Decimal Deals: Shopping Spree Simulation

Grade 7Math1 days

In the Decimal Deals project, 7th-grade students engage in a virtual shopping spree to apply and master the multiplication of decimals while managing a budget. The project encourages students to use their mathematical skills in real-world scenarios by creating budgets, calculating costs, and employing estimation strategies in a virtual marketplace. Through this simulation, students enhance their understanding of decimal operations and budgeting, supported by an engaging game-show themed entry event 'The Price is Right: Decimal Edition'. The activities align with Common Core Standards for rational numbers and equations, setting the foundation for practical mathematical applications. This project emphasizes accuracy, strategic planning, and problem-solving, culminating in a reflection on their learning experiences.

Common Core Standards

CCSS.MATH.CONTENT.7.NS.A.2

Primary

Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.Reason: The project involves multiplying decimals, which are a subset of rational numbers, making this standard highly relevant.

CCSS.MATH.CONTENT.7.NS.A.3

Primary

Solve real-world and mathematical problems involving the four operations with rational numbers.Reason: The project's context of a shopping spree simulates a real-world mathematical problem requiring the use of operations with rational numbers.

CCSS.MATH.CONTENT.7.EE.B.4

Supporting

Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.Reason: Although the main focus of the project is on decimals, using equations to manage budgets can provide deeper understanding.

Entry Events

Events that will be used to introduce the project to students

The Price is Right: Decimal Edition

Students participate in a live-action game show styled event where they 'shop' various virtual market items competing to come closest to an actual total without exceeding a given budget. This encourages competition while practicing decimal multiplication and addition skills in a fun environment.
