    Answer:

    Step-by-step explanation:

    “Suppose we covered a large section of wall with chalkboard paint.

    How would we find the area we wanted to paint?” Your student might

    answer, “Measure how high and how far across, then multiply.” Then

    ask, “If one quart of paint covers 65 square feet of wall, how many

    quarts would we need to paint the blackboard section with 2 coats?”

    Your student would multiply the area by 2 and compare that number

    to 65. For example, a blackboard 8 feet wide and 5 feet high is

    40 square feet, and 2 coats would be 80 square feet. One can of

    paint would not be enough.

    • “Suppose we put new carpet in your bedroom. How many square feet

    would we need to buy? How would we figure this out?” Your student

    might answer, “Measure each wall of the room and multiply. If the

    room isn’t a perfect rectangle, divide it into smaller pieces that are

    easier to work with.”

    Getting your student involved with home projects develops useful skills for

    helping around the house, finding a part-time job, and eventually being

    responsible for his or her own home.

    Enjoy your time working together!
