Fraction Galaxy

Move through a fraction puzzle galaxy by solving math gates and pushing blocks into the right places.

Skill: Fractions in context

Fraction Galaxy turns fraction questions into keys: each gate only opens when the fraction problem in front of it is solved, and the rooms in between ask you to push blocks into place. The creator labels it a demo, so treat it as a short challenge rather than a full course.

It works best for learners who already know what a fraction is and can compare or add simple fractions. Have paper ready; working fractions out in your head while steering a character is harder than it looks.

How to play

  1. Click the computer icon to choose keyboard controls, then press any key on the title screen.
  2. On the level selector (the bobbing 01), press Space to start the highlighted level. Mouse clicks do not start a level.
  3. In a level, use the arrow keys to move and push blocks, following the on-screen prompts.
  4. If keys do nothing, click once inside the game frame so it has keyboard focus, then try again.

What it practises

  • Reading fractions written as a/b and connecting them to "a parts out of b equal parts".
  • Comparing fractions with different denominators.
  • Planning a route before moving, because pushed blocks cannot always be pulled back.

A quick fraction warm-up before playing

  1. Draw a bar split into 4 equal parts and shade 3. Say it as "three quarters".
  2. Draw a second bar the same length split into 8 parts and shade until it matches. You need 6: three quarters equals six eighths.
  3. Use the same idea when a gate asks you to compare fractions: make the bottom numbers match first.

For parents and teachers: If a child guesses at gates to get through faster, pause and work one problem on paper together. The block puzzles are a reward for getting the maths right.

Fraction Galaxy FAQ

Is Fraction Galaxy a full game or a demo?

The Scratch instructions label it as a demo and say it includes 10 levels plus 2 extra levels.

What does the player do in the levels?

The source instructions describe moving and pushing blocks around to unlock doors and move forward.

Can I use paper for the fraction problems?

Yes. The project description explicitly suggests using paper if fractions are difficult.
