What is partitioning circles and rectangles? To understand the fractions, kids need to have a clear understanding of the shapes and how to partition them. The initial fraction lessons begin with partitioning shapes, which lays the foundation for the concept. It is best to start learning fractions with basic shapes such as circles and rectangles. Partitioning means separating something into different sections. Partitioning can be done in two ways, which include equal and unequal parts. In equal partition, each of the partitioned sections is identical to the other partitioned sections. When you place these partitioned sections on each other, they will exactly lay down and match the sections below them. When you partition a circle and a square in two halves, each partitioned half can be written as 1/2. When you equally partition a circle in 4 parts, each section can be written as 1/4. An unequal partition is where each partitioned section is of a different size; these sections, when placed on top of each other, will not match the sections below them. When the partitioned sections combine, they form a shape. These worksheets help students learn to break circles and rectangles into equal and unequal sub-shapes.
