Comparing Fractions with Like Numerators or Denominators

Two visual problems give mathematicians a chance to compare fractions with like denominators. They examine two pairs of shapes with portions filled in, adding the greater than, less than, or equal to symbol between each. The shape pairs are segmented into an equal number of shapes to make comparing easier. Because the answer is detailed below, this lends itself nicely to an all-class warm up. Cover up the answers until you've gotten answers from the class.
