Share an object into halves

Understanding halves means partitioning one whole object into two equal parts, so each part has the same size, area, or amount and is called one-half (½) of the whole. The two halves together make the original whole; unequal pieces are not halves, even if there are two of them. This establishes the foundation for comparing, naming, and combining fractional parts.

Detailed Explanation: Share an object into halves

To share one whole object into halves, split it into two equal parts. Each equal part is called one-half, written 12\frac{1}{2}.

Example: Share one rectangular sandwich between two children.

  1. Start with the whole sandwich.
  2. Find the middle of the sandwich.
  3. Cut straight down the middle.
  4. Check that both pieces are the same size.

Now there are two equal pieces. Each piece is 12\frac{1}{2} of the sandwich.

12+12=1 whole\frac{1}{2}+\frac{1}{2}=1\text{ whole}

If one piece were bigger than the other, the pieces would not be halves because they would not be equal.
