5th Grade Solve Linear Equation Lesson Plan

Topic: Solve linear equation

Objectives & Outcomes

• By the end of this lesson, students will be able to solve linear equations.

Materials

• Blank paper
• Pencils
• Calculator (optional)

Warm-up

• Ask students to give examples of equalities in their daily life, such as "Jack and Jill are equal to each other" or "zero is equal to zero."
• Ask students to give examples of inequalities in their daily life, such as "Caroline is taller than Emma" or "two is not equal to four."
• Introduce the concept of solving an equation as finding the value of the variable that makes the equation true.

Direct Instruction

• Write the equation "x - 3 = 5" on the board.
• Ask students to identify the variable "x" and the constant "5."
• Explain that we need to find the value of the variable "x" that makes the equation true.
• Suggest that we try x = 4.
• Substitute 4 for x in the equation and get "x - 3 = 5 - 3 = 2," which is true.
• Therefore, the solution to the equation is x = 4.

Guided Practice

• Provide students with a worksheet containing several equations with variables and constants.
• Have students work in pairs to solve the equations and check their answers using the methods described above.

Independent Practice

• Have students work on a lab-based project to practice solving equations.
• Students can work in groups to create a board game or a interactive computer program that models the process of solving equations.
• Students can use the games or program to solve equations and check their answers against a solution sheet.

Closure

• Review the steps for solving linear equations using substitution, elimination, and
• combination.
• Ask students to share their solutions to the equations posed in the warm-up activity.

Assessment

• Observe students during the warm-up activity and the independent practice activity to assess their understanding of solving linear equations.
• Collect and review their solutions to the equations posed in the independent practice activity to assess their ability to solve linear equations.
