Unit 6 Measuring Length Time Liquid Volume And Weight — Unit Plan

Title	Assessment
Lesson 1 Measure in Halves of an Inch	Length in Half Inches What is the length of the rectangle? Show Solution $\frac{7}{2}$ inches or $3\frac{1}{2}$ inches
Lesson 2 Measure in Fourths of an Inch	Which Ruler? Andre says it would be best to use the ruler marked in quarter inches to measure this pencil. Do you agree? Explain your reasoning. What is the length of the pencil to the nearest fourth of an inch? Show Solution Sample response: Yes. The ruler marked in quarter inches is best because the tip of the pencil falls in between the half-inch marks. $5 \frac{3}{4}$ inches or $\frac {23}{4}$ inches
Lesson 3 Measure in Halves and Fourths of an Inch	How Long? What is the length of the worm in inches? Show Solution $3\frac{3}{4}$ or $\frac{15}{4}$ inches
Lesson 4 Interpret Measurement Data on Line Plots	Interpret and Choose Select all the statements that are true about the measurements in the line plot. Line plot from 0 to 12 by ones.

Lesson 7 Introduction to Liquid Volume	Volume of a Container Reflection What did you learn about the volume of a container and how to measure it? Show Solution Sample response: The volume of a container is how much liquid is needed to fill it. You can use a unit and count how many times you have to use it to fill up a container. It can be hard to compare the volume of liquid if we don’t use the same unit. Liters are units of volume.

Lesson 9 Time to the Nearest Minute	Times Like These 1 What time is shown? _______________ 2 Show 10:13 a.m. on the clock. Show Solution 6:22
Lesson 10 Solve Problems Involving Time (Part 1)	Soccer Time Clare leaves school at 3:25 p.m. Her soccer practice begins at 4:15 p.m. How much time does she have between school and practice? Explain or show your reasoning. Show Solution 50 minutes. Sample response: 3:25 to 3:30 is 5 minutes. Then it’s 45 minutes to 4:15.
Lesson 11 Solve Problems Involving Time (Part 2)	Time and Time Again Solve each problem. Explain or show your reasoning. Jada had a dance class on Saturday. It started at 10:30 a.m. and ended at 11:48 a.m. How long was her dance class? Another day, Jada finished her dance class at 11:55 a.m. The class was 40 minutes long. What time did her class start? Show Solution 78 minutes or 1 hour and 18 minutes. Sample response: I started at 10:30 and jumped 30 minutes to 11:00, 30 more minutes to 11:30, 15 minutes to 11:45, and then 3 minutes to 11:48. I jumped a total of 78 minutes. 11:15 a.m. Sample response: $55 - 40 = 15$
Section C Check Section C Checkpoint	Problem 1 Show 11:49 a.m. on the clock. Show Solution Problem 2 Tyler had to wait in line for a roller coaster. He entered the line at 9:35 a.m. and got on the roller coaster at 10:19 a.m. How long did Tyler wait? Explain or show your reasoning. Show Solution 44 minutes. Sample response: I counted up 25 minutes from 9:35 to get to 10:00, then counted 19 more minutes to get to 10:19. $25 + 19 = 44$ .

Lesson 12 Ways to Represent Measurement Situations	Which Diagram Matches? Which diagram matches this situation? Explain your reasoning. A pumpkin farmer used 52 liters to water 13 seedlings equally. How much water was used on each seedling? A B Show Solution A. Sample response: The diagram has 13 parts and each part represents a seedling, but we don’t know how much water each seedling got.
Lesson 13 Problems with Missing Information	Winner, Winner The winning pig weighed 48 kilograms when his owner decided to show him at the fair. At the fair weigh-off, the pig weighed 124 kilograms. How much weight did the pig gain? Explain or show your reasoning. Show Solution 76 kg. Sample response: $48 + 2 = 50$ $50 + 50 = 100$ $100+24=124$ $2+50+24=76$
Lesson 14 What Makes Sense in the Problem?	A Show at the Carnival A show at the carnival starts at 2:45 p.m. and lasts 47 minutes. What time does the show end? Explain or show your reasoning. Another show that is 24 minutes long ends at 5:10 p.m. Kiran says that the show starts before 4:40 p.m. Do you agree? Explain or show your reasoning. Show Solution 3:32 p.m. Sample responses: From 2:45, it is 15 minutes from 2:45 to 3:00 and another 30 minutes to 3:30. That's 45 minutes, so 47 minutes from 2:45 would be 3:32. I know that 60 minutes from 2:45 is 3:45, and 47 minutes is 13 minutes before 3:45, which is 3:32 p.m. No. Sample response: I know that 4:40 is 30 minutes from 5:10 p.m. If the show is shorter than 30 minutes, it must have started after 4:40. I know that 20 minutes before 5:10 is 4:50, so 24 minutes before 5:10 is 4:46, which is after 4:40.
Lesson 15 Ways to Solve Problems and Show Solutions	Problem Solving Reflection Choose a prompt to respond to. Write a few sentences to reflect on problem solving. The most important part of problem solving is to remember . . . The most important thing to remember when solving problems like we did in this unit is . . . The math in this unit reminded me of _____ from outside of school because . . . Show Solution Answers vary.
Lesson 16 Design a Game	No cool-down
Section D Check Section D Checkpoint	Problem 1 Select the situation that the diagram represents. A.There are 2 bottles of water. Each bottle has 7 liters of water. How many liters of water are there altogether? B.Han put 14 liters of water in 7 bottles. He put the same amount in each bottle. How many liters of water did Han put in each bottle? C.Clare has 7 bottles of water and Jada has 2 bottles. How many bottles of water do they have altogether? D. There are 7 bottles of water. Each bottle has 2 liters of water. How many liters of water are there altogether? Show Solution There are 7 bottles of water. Each bottle has 2 liters of water. How many liters of water are there altogether? Problem 2 A farmer picked 96 kilograms of apples one day. He put the apples in 6 boxes, and the filled boxes all had the same weight. How many kilograms of apples are in each box? Explain or show your reasoning. Show Solution 16 kilograms Sample response: I know $6 \times 10 = 60$ and $6 \times 6 = 36$ so $6 \times 16 = 60 + 36$ . Since 6 groups of 16 kg is 96 kg, there were 16 kilograms in each box.
