Why This Matters
Understanding ratios and unit rates helps students make sense of prices, speeds, and other comparisons in their daily lives, like choosing the best deal at the grocery store or understanding fuel efficiency.
Learning Objective
Students will understand, identify, and calculate ratios, rates, and unit rates from real-world scenarios, specifically focusing on proportional relationships involving pizza delivery pricing.

Which one would you choose? Why?
What's a Ratio?
A ratio compares two quantities.
1
It can be written as: a to b, a:b, or a/b
2
It shows the relationship between two numbers.
Example: Pizza Palace
Slices to Cost Ratio
12 slices : $24
Cost to Slices Ratio
$24 : 12 slices
What's a Rate?
A rate is a special ratio that compares two quantities with different units.
Pizza Rate
$24 for 12 slices
Comparing Dollars ($) to Slices!
Miles per Hour
Distance & Time
Words per Minute
Text & Time
Dollars per Pound
Cost & Weight
The "Unit" in Unit Rate!
A unit rate is a rate where the second quantity is exactly 1.
The Secret Formula:
Divide First Qty
Let's Calculate
Pizza Palace: $24 for 12 slices
$24 ÷ 12
Unit Rate (Cost per slice)
$2.00 / slice
Guided Practice: Super Slice

Teacher Resource
1
Warm-Up: Pizza Predicament (5 min)
Teacher distributes the warm-up handout. Allow 2 minutes for silent thinking.
Teacher: "Good morning, future math chefs! Today, we're going to dive into a topic that helps us make smart decisions every single day, especially when it comes to our favorite foods. Let's start with a warm-up called Warm-Up: Pizza Predicament . Please take one and work independently for about two minutes. Think about the pizza problem and what you would choose."
After 2 minutes...
Teacher: "Alright, let's talk pizza! Who can share their thoughts on the Pizza Predicament? Which pizza would you choose and why? Don't worry about being perfectly 'mathy' yet, just tell me your initial ideas."
Tip: Listen for keywords like 'cheaper,' 'more slices,' or 'better deal' to bridge to the math definitions.

Introduction: Pizza Delivery Hook (10 min)
Display Slide 1: Welcome to Pizza Ratios!
Teacher: "Welcome to Pizza Ratios! Today we're going to become experts at 'slicing and dicing' numbers to get the best deals and understand comparisons. Our goal is to understand and calculate ratios, rates, and unit rates."
Display Slide 2: The Great Pizza Debate!
Teacher: "So, you've seen these two pizza deals. How do you really figure out which one is the better deal? What math tools could we use to compare them fairly? Turn and talk to your partner for 30 seconds."
Teacher: "Excellent discussions! Many of you are hinting at some very important math concepts. Today, we're going to officially learn about ratios, rates, and unit rates."
Display Slide 3: What's a Ratio? (Reference Anchor Chart)
Teacher: "First up, a ratio . A ratio is simply a way to compare two quantities. Look at our Pizza Palace deal: 12 slices for $24. We can write this as 12 slices to $24, or 12:24, or even 12/24. What are the two quantities we are comparing here?"
Wait for student response: "Slices and Cost"
Display Slide 4: What's a Rate?
Teacher: "Now, a rate is a special kind of ratio. It compares two quantities that have different units . In our pizza example, we're comparing money ($) to slices. Can anyone think of another example of a rate from everyday life?"
Wait for responses like: "miles per hour", "words per minute"
