    Original problem:

    Using description of the proportional relationship and the table, identify the constant of proportionality and then write the equation to represent the situation in the table.

    Alison earned $24 by stocking shelves at the grocery store for 3 hours.

    Time (h), x 1 2 3 6

    Total Pay ($), y 8 16 24 48

    1. Spark curiosity with a photo of a girl stocking shelves

    What do you notice? What do you wonder? Discuss

    2. Share that the girl, Alison, made $24 for the time she worked

    Estimate too high, too low, and best guess. Discuss

    3. Show the table and ask students to check their estimates and discuss how they know if their estimate is correct.

    4. Follow up with prompt to identify the constant of proportionality and write an equation to represent the situation.

    I am going to try this with my seventh graders when we head back to school at the end of the month.
