A whole can be partitioned into two equal-sized parts, each called one half; the two halves together are exactly one whole, whether represented by a shape, object, or length. The understanding depends on equality of area, amount, or length—not merely on having two pieces—and provides a foundation for interpreting simple fractions and partitioning wholes into equal parts.

Detailed Explanation: Identify two halves as one whole
A whole is one complete thing. If the whole is split into 2 equal parts, each part is called one half.
Example: A strip is 8 cubes long. It is split into 2 equal pieces.
-
Count the cubes in each piece.
Each piece has 4 cubes. -
Check that the pieces are equal.
Both pieces are the same length: 4 cubes. -
Put the two pieces together.
The two equal pieces make the entire 8-cube strip, so each piece is one half. Together, the two halves make one whole.
