Partitioning Circles And Rectangles (2nd Grade Intro To Fractions)
A Note For Parents: In second grade, students focus on equipartitioning and develop an understanding of identifying whether or not a shape has been partitioned into equal shares and how to partition shapes into equal shares themselves. Students will partition circles and rectangles into 2, 3 or 4 equal shares (regions). Students should also work with the vocabulary terms halves, thirds, fourths, half of, third of, fourth of, and quarter of. While students are working on this standard, they should make the connection that a “whole” is composed of two halves, three thirds, or four fourths. This unit also addresses the idea that equal shares of identical wholes may not have the same shape.
It is important for students to understand that fractional parts may not be symmetrical. The only criterion for equivalent fractions is that the area is equal. It is important for students to see circles and rectangles partitioned in multiple ways so they learn to recognize that equal shares can be different shapes within the same whole.
Here are examples of equally dividing (partitioning) three same sized rectangles into halves in three different ways.
