Fraction Forge

Your child feeds friendly forge golems by building shapes from bar and pie pieces. Fractions start as pieces you can see, cut and join. The numbers come later.

How it plays

What your child does

  1. Drag pieces into place to fill a shape.
  2. Cut a piece into halves, thirds or quarters, or join pieces together.
  3. A piece that does not fit just wobbles. After two tries the buddy shows where the right one goes.

Four forges

Ember’s Anvil

Parts of a whole, with no numbers anywhere.

Cobble’s Scales

Compare pieces on a scale, now with fraction labels.

Mossy’s Twin Molds

Bolt’s Melting Pot

For grown-ups

Good to know

  • Each forge has 15 puzzles and opens after the one before.
  • The home screen shows Fraction Forge to children aged 8 to 10. You can turn it on for any child in the Parent Zone.
  • The game saves itself, so your child can stop at any time and pick up where they left off.
