7th Grade Adding And Subtracting Integers Lesson Plan Example (Math)

Topic: Adding and subtracting integers

Objectives & Outcomes

Students will be able to add and subtract integers with unknowns in both positions.

Materials

Whiteboard and markers

Handout with examples of adding and subtracting integers with unknowns in both positions

Warm-up

Ask students if they have ever added or subtracted integers before. Ask them to share some examples with the class.

Write the following problems on the board:

7 + ? = 12

9 - ? = -2

Have students work in pairs to solve the problems and check their answers with a partner.

Direct Instruction

Introduce the concept of adding and subtracting integers. Explain that when adding integers, we can only combine like terms (terms that have the same sign). Show an example of like terms by writing the corresponding pair of integers with the same sign (e.g. +3 and +6).

Explain that when subtracting integers, we must ensure that the difference is positive and that we can only combine like terms. Show an example of like terms by writing the corresponding pair of integers with the same sign (e.g. -4 and -6).

Review the warm-up problems, demonstrating how to add and subtract integers with like terms.

Guided Practice

Give students individual worksheets with warm-up problems. Have them work through the problems using the steps for adding and subtracting integers with like terms.

As students work, circulate and provide assistance as needed.

Independent Practice

For students' independent practice, have them complete a project-based activity. One option is to have them create a visual representation of how to add and subtract integers with like terms. This could be a poster, a diagram, or a video. Another option is to have them create a game or activity that would help others learn how to add and subtract integers with like terms.

Closure

Review the main points of the lesson: adding and subtracting integers with like terms can be done using addition and subtraction algorithms, and each algorithm has its own set of matching pairs. -Ask students to share one thing they learned about adding and subtracting integers with like terms during the lesson.

Assessment

Observe students during the independent practice activity to assess their understanding of adding and subtracting integers with like terms.

Collect and review their completed worksheets to assess their ability to apply their understanding of adding and subtracting integers with like terms in real-world situations.
