Learning Activity

Can Fractions Be Equal?

Subject Area





This tool allows the participant to visually create two equivalent fractions based on the fraction provided. This can be used as an introduction since it allows you to determine your own fraction and construct models. You can also use it as a closing activity to check students understanding by asking them to construct a visual model.

    Mathematics (2019) Grade(s): 4

    Using area and length fraction models, explain why one fraction is equivalent to another, taking into account that the number and size of the parts differ even though the two fractions themselves are the same size.

    • Area model -Length model


    Students know:
    • Fractions can be equivalent even though the number of parts and size of the parts differ.
    • Two fractions are equivalent if they are at the same point on a number line or if they have the same area.


    Students are able to:
    • Use area and length fraction models to explain why fractions are equivalent.
    • Recognize and generate equivalent fractions.


    Students understand that:
    • equivalent fractions are fractions that represent equal value.


    Learning Objectives

    Learning Objectives

    Students will create equivalent fractions through a visual model.

    Activity Details

    The students will use Illuminations: Equivalent Fractions website to construct equivalent fraction models. These models that they construct would be used as an exit slip to determine if students can create their own models.

    Assessment Strategies

    Assessment Strategies

    To determine if students can construct equivalent fractions they could take a screenshot of their work and email it to the teacher as an exit slip. The teacher can also observe the models students make.
