CCSS Math Standard: 5.NF.1

Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)

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.
