Mixed Operations PDF Printable Math Lesson Plan

Lesson Title:”Mixed Operations”

Lesson Objective: Students will be able to solve problems that involve mixed operations (addition, subtraction, multiplication, and division) and understand the order of operations.

Materials:

  • Whiteboard and markers
  • Student worksheets with mixed operation problems
  • Manipulatives (such as base-10 blocks, number lines, and pattern blocks)

    • Introduction (10 minutes):

  • Begin the lesson by asking students if they have ever heard the term “order of operations.”
  • Allow students to share their prior knowledge and misconceptions.
  • Write an example on the board, such as “3 + 4 x 2” and ask students what the answer is.
  • Introduce the concept of the order of operations and explain that it is the order in which we should perform calculations in a math problem (first do any calculations inside parentheses, then exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right).

    • Direct Instruction (20 minutes):

  • Use manipulatives such as base-10 blocks or pattern blocks to demonstrate the order of operations in mixed operation problems.
  • Write an example on the board, such as “5 + 2 x (3 – 1) ÷ 2” and show how to solve it using the order of operations (first do the calculation inside the parentheses, then the multiplication, then the division, and finally the addition).
  • Point out that it is important to follow the order of operations to get the correct answer.
  • Allow students to work through a few mixed operation problems on their own, with guidance and support as needed.

    • Guided Practice (20 minutes):

  • Provide students with worksheets that include a variety of mixed operation problems.
  • Have students work in pairs or small groups to complete the worksheets.
  • Walk around the room and assist students as needed, providing guidance and feedback on their work.

    • Independent Practice (15 minutes):

  • Provide students with a set of individual problems that they can work on independently.
  • Allow students to check their work against the answer key and provide feedback on their understanding of the material.

    • Closure (5 minutes):

  • Review the key concepts of the lesson, such as mixed operations and the order of operations.
  • Address any remaining questions or misconceptions.
  • Assign homework if applicable.

    • Assessment:

  • Observe student work during independent practice
  • Collect and review student worksheets
  • Administer a quiz or assessment at a later date to check for understanding and retention of the material.

    • Note: The above timings is just a suggestion. Depending on the class size, students’ prior knowledge and pacing, the timings may vary. Also, the above plan is just a starting point, you can customize it as per your class needs.
