Mixed Operations for Third Graders Math Lesson Plan

Lesson Title:Mixed Operations for Third Graders

Lesson Objective: Students will understand and apply mixed operations concepts by solving problems and completing interactive activities.

Materials:

  • Mixed operations worksheets
  • Word problem worksheets
  • Whiteboard and markers
  • Manipulative materials (e.g. base-10 blocks, counters, etc.)

    • Introduction (5 minutes):

  • Begin the lesson by reviewing the concepts of addition, subtraction, multiplication and division.
  • Ask students to give examples of when they have used mixed operations in their everyday lives.
  • Show an example of mixed operations problem and ask the students to identify the operations used.

    • Direct Instruction (15 minutes):

  • Use a whiteboard to model mixed operations problems for students.
  • For example, model solving the problem “32 + 8 – 5 x 2 = ?”
  • Explain to students that mixed operations problems require them to use more than one operation to solve the problem.
  • Write the problem on the board: 32 + 8 – 5 x 2
  • Ask students to repeat the problem and the order of operations (PEMDAS)
  • Use manipulative materials to help students visualize the problem and solve it.

    • Guided Practice (20 minutes):

  • Provide students with mixed operations worksheets.
  • Have students work in pairs to solve the problems.
  • Circulate the room to provide individual assistance as needed.
  • After 10 minutes, have students share their answers with the class and provide feedback on any errors.

    • Independent Practice (20 minutes):

  • Give students word problem worksheets that incorporate mixed operations.
  • Have students work independently to solve the problems.
  • Monitor student progress and provide additional support as needed.

    • Closure (5 minutes):

  • Review the main concepts of mixed operations with the class.
  • Ask students to share one thing they learned during the lesson.
  • Remind students to practice their mixed operations skills at home.

    • Assessment:

  • Observe students during independent practice and provide feedback on their understanding of the concept.
  • Collect and grade worksheets to assess students’ grasp of the material.

    • Note:

  • The time allocation for this lesson is approximate and can be adjusted depending on the class pace, student needs, and the teacher’s preference.
  • This lesson plan can be adapted to use different materials and activities that suit the teacher’s style and the student’s learning needs.
  • The teacher may need to adjust the level of difficulty and the complexity of the problems to meet the class’s needs.
  • The use of manipulative materials will help to make the concept of mixed operations more concrete, making it easier for students to understand and visualize.
  • It’s essential to emphasize the order of operations (PEMDAS) when solving mixed operations problems.
  • Encourage students to keep practicing their mixed operations skills to become more fluent in solving problems.
