Section Summary

Details

In this section, we solved all kinds of problems about time, weight, and liquid volume. We did so using addition, subtraction, multiplication, and division, as well as different reasoning strategies.

Clare spent 48 minutes at the carnival. She left the carnival at 12:10 p.m. What time did she get to the carnival?

Subtraction problem for figuring out how long Clare spent at the carnival.

A cow made of butter weighs 273 kilograms. That is 277 kilograms less that the actual cow. How much does the actual cow weigh?

Addition. Two-hundred seventy-three plus two-hundred seventy-seven equals five-hundred fifty.

Problem 1 (Lesson 12)

Lin’s class got 8 pumpkins for a pumpkin carving contest. Each pumpkin weighed 12 pounds.

  1. Which tape diagram represents the situation?

    1. Diagram. Rectangle divided into 12 equal parts, each labeled 8. Total, question mark.
    2. Diagram. Rectangle divided into 8 equal parts, each labeled 12. Total, question mark.

  2. How many pounds did the pumpkins weigh altogether? Explain or show your reasoning.

Problem 2 (Lesson 13)

A family brought two pigs to the fair. The first pig weighed 153 kg. The second pig weighed 66 kg less. How much did the second pig weigh?

Problem 4 (Lesson 15)

Jada arrived at the fair at 10:15 a.m. She left the fair at 11:47 a.m. How many minutes did Jada spend at the fair? Explain or show your reasoning.

Problem 5 (Exploration)

Analog clock with no numbers.

Jada sees this image of a clock in a mirror. What time is it? Explain your reasoning.

Problem 6 (Exploration)

Three pumpkins at the fair weigh a total of 1,000 kg.

  1. What is one possibility for the 3 pumpkin weights?

  2. The lightest of the 3 pumpkins is 255 kg. What is a possibility now for the 3 pumpkin weights?

  3. The heaviest of the 3 pumpkins is 428 kg. How much does the 3rd pumpkin weigh?
