Recognize fourths in different shapes

A fourth is one of four equal-sized parts of a whole shape, and the four parts together make the whole; it can be represented as 14\frac14. The parts may differ in orientation or appearance, and the whole may be divided in varied ways, but four unequal pieces are not fourths—this understanding establishes unit fractions and equal sharing.

Detailed Explanation: Recognize fourths in different shapes

A fourth is one of 4 equal-sized parts of a whole. We write one fourth as 14\frac14.

Imagine a square with both diagonals drawn:

  1. The lines split the square into 4 pieces.
  2. Each piece is the same size, even though the pieces point in different directions.
  3. The 4 pieces fit together to make the whole square.
  4. So each piece is a fourth, or 14\frac14, of the square.

Remember: The pieces do not have to look exactly the same. They must be equal in size, and there must be 4 parts altogether.
