### Activity Description

This activity aims to ensure students comprehend the concept of unit rates and their significance in comparing the cost of products, which is a fundamental skill in practical mathematics.

Storyline: You are planning a big family barbecue and need to buy ingredients. There are three stores from which you can purchase, "Farm Fresh", "Market Bargain", and "Quality Stores". You're working with a budget, and your objective is to locate the most cost-effective store for each ingredient.

Following are the ingredients to be purchased:

1. Hot Dog Buns
2. Hamburgers
3. Lettuce
4. Ketchup
5. Potato Chips
6. Soda
7. Ice Cream

By placing mathematical concepts within the real-world context of planning a family event, students will see the direct relevance of math in everyday decision-making.

This worksheet is a classroom-ready interactive digital worksheet that needs a few clicks to assign to your classroom. The worksheet is auto-scored, teachers just need to open the real-time console and monitor the student progress.

### Learning Objective

Students will understand the concept of unit rates, fractions, and ratios, apply mathematical concepts in real-world scenarios, develop budgeting skills, and hone their problem-solving abilities by comparing unit rates across different stores to identify the most cost-effective options for each ingredient

### Common Core: MATH

Ratios & Proportions

Understand the concept of a unit rate a/b associated with a ratio a:b with b &ne; 0, and use rate language in the context of a ratio relationship. *For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid \$75 for 15 hamburgers, which is a rate of \$5 per hamburger."*

Ratios & Proportions

Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

Ratios & Proportions

Solve unit rate problems including those involving unit pricing and constant speed. *For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?*

Ratios & Proportions

Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. *For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction ^1/2/1/4 miles per hour, equivalently 2 miles per hour*.
