Same size, different name.
The big ideaDifferent numbers can name the same size. Line the bars up and see where they end.

How it works

Different fractions can name the same size.

Line the bars up and see where they end.

2/8 is the same size as 1/4, and 4/4 is the same size as 1 whole.

2/8 is shaded
2/8 shaded.
1/4 is shaded
1/4 shaded: the same size.

Example 1: Are they the same?

  1. Are 4/4 and 3/4 the same size?
  2. 4/4 is a whole bar. 3/4 is not all of it.
  3. They end in different places.
  4. So the answer is No.

Example 2: Another name

  1. Write another name for 2/8.
  2. 2 of 8 equal parts is the same as 1 of 4.
  3. Each fourth is two eighths.
  4. So the answer is 1/4.

Example 3: A whole

  1. Write another name for 4/4.
  2. 4 of 4 equal parts is all of it.
  3. That is 1 whole, 1/1.
  4. So the answer is 1/1.
