Algebraic Budgeting: Plan a School Event Budget

Grade 9Math1 days
This project engages 9th-grade math students in planning a school event budget using algebraic substitution. Through solving multi-variable equations and incorporating real-life budgeting constraints, students employ algebraic concepts to model financial situations, analyze budget scenarios, and present their findings. By the end of the project, students will develop skills in substitution, problem-solving, and analytical thinking, as well as improving their ability to communicate mathematical ideas effectively.

Common Core Standards

CCSS.MATH.CONTENT.HSA.CED.A.2
Primary
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.Reason: This standard applies as students will create equations involving variables representing budget constraints and costs for a school event.
CCSS.MATH.CONTENT.HSA.REI.A.1
Secondary
Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.Reason: Students will justify their process of substitution and solving algebraic equations related to budgeting, aligning with this standard.
CCSS.MATH.CONTENT.HSA.SSE.A.1.B
Secondary
Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)n as the product of P and a factor not depending on P.Reason: Students will need to interpret complex algebraic expressions and the effect of substituting variables, such as costs and totals.

Entry Events

Events that will be used to introduce the project to students

The Mysterious Budget Puzzle

The event kicks off with a surprise package delivered to the classroom, containing a letter from a secret entity (like 'The Budget Keeper') asking students for help to solve a mysterious budget puzzle.
