Lesson objective: Apply solving multi-step equations to a real-world scenario.
This lesson provides an opportunity for students to apply their knowledge and understanding of solving equations to a real-life situation. Students are asked to construct an equation to model a fundraising scenario and then solve for how much money each person made from selling cookies.
Key Concept students will use:
- Equivalent equations have the same solution, and properties of equality allow us to transform equations into other equivalent equations.
Skills students will use:
- Solving equations using the same operation on both sides.
- Simplifying expressions using properties of operations.
Students engage in Mathematical Practice 4 (Model with mathematics) as they write and solve an equation to model the total amount raised for the club.
Key vocabulary:
- equivalent equation
- like terms
- solve
