Introduction (5 minutes)

Hook: The Perfect Smoothie

Imagine you're a master smoothie chef, and today you're competing in a “Smoothie Showdown.” Your goal is to create a delicious smoothie using specific ratios of ingredients. You have the following ingredients at your disposal:

• 2 cups of strawberries
• 3 cups of bananas
• 1 cup of yogurt

But there's a twist! The judges want every smoothie to maintain a perfect balance. If you want to make 3 smoothies, how many cups of each ingredient will you need?

Activity Setup

1. Group Discussion (2 minutes)

   • Ask students: "What do you think a ratio represents? How do ratios help us in the kitchen?"
   • Encourage students to share their thoughts about how different ingredient amounts can create different smoothie textures and flavors.

2. Visual Aid:

   • Display images of various fruits and smoothies on the board or a screen to spark interest.
   • Use visuals of smoothies to illustrate how the ratios might change with different flavors, colors, and textures.

Transition into Lesson Focus

After the discussion, explain to students that today they will explore the concept of ratios in-depth. They will learn how to calculate and compare ratios and apply their knowledge to create their own smoothie recipes.

Key Question for the Lesson:

• "If you double your recipe, how will your ratios change? Can you maintain the same delicious flavor?"

Conclusion of Introduction

By connecting the mathematical concept of ratios to creating a tasty smoothie, students will see the practical applications of ratios in everyday life. Let’s dive in and start mixing those ratios!
