Same bottom number: the bigger top is more. Same top number: a bigger bottom means smaller pieces, so less. Equal fractions cover the same amount of the same whole.

Watch for: Thinking 1/8 is more than 1/4 because 8 is more than 4. Comparing fractions of wholes that aren't the same size. Thinking 6/6 is more than 1.
At home: Fold two same-sized paper strips, one into halves and one into fourths, and hold them together: 1/2 and 2/4 line up.
