The idea

Start with one whole shape or object and split it into equal-sized parts.

Step by step
  1. Start with one whole shape or object and split it into equal-sized parts.
  2. Two equal parts are halves; four equal parts are quarters or fourths.
  3. Check that all parts together make the original whole. Unequal parts are not halves or quarters.

Example
