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:
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.
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
Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 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."*
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.
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?*
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*.
