Lesson Plan
Fraction Foundations Quick Guide
By the end of this 15-minute individual session, the 5th-grade student will be able to identify, represent, and solve real-world fraction problems, specifically those involving fair sharing scenarios like dividing a pizza, by visually and numerically manipulating fractional parts.
Understanding fractions is a fundamental skill for everyday life, from cooking to budgeting. This lesson makes abstract fraction concepts tangible and engaging through a relatable scenario like sharing pizza, helping the student build a strong foundation for future math concepts.

Materials
Prep
Review Materials
5 minutes
- Review the Fraction Foundations Quick Guide to understand the lesson flow and objectives.
* Familiarize yourself with the Pizza Party Fractions Visuals to be ready to present them.
* Print or prepare the digital version of the Slice and Share Challenges worksheet.
* Have the Pizza Problem Solutions ready for review after the student completes the worksheet, but do not provide it to the student beforehand.
* Prepare a whiteboard or scratch paper for additional visual aids if needed.
* Ensure the student has access to a pencil/pen and paper or a digital writing tool for the worksheet.
Step 1
Introduction: Pizza Predicament (2 minutes)
2 minutes
- Engage: Begin by asking the student, "Have you ever had to share a pizza with friends or family? How did you make sure everyone got a fair slice?"
* Connect: Introduce the idea that sharing fairly often involves fractions. Explain that today, we're going to become 'pizza-slicing experts' to master fractions.
* Objective: Briefly state the lesson's objective: to understand and use fractions to solve real-world sharing problems. (Refer to Pizza Party Fractions Visuals Slide 1)
Step 2
Fraction Foundations & Visuals (5 minutes)
5 minutes
- Introduce: Use the Pizza Party Fractions Visuals (Slides 2-4) to introduce or review basic fraction concepts:
* What is a fraction? (Part of a whole)
* Numerator (how many parts we have)
* Denominator (how many total equal parts)
* Demonstrate: Use the pizza examples on the slides to show how a whole pizza can be divided into halves, thirds, and quarters. Ask guiding questions: "If we divide this pizza for 4 friends, how many slices does each person get? What fraction of the pizza is that?"
* Interactive Practice: Ask the student to draw their own pizza and divide it into a specific number of equal parts (e.g., 6 slices). Ask them to shade in a certain fraction (e.g., 2/6).
Step 3
Slice and Share Challenges (6 minutes)
6 minutes
- Transition: Explain that it's time to apply our pizza-slicing skills to some challenges. Distribute or present the Slice and Share Challenges worksheet.
* Guided Practice: Work through the first problem or two together, ensuring the student understands the instructions and how to approach the problems. Emphasize drawing or visualizing the pizza as a helpful strategy.
* Independent Work: Allow the student to work independently on the remaining problems on the worksheet. Circulate and provide support as needed, asking questions to prompt their thinking rather than giving direct answers. (e.g., "How many equal parts are in the whole pizza for this problem?")
Step 4
Review and Reflect (2 minutes)
2 minutes
- Review: Once the student has completed the Slice and Share Challenges or when time is up, review the answers together using the Pizza Problem Solutions. Discuss any misconceptions or difficulties.
* Reinforce: Ask the student to summarize what they learned about fractions and sharing fairly. "What was the trickiest part of slicing the pizza fairly? What was the easiest?"
* Extend (Optional): If time allows, pose a quick challenge: "What if we had 3 pizzas and 4 friends? How could we share those fairly?"

Slide Deck
Can You Slice a Pizza Fairly for Everyone?
Ever had to share a pizza?
- How did you make sure everyone got a fair slice?
- Sometimes, sharing means using fractions!
Welcome the student and kick off the lesson with a fun, relatable question about sharing food. Set the stage for why fractions are important.
What is a Fraction, Anyway?
It's a way to show parts of a whole!
- Imagine a whole pizza.
- Before you cut it, it's just 1 whole!
Introduce the basic concept of a fraction: a part of a whole. Use the visual of a whole pizza before it's cut.
Meet the Numerator & Denominator
The two important numbers in a fraction:
- Numerator (Top Number): How many pieces you have or are talking about.
- Denominator (Bottom Number): How many equal pieces the whole is divided into.
Example: If you eat 1 slice of a pizza cut into 4 equal slices, you ate 1/4 of the pizza.
Explain the numerator and denominator using a simple pizza example. Emphasize that the parts must be equal.
Pizza Fraction Examples
Let's see some pizzas sliced up!
- Half (1/2): A pizza cut into 2 equal parts.
- Quarter (1/4): A pizza cut into 4 equal parts.
- Third (1/3): A pizza cut into 3 equal parts.
Think: How would you show 2/3 of a pizza?
Provide visual examples of pizzas divided into different equal parts (halves, quarters, thirds) to reinforce understanding. Ask the student to identify fractions.
Your Turn: Slice & Share Challenges!
Time to become a master pizza divider!
- You'll get a worksheet with some tasty challenges.
- Remember to draw pictures if it helps you visualize the fractions!
- Think about the whole and the equal parts.
Transition to the worksheet, explaining that it's time to put their new fraction skills to the test with real-world pizza problems.

Answer Key
Pizza Problem Solutions
Here are the step-by-step solutions for the Slice and Share Challenges. Encourage the student to explain their own reasoning before revealing the answer.
Challenge 1: The Classic Margherita
There is one whole Margherita pizza. You and 3 friends want to share it equally. How much of the pizza does each person get?
- Thought Process:
- There is 1 whole pizza.
- You + 3 friends = 4 people in total.
- To share equally, the pizza needs to be cut into 4 equal slices.
- Each person gets 1 out of 4 slices.
- Total friends: 4
- How many equal slices will you cut? 4
- What fraction of the pizza does each person get? 1/4
Challenge 2: Pepperoni Perfection
A large pepperoni pizza is cut into 8 equal slices. Your little brother eats 3 of those slices. What fraction of the pizza did your brother eat? What fraction is left?
- Thought Process:
- The whole pizza has 8 equal slices, so the denominator is 8.
- Your brother ate 3 slices, so the numerator for slices eaten is 3.
- To find the fraction left, subtract the eaten slices from the total slices: 8 - 3 = 5 slices left.
- Total slices: 8
- Slices eaten by brother: 3
- Fraction eaten: 3/8
- Fraction left: 5/8
Challenge 3: Veggie Delight Dilemma
You have a veggie pizza cut into 6 equal slices. You eat 1 slice, and your mom eats 2 slices. What fraction of the pizza did you and your mom eat together? What fraction is still available?
- Thought Process:
- The whole pizza has 6 equal slices, so the denominator is 6.
- You ate 1 slice and mom ate 2 slices, so together you ate 1 + 2 = 3 slices.
- To find the fraction available, subtract the eaten slices from the total: 6 - 3 = 3 slices left.
- Total slices: 6
- Slices you ate: 1
- Slices mom ate: 2
- Fraction eaten together: 3/6 (or 1/2)
- Fraction available: 3/6 (or 1/2)
Challenge 4: The Half-and-Half Pizza
A pizza is half cheese and half mushroom. If the whole pizza is cut into 10 equal slices, how many slices are cheese? What fraction of the pizza is mushroom?
- Thought Process:
- The whole pizza has 10 equal slices.
