Objective

By the end of this lesson, you will be able to apply algebraic concepts to solve problems related to working out with weights.

Materials and Prep

• Paper and pencil
• Calculator (optional)
• Basic knowledge of algebraic expressions and equations

Activities

1. Create an algebraic equation:

   • Think of a specific weightlifting exercise you want to focus on.
   • Identify the variables involved, such as the weight lifted, the number of repetitions, and the total weight lifted.
   • Write an algebraic equation that represents the relationship between these variables.

2. Solve the equation:

   • Choose specific values for the variables in your equation.
   • Substitute the values into the equation and solve for the unknown variable.
   • Interpret the solution in the context of your weightlifting exercise.

3. Create word problems:

   • Think of different scenarios related to weightlifting and create word problems that involve algebraic equations.
   • Share the word problems with a partner and solve them together.
   • Discuss how algebra can be applied to real-life situations like working out with weights.
