Partition Shapes (Grade 3)
Videos 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.

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.
