LESSON INSTRUCTION

INTRODUCTION

  1. Begin the lesson by reminding students of the concept of time and its units, minutes and hours.
  2. Tell students that they will be learning how to solve elapsed time word problems.
  3. Show an example of an elapsed time word problem, such as "James started picking pears in the orchard at 8:00. He filled two buckets in 3 hours and then went to lunch. What time was it when James stopped picking pears?"
  4. Ask students what information they would need to solve this problem.

INSTRUCTION

  1. Review the concept of subtraction with the class, explaining how it can be used to solve elapsed time word problems.
  2. Demonstrate to the students how to use number lines to represent elapsed time. Show them how to label the start time, end time, and intermediate times on the number line.
  3. Have students work in small groups of 2-3 to solve elapsed time word problems using clocks or timers to help them keep track of the time.
  4. Provide sentence starters on laminated cards to help students explain their thought process when solving the problems.

GUIDED PRACTICE

  1. Provide students with an elapsed time word problem worksheet pack.
  2. Work through the first problem together as a class, demonstrating how to use the number line and subtraction to solve the problem.
  3. Have students work in small groups to solve the rest of the problems on the worksheet pack.
  4. Circulate around the room to provide individual support and guidance as needed.

    INDEPENDENT PRACTICE

    1. Provide students with another elapsed time word problem worksheet to complete independently.
    2. Encourage students to use the number line and subtraction to help them solve the problems.
    3. Circulate around the room to provide individual support and guidance as needed.

      HOMEWORK

      1. Assign an elapsed time word problem worksheet as homework for students to complete.
      2. Encourage students to use the number line and subtraction to help them solve the problems.

        EXIT TICKET

        1. To assess students' understanding of solving elapsed time word problems using subtraction, provide each student with an exit ticket that contains two elapsed time word problems.
        2. Instruct students to solve each problem and explain their thought process using the sentence starters provided on the laminated cards.
        3. Collect the exit tickets to quickly assess students' understanding of the concept and identify any areas that may require further instruction or support.

          ASSESSMENT

          1. To assess students' understanding of solving elapsed time word problems using subtraction and number lines, provide each student with an assessment sheet that contains several elapsed time word problems.
          2. Instruct students to solve each problem and explain their thought process using the sentence starters provided on the laminated cards.
          3. Collect the assessment sheets to evaluate students' understanding of the concept and identify any areas that may require further instruction or support.

            CLOSURE

            1. Recap with the class what they learned in the lesson about solving elapsed time word problems using subtraction and number lines.
            2. Encourage students to reflect on how they can apply these strategies in future math lessons and in everyday situations.
            3. Provide positive reinforcement to the class for their hard work and progress throughout the lesson.

              EXTENSION

              1. For students who have mastered solving elapsed time word problems, provide them with more challenging problems that involve multiple intermediate times or more complex start and end times.
              2. Students can create their own elapsed time word problems and exchange with a partner to solve.
              3. Students can research and create a timeline of a significant historical event, using elapsed time and number lines.

              INTERVENTION

              1. For students who struggle with subtraction, provide them with additional practice problems and one-on-one guidance during independent practice.
              2. For students who have difficulty keeping track of time, provide them with a timer or visual cues, such as a clock or hourglass.
              3. For students who need additional reinforcement, provide them with visual aids, such as posters or anchor charts, that illustrate the process of solving elapsed time word problems using subtraction and number lines.

              TEACHING TIPS

              1. Model how to read and interpret word problems.
              2. Use visual aids, such as a clock, to reinforce the concept of elapsed time.
              3. Provide opportunities for students to practice solving word problems independently.

              STUDENT MISCONCEPTIONS

              1. Not understanding the concept of elapsed time.
              2. Difficulty determining the starting and ending times.
              3. Struggling with subtracting the starting time from the ending time.
