Lesson Plan on Subtraction Skill Builders for First Graders

Lesson Title:Subtraction Skill Builders for First Graders

Lesson Objective: Students will be able to solve subtraction problems using manipulatives and understand the concept of subtraction as taking away.

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 addition and counting using manipulatives (counters).
    2. Ask the students to count the counters and practice adding more counters.
    3. Introduce the concept of subtraction as taking away.
    4. 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.

    Direct Instruction (15 minutes):

    1. Pass out the number cards (1-10) to each student.
    2. Have the students work with partners and use the counters to create subtraction equations using the number cards.
    3. Call on a few students to share their subtraction equations and have the class solve them together using the counters.
    4. Write the subtraction equations on the chart paper and have the students help solve them.

    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 counters to visualize the problem.
    3. Circulate around the room to assist and check for understanding.

    Independent Practice (10 minutes):

    1. Have the students complete the last few problems on the worksheet independently. 2. Provide extra support and assistance as needed.

    Closure (5 minutes):

    1. Review the concept of subtraction as taking away with the students.
    2. Have a few students share one of the subtraction problems they solved during the lesson.
    3. Remind the students that subtraction is an important math skill and will be used in many areas of their lives.

    Assessment: Observe students during independent practice, check the subtraction worksheets and informally assess students’ understanding of the subtraction concept using verbal questions.
