected on Wednesday140 x ½ = 70 was twice as much as the amount of cans collected on Monday.

Problem C: 8 Josh had 53 cookies. Seven cookies fit into each of his snack bags. What would be the fewest number of bags he would need in order to hold all of his cookies?

53 ÷ 7 = p; p = 7 r 4; Josh needs 8 bags to hold all of the cookies. Problem D: 7 or 8 Josh had 53 cookies. He divided them equally among his friends.

Then, he gave the leftovers away, one each to some of his friends. How many cookies could his friends have received? 53 ÷ 7 = p; p = 7 r 4; Some of his friends received 7 cookies. Four friends received 8 cookies.

A banquet company provides options for table arrangements: triangular tables, square tables, and hexagonal tables. For each type of table, you can fit 1 person on each side of the table. For their parties they want to put all of the tables together so that every table shares at least one side with another table.

Part 1:Based on this proposed arrangement, how many people could you sit at 1 triangular table? 2 connected triangular tables? 3 connected triangular tables? 4 connected triangular tables?

Part 2: Based on this proposed arrangement, how many people could you sit at 1 square table? 2 connected square tables? 3 connected square tables? 4 connected square tables?

Part 3: Based on this proposed arrangement, how many people could you sit at 1 hexagonal table? 2 connected hexagonal tables? 3 connected hexagonal tables? 4 connected hexagonal tables?

Part 4: For each type of table, write a sentence explaining how many more seats get added every time you add a new table. Explain how you found your answer.

4.OA.5 - Task 3Domain Operations and Algebraic ThinkingCluster Generate and analyze patterns.Standard(s) 4.OA.5 Generate a number or shape pattern that follows a given rule. Identify apparent

features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.

Materials Activity sheetTask Lawn Mowing Business

Ted and Nancy both mow lawns during the summer to earn money.Ted charges $10 per lawn and $2 per hour.Nancy charges $4 per lawn and $4 per hour.

Part 1:Complete the table to show how much Ted and Nancy would each earn based on the amount of time that it took to mow a lawn.

Ted Nancy½ hour1 hour

2 and ½ hours3 hours

3 and ½ hours4 hours

Part 2:Explain how you found the amount for both Ted and Nancy in the table.

Part 3:Last week, Ted and Nancy each mowed 3 lawns that took 1 and ½ hours each, and 7 lawns that took 3 hours each. How much money did they each earn? Write an equation to show your work.
