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.
