Videos, examples, solutions, and lessons to help Grade 3 students learn to partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.

Common Core: 3.G.2

Suggested Learning Targets

  • I can partition shapes into equal parts.
  • I can explain any unit fraction as one part of a whole divided into equal parts.
3 G 2 Lesson 1
In this lesson, you will learn how to partition (divide) into equal parts with equal areas.

3 G 2 Lesson 2

This activity is obtained from Howard County Public School System

Materials and Directions:

  • Give each student a fraction (i.e. ¼, ½) and some colored squares (i.e. color tiles). 
  • Have students create their fraction as a fraction bar using the colored squares.
  • Then have students explain their fraction using the characteristics of fractions (equal area, number of total squares (denominator), number of certain colored squares (numerator).


  • Observe students making fraction bars.
  • Do students have an understanding that fractions have equal areas?
  • Do students recognize the characteristics of fractions?
  • Explanations can be oral or in written form.
