Lesson 11 Solve Problems Involving Time (Part 2)

    • Let’s solve more problems involving time.

Warm-up Notice and Wonder: Band Practice

A bus.

What do you notice? What do you wonder?

Han ate his dinner before he caught a bus.
When he got off the bus, he had to hurry to get to band practice on time.

Activity 1 On the Bus Again

  1. For how many minutes was Han on the bus? Explain or show your reasoning.

    the time Han got on the bus:

    Analog clock.

    the time Han got off the bus:

    Analog clock.

  2. Draw the minute hand to show that Elena waited for the bus for 32 minutes.

    the time Elena started waiting:

    Analog clock.

    the time Elena got on the bus:

    Analog clock showing time.

Activity 2 Math Libs Time

For each problem, fill in a name and an activity, and then solve the problem. Show your thinking. Organize it so it can be followed by others.

  1. started at 8:25 a.m. and finished at 8:50 a.m. How much time was spent doing that activity?

  2. finished at 5:38 p.m, after spending 20 minutes. What was the start time?

  3. started at 10:45 a.m. and finished at 11:18 a.m. How much time was spent on it?

  4. started at 3:30 p.m and took 45 minutes to complete it. What was the finish time?

Practice Problem

Problem 1

Andre started soccer practice at 3:45 p.m. He left school 75 minutes earlier.

  1. Show the time Andre left school on the clock.

    Analog clock with no hands.

  2. Andre was at soccer practice for 110 minutes. What time did soccer practice end? Explain or show your reasoning.
