Compare Simple Fractions

Compare Simple Fractions

What students learn

Students learn how to compare simple fractions when the parts are easy to line up. Start with Compare Fractions: Same Denominator, Bigger Numerator Means More so students can see that the bigger numerator means more equal parts.

Why it matters

Comparing fractions helps students reason about amount, not just symbols. It also prepares them to use number lines as a measurement tool, where location tells which fraction is greater. Compare Fractions: Same Numerator, Smaller Pieces Mean Less shows why the same numerator can still name different amounts.

Learn the idea

When the denominator is the same, compare the numerators. When the numerator is the same, compare the size of the parts. Then use Compare Fractions: Order Simple Fractions on a Number Line to place fractions from least to greatest and check the order visually.

Try it

Write 1/2 and 2/2, 2/3 and 3/3, and 1/4 and 1/3. Ask the student which fraction is larger in each pair and why. Then draw a number line and ask them to place the fractions in order.

Parent guide

Ask the child to say the rule before giving the answer: same denominator, compare numerators; same numerator, compare part size; then check the number line. If they guess, bring them back to the picture and have them point to the fraction that uses more of the whole.
