Lesson Title:Introduction to Mixed Operations

Lesson Objective: Students will be able to understand and solve mixed operations problems (addition and subtraction) using concrete materials and visual models.

Materials:

  • A set of base ten blocks (or any other manipulatives)
  • Number lines (or other visual models)
  • Mixed operations worksheets (with problems that include addition and subtraction)

    • Introduction (5 minutes):

  • Begin by reviewing the concepts of addition and subtraction with the students. Have them count aloud with you to reinforce number recognition and counting skills.
  • Introduce the concept of mixed operations and explain that it is solving a problem that includes both addition and subtraction. Use concrete materials (such as base ten blocks) to demonstrate this concept.

    • Activity 1 (10 minutes):

  • Divide students into small groups and give each group a set of base ten blocks and number lines.
  • Explain that the number lines can be used to help them solve mixed operations problems.
  • Model solving a simple mixed operations problem (such as 8+3-2) using the number line and base ten blocks. Show the students how to count the total number of blocks and then take away some blocks to find the final answer.
  • Allow students to work with their partners to solve mixed operations problems using the number lines and base ten blocks.

    • Activity 2 (10 minutes):

  • Provide students with a set of mixed operations worksheets.
  • Explain that the worksheets contain problems that include both addition and subtraction.
  • 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 mixed operations 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 mixed operations and the strategies used to solve mixed operations problems.
  • Encourage students to continue practicing their mixed operations skills using concrete materials and visual models.
  • Remind students that with practice and perseverance, they will become experts in mixed operations!

    • Assessment:

  • Observe students as they work on the activities and listen to their explanations of their solutions.
  • Collect the mixed operations 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.
