Fraction Multiplier
Master Multiplying Fractions by Whole Numbers
🧬 Welcome to the Lab
Enter the Fraction Multiplier laboratory, where Year 5 students learn to multiply proper fractions and mixed numbers by whole numbers, supported by visual models and diagrams.
By "cloning" fraction specimens, students develop a concrete understanding of fraction multiplication as repeated addition.
🎮 How to Play
- Read the Problem: See the fraction and whole number multiplier
- Study the Model: Visual bars show the repeated groups
- Calculate: Multiply numerator by whole number, keep denominator
- Simplify: Reduce to lowest terms if needed
- Activate Cloning: Submit and earn coins!

This game addresses the National Curriculum objective:
"Multiply proper fractions and mixed numbers by whole numbers, supported by materials and diagrams."
🧠Multiplication Methods
Proper Fractions
Multiply the numerator, keep the denominator:
3 × 2/5 = (3 × 2)/5 = 6/5 = 1 ⅕
4 × 3/8 = (4 × 3)/8 = 12/8 = 3/2 = 1 ½
Mixed Numbers
Convert to improper first, then multiply:
2 × 1 ¾ = 2 × 7/4 = 14/4 = 3 ½
3 × 2 ⅓ = 3 × 7/3 = 21/3 = 7
Visual Understanding
Think of multiplication as repeated addition:
3 × 2/5 = 2/5 + 2/5 + 2/5 = 6/5
The visual model shows this clearly with repeated fraction bars!
💡 Lab Tips
- Use the Model: Count the shaded parts to verify your answer
- Convert Mixed Numbers: Always convert to improper fractions first
- Simplify: Check if your answer can be reduced
- Check with Division: Divide your answer by the multiplier to get back to the original
