This is a simulation, not a quiz. You answer by trying things and watching what happens.

Our question

If 2 of 5 pieces are shaded, is it always 2/5?

Getting the simulation ready…

  1. 1Build or change something
  2. 2Say what will happen, then run it
  3. 3Finish: say what you found
What counts as evidence
  • A bar cut into 5 pieces of different sizes, with 2 shaded.
  • The shaded part lined up with 5 equal fifths.
  • A conclusion must address the Fraction Forge question.
