Step 1: Let's Learn

Read it, or press Listen and follow the words.

Cut a whole into 4 equal shares. Each one is a fourth.

Fourth is one of four equal shares. It is also called a quarter.

More shares, smaller pieces

A fourth is smaller than a half. More people means less each.

Four fourths make one whole, just as two halves do.

More pieces means smaller pieces

A quarter is smaller than a half, even though four is bigger than two. Cutting the same whole into more parts makes each one less.

Two names, one thing

Fourth and quarter mean the same. Quarter is the everyday word, fourth is the counting word.

Step 2: Try It Yourself

Change the shares from 2 to 4 and watch the pieces shrink.

Set it to 4 shares. Shade one fourth.

The whole is cut into 4 equal shares, called fourths.
