Pacing
One 45–60 minute class period. Optional two-day version: Day 1 = Introduction through Vocabulary and game play; Day 2 = Self-Check, Reflection, and save deliverable. Students who finish early can attempt the extension challenge in the differentiation notes below.
Grouping Suggestion
Best as individual work with a brief pair-share after Step 3 (reviewing the keep–change–flip rule with a partner example). Partners can check each other's scratch work before submitting the final digital check.
Differentiation
Support: Provide a visual fraction bar or number line model. Have students act out division with manipulatives (e.g., "I have 3/4 of a cup — how many 1/8-cup scoops fit?"). Accept equivalent answers expressed as mixed numbers (e.g., 4 and 3/5 for 23/5).
Challenge / Extension: Ask students to create their own bakery word problem using fractions, solve it two ways (keep–change–flip and a diagram), and explain which method they prefer and why. Extend to dividing mixed numbers.
ESOL / Language Supports
Pre-teach vocabulary: fraction, reciprocal, dividend, divisor, quotient, equal groups. Use the Vocabulary box on the page and add translated word walls if available.
Encourage students to draw a picture model alongside the numerical computation.
The bakery context is intentionally concrete — reinforce the meaning of "how many groups fit?" before introducing the algorithm.
Pair students strategically for vocabulary review. Allow first-language discussion of strategy before writing in English.
1. Introduction
Welcome to the Fraction Kitchen! 🧁 A bakery gets big orders.
To share the dough, you must divide fractions.
Example: A baker has 3/4 cup of jam. Each tart needs 1/8 cup.
How many tarts can the baker fill? In this WebQuest you will learn to divide fractions and answer real bakery questions.
2. Task
By the end, you will:
Explain what dividing a fraction by a fraction means in a real situation.
Show how to divide a fraction by a fraction using the keep, change, flip rule (multiply by the reciprocal).

6. Interactive Self-Check
Try each question, then click Check to see instant feedback. Write fractions like 3/4. Complete all 5, then click Grade my answers at the bottom to record your score.
Use keep–change–flip: 1/2 × 4/1 = ?
Turn the fraction upside down.
3. To divide fractions, what do you do first?
Keep 3/4, change to ×, flip 1/8 to 8/1: 3/4 × 8/1 = 24/4 = ?
2/3 × 6/1 = 12/3 = ?

🔑 Teacher Answer Key (click to expand)
Q1 — 1/2 ÷ 1/4: 1/2 × 4/1 = 4/2 = 2. (Two 1/4-cups fit in 1/2 cup.)
Q2 — Reciprocal of 2/3: Flip numerator and denominator → 3/2. (Also acceptable: 1½ or 1.5, but fraction form preferred.)
Q3 — First step to divide fractions:B. Keep the first fraction, change ÷ to ×, and flip (take the reciprocal of) the second fraction.
Sample student reflection: "Dividing fractions is the same as multiplying by the reciprocal. I used keep–change–flip every time and it made the problems easier because I already know how to multiply fractions."
7. Conclusion
Great work, baker! You learned to divide fractions with keep–change–flip.
Now you can share dough, jam, and batter into equal parts in any real kitchen.
Save your results and turn them in.
8. Reflection
Answer this in 2–3 sentences in the box below:
Where in real life might you need to divide a fraction by a fraction? Describe a situation and explain what the answer (quotient) would mean.
