Fractions: Decompose and Recompose

What if we took a fraction apart, then took those pieces apart, then recombined them, and then recombined those, arriving back to the original fraction?

Numerator or Denominator: Which has more power in a fraction?

What do you do with students who already get their fraction operations? Give them a contrived project about recipes or pizza slices? Make them solve annoyingly hard practice problems? Please. Here, we get students thinking in a whole new way, pondering which has more power, the numerator or denominator.

A Grid-Based Fraction Project

You’ve got 60 spaces on a grid to create an amusement park, a house, a farm, or whatever you’d like. Divide it into seven pieces, order it by size, combine into two halves, and more in this fraction project.
