Subtraction Strategies for First Graders Lesson Plan

Lesson Title:Subtraction Strategies for First Graders

Lesson Objective: Students will understand different subtraction strategies and be able to apply them to solve subtraction problems.

Materials:

  • Number cards (1-10)
  • Counters (such as small bears or blocks)
  • Subtraction worksheets
  • Chart paper
  • Markers

    • Introduction (5 minutes):

    1. Begin the lesson by reviewing the concept of subtraction as taking away.
    2. Write the subtraction equation 2-1 = 1 on the chart paper and ask the students to count the counters and identify how many are left after one is taken away.
    3. Introduce the idea that there are different strategies for solving subtraction problems.

    Direct Instruction (15 minutes):

    1. Introduce the strategy of counting backwards.
    2. Write the subtraction problem 5-3 on the chart paper and have the students count backwards from 5 to find the answer.
    3. Introduce the strategy of using a number line.
    4. Write the subtraction problem 7-4 on the chart paper and have the students use a number line to find the answer.
    5. Introduce the strategy of using manipulatives (counters).
    6. Pass out counters to the students and have them solve the subtraction problem 6-2 using the counters.

    Guided Practice (20 minutes):

    1. Pass out the subtraction worksheets to each student.
    2. Have the students work with their partners to complete the subtraction problems on the worksheets using the different strategies introduced.
    3. Circulate around the room to assist and check for understanding.

    Independent Practice (10 minutes):

    1. Have the students complete a few problems on the worksheet independently, encouraging them to use the different strategies they have learned.
    2. Provide extra support and assistance as needed.

    Closure (5 minutes):

    1. Review the different subtraction strategies with the students.
    2. Have a few students share which strategy they found most helpful for solving a problem.
    3. Remind the students that there are different ways to solve subtraction problems and encourage them to try out different strategies.

    Assessment: Observe students during independent practice, check the subtraction worksheets and informally assess students’ understanding of the different subtraction strategies using verbal questions. Also, check students’ use of visual aids and if they are able to use them correctly to solve the problems.
