Identify two halves as one whole

A half is one of two equal shares of the same whole; the two equal shares together make exactly one whole, represented as $2/2 = 1$ . This understanding applies to partitioned shapes, lengths, or collections, and distinguishes halves from two unequal parts; it provides a foundation for comparing fractions and composing fractions into wholes.

Detailed Explanation: Identify two halves as one whole

A half is one of 2 equal parts of the same whole.

If we put the two equal halves back together, we have the entire whole:

\frac{1}{2}+\frac{1}{2}=\frac{2}{2}=1

Example: A rectangle is divided into 2 equal parts. Both parts are shaded. What fraction of the rectangle is shaded?

The rectangle is split into 2 equal parts.
Each part is one half, or $\frac{1}{2}$ .
Both halves are shaded, so count the shaded parts: $2$ .
There are $2$ equal parts in all, so the fraction is $\frac{2}{2}$ .
Two halves make one whole:

\frac{2}{2}=1

So, the shaded amount is one whole rectangle. Remember: the parts must be equal for them to be halves.
