Introduction to Subtraction up to 5 lesson plan for teachers

Lesson Title:Introduction to Subtraction up to 5

Lesson Objective: Students will be able to understand and solve subtraction problems up to 5 using concrete materials and visual models.

Materials:

  • A set of unifix cubes (or any other manipulatives)
  • Number bonds (or other visual models)
  • Subtraction worksheets (with problems up to 5)

    • Introduction (5 minutes):

  • Begin by reviewing the numbers 1-5 with the students. Have them count aloud with you to reinforce number recognition and counting skills.
  • Introduce the concept of subtraction and explain that it is finding the difference between two numbers by taking away one group from another. Use concrete materials (such as unifix cubes) to demonstrate this concept.

    • Activity 1 (10 minutes):

  • Divide students into small groups and give each group a set of unifix cubes and number bonds.
  • Explain that the number bonds can be used to help them solve subtraction problems.
  • Model solving a simple subtraction problem (such as 5-3) using the number bond and unifix cubes. Show the students how to count the remaining number of cubes.
  • Allow students to work with their partners to solve subtraction problems using the number bonds and unifix cubes.

    • Activity 2 (10 minutes):

  • Provide students with a set of subtraction worksheets.
  • Explain that the worksheets contain simple subtraction problems that can be solved using the strategies learned in the previous activity.
  • Allow students to work independently or with a partner to complete the worksheets.
  • As students work, circulate around the room and provide support and guidance as needed.

    • Activity 3 (10 minutes):

  • Gather the students together and have them share the subtraction problems they solved and the strategies they used.
  • Allow students to explain their thinking and reasoning.
  • Provide feedback and praise for their efforts and progress.
    • Conclusion (5 minutes):
  • Review the concepts of subtraction and the strategies used to solve subtraction problems.
  • Encourage students to continue practicing their subtraction skills using concrete materials and visual models.
  • Remind students that with practice and perseverance, they will become experts in subtraction!

    • Assessment:

  • Observe students as they work on the activities and listen to their explanations of their solutions.
  • Collect the subtraction worksheets and assess the accuracy of the answers.

    • Note: The duration of activities, introduction and conclusion can be adjusted based on the time available in your classroom. Also, you can use different manipulatives and visual models as per the availability.
