7th Grade Add, Subtract, Multiply And Divide Using Efficient Written Methods Lesson Plan Example (Math)

Topic: Add, subtract, multiply and divide using efficient written methods

Objectives & Outcomes

• By the end of this lesson, students will be able to add, subtract, multiply and divide using efficient written methods.

Materials

• Pencils
• Paper
• Calculator (optional)

Warm-up

• Review the basics of addition, subtraction, multiplication and division.
• Ask students to solve simple problems using these operations.

Direct Instruction

• Introduce the concept of written methods for addition, subtraction, multiplication and division.
• Explain that these methods are more efficient than using mental math and can be used to solve more complex problems.
• Show examples of the written methods for each operation, using the TI-83 calculator for demonstration purposes.
• Demonstrate how to use the TI-83 to solve problems using the written methods.

Guided Practice

• Divide the class into pairs and give each pair a set of problem cards.
• Have the students work through the problems together, using the written methods to solve the problems on their own calculators.
• Walk around the room and assist students as needed.

Independent Practice

• Assign a project-based problem to the students, such as finding the total cost of a list of items or calculating the average score on a test.
• Have the students use their calculators to solve the problem, using written methods.
• Provide individual or group guidance as needed.

Closure

• Have the students share their solutions to the assigned problem, including written methods.
• Review the key concepts and skills emphasized throughout the lesson.
• Encourage the students to continue practicing their arithmetic skills and using their calculators appropriately.

Assessment

• Observe the students during the guided practice and independent practice activities to assess their understanding of the key concepts and skills.
• Collect and review the students' written solutions to the assigned problem and the calculator-assisted problems to assess their ability to solve arithmetic problems using efficient written methods.
