Partitioning a two-dimensional shape into four equal parts means creating four regions with the same area, so each region represents one fourth (or one quarter) of the whole and four fourths make one whole. The parts need not be arranged in a particular orientation, but unequal areas do not represent fourths even if the regions look similar; this understanding is limited to simple shape partitions and unit fractions, not fraction operations or generalized fractional reasoning.
To partition a shape into four equal parts, split it so that all four parts have the same area.
Example: Partition a rectangle into four equal parts.

Each small rectangle is the same size, so each one is one fourth, written as , of the whole rectangle.
There are four fourths altogether:
So the rectangle has been partitioned into four equal parts.
