Identify four fourths as one whole

A whole partitioned into four equal parts has four fourths, with each part representing one fourth, or $1/4$ , of the whole; therefore, four copies of $1/4$ make $4/4=1$ whole. This relationship connects fraction notation, equal partitions of shapes or lengths, and points on a number line, while distinguishing fourths from unequal parts or parts of different-sized wholes.

Detailed Explanation: Identify four fourths as one whole

A fourth is one of four equal parts of a whole. Each part is written as $\frac14$ .

Example: A rectangle is split into 4 equal parts, and all 4 parts are shaded.

Count the equal parts: there are $4$ parts.
Each part is one fourth, or $\frac14$ .
Count the shaded fourths: there are $4$ of them.
Write this as:

\frac14+\frac14+\frac14+\frac14=\frac44

Four fourths make one whole:

\frac44=1

So, the entire rectangle is four fourths, which equals one whole. The parts must be equal in size for them to be fourths.
