Identify one fourth

A one-fourth is one of four equal-sized shares of a whole, written 14\frac{1}{4}, and can be identified in partitioned shapes such as circles and rectangles. The learner understands that the parts must have equal area, even when their shapes or orientations differ, and that four fourths make one whole; unequal parts are not fourths.

Detailed Explanation: Identify one fourth

A one-fourth means one of 4 equal parts. We write it as 14\frac{1}{4}.

Example: A rectangle is divided into 4 equal parts. One part is shaded.

  1. Count the parts: there are 44 parts.
  2. Check that the parts are equal in area. Each part is the same size.
  3. Count the shaded parts: there is 11 shaded part.
  4. So the shaded part is one-fourth, or 14\frac{1}{4}.

Remember: The parts may look different because they are turned or shaped differently, but they must cover the same amount of space. Four fourths make one whole: 44=1\frac{4}{4}=1.
