Unit Rates Unleashed: A Math Adventure!

Lesson Introduction

Welcome, mathematicians! Today, we’re embarking on a thrilling journey into the world of unit rates and ratios of fractions. Before we dive into the math, let's ignite our creative juices and think a bit outside the box.

The Challenge: The Great Snack Off!

Imagine this: You and your friends are at a Sea Breeze Adventure Park, where the smell of delicious snacks fills the air. Everyone is hungry, and you have a limited amount of money to spend on your favorite treats. Your mission? To figure out which snack gives you the best bang for your buck!

• Snack A: A bag of popcorn costs $3 for 4 cups.
• Snack B: A candy bar costs $2 for 3 pieces.
• Snack C: A smoothie costs $5 for 2 cups.

The Hook: Fraction Fun!

To fuel this competition, we must discover the unit rates of each snack using ratios of fractions. The key question of the day is: Which snack provides the best value?

Activity Time!

1. Group Discussion: Form small groups and discuss the importance of unit rates in everyday life. Why is it essential to know how much of something you are getting for your money?

2. Exploration with Fractions: As a group, calculate the unit rate for each snack. How do we express these quantities as fractions? For example, how do we find the cost per cup for the popcorn?

3. Present Your Findings: Each group will present their findings and reasoning. Which snack is the winner, and why?
