Why I Built This Mixed Numbers to Improper Fractions Generator
Hi everyone, I'm Ronit Shill. I'm a Math Teacher and Coder who knows that fractions are the "make or break" topic for 5th graders. One of the most critical skills is converting mixed numbers (like 2 1/3) into improper fractions (like 7/3).
I noticed my students could draw mixed numbers fine, but when it came time to multiply or divide them, they got stuck. Why? Because you cannot easily multiply mixed numbers without converting them first! This tool creates endless practice problems to make that conversion automatic.
The "MAD" Method Strategy
In my classroom, we don't just memorize steps; we use the MAD method. It is the secret code to converting mixed numbers.
😠 The MAD Method
- M - Multiply: Multiply the whole number by the denominator ($2 \times 3 = 6$).
- A - Add: Add the numerator to that product ($6 + 1 = 7$).
- D - Denominator: The denominator stays the same ($/3$).
Result: 7/3
How to Use This Generator
1. Level 1: Easy Mode (Concept Building)
Start with Easy difficulty. This keeps the whole numbers small (1-5) and denominators simple (2-6). This allows students to do the multiplication and addition in their heads, building confidence with the MAD process.
2. Level 2: Hard Mode (Fluency)
Switch to Hard to introduce larger whole numbers and denominators like 8, 9, or 12. This requires stronger multiplication fact recall (e.g., $9 \times 7$) and helps students realize that the process works for any size number.
Common Student Hurdles
Here are the traps students fall into, so you can help them avoid them:
Adding Instead of Multiplying
In $2 \frac{1}{3}$, students sometimes add $2+3=5$ instead of multiplying. Remind them: "The whole number tells you how many full groups of the denominator you have."
Forgetting the Numerator
They do the multiplication ($2 \times 3 = 6$) and write 6/3. They forget the "A" in MAD—Adding the original numerator!

Future Updates
I'm working on adding a "Visual Mode" where the mixed numbers are represented by colored pie charts to help visual learners see the "wholes" and "parts."
Don't get MAD, get even (with math)!
