    • Varied language that describes multiplicative comparisons.

    Skills

    Students are able to:
    • Interpret equations for multiplicative comparisons.
    • Write equations for multiplicative comparisons.

    Understanding

    Students understand that:
    • Multiplicative comparisons relate the size of two quantities and a scale factor.
    • Factors in multiplication problems have different roles from each other in the context of comparison problems.
    • Explanations and drawings show ways multiplicative comparisons are similar to and different from equal groups and arrays.

    Learning Objectives

    Learning Objectives

    The student will be able to use verbal statements to describe multiplicative comparisons and write a multiplication equation that represents the statement.

    Activity Details

    1. Pass out the Picture This! worksheet.
    2. Read the comparison statement aloud to the students.
    3. Ask students to work independently or in partners to complete the task.
    4. Allow students to share their answers or take this up as an Exit Slip for formative assessment.
    Assessment Strategies

    Assessment Strategies

    Check student work at the conclusion of the activity to assess their understanding. You can use the following guidelines to ensure students meet the learning objective.

    Check that the student:

    1. drew a correct picture.
    2. wrote a correct multiplicative comparison statement.
    3. wrote a correct multiplication equation.

    Variation Tips

    This task can be used as a stand-alone activity or in conjunction with Comparing Amounts (before activity) and The Food Drive (during activity).
