Fraction Factory

Drive the forklift, collect only the fraction parts that satisfy the machine plan, align beneath the correct department, and launch the completed crate.

Every department changes the math and machine: wholes, equivalence, addition, subtraction, multiplication, and division.

Start the factory, read the machine plan, and collect mathematically valid fraction parts.

How to play

Use arrows/WASD, touch-drag, mouse-drag, or the on-screen pad.
Collect fractions that satisfy the current machine rule; defective crates reduce accuracy.
When the load is complete, align beneath the glowing department and press Build.
Space/Enter builds, P pauses, and M mutes.
Each level changes both the machine and the fraction concept.

Knowledge check

1. Which fraction equals 1/2?

2. What is 1/4 + 1/2?

3. How many 1/8 groups fit in 3/4?

Learning outcomes

Compose and decompose a whole with unit fractions.
Recognize equivalent fractions using scaling and visual models.
Add and subtract fractions with unlike denominators.
Use common denominators and simplify results.
Model fraction multiplication as an overlapping area.
Interpret fraction division as the number of groups that fit.

Key gameplay concept: machines run only when fraction size—not merely numerator or denominator—satisfies the plan.
