• Fourth Grade "Thinkers"


    Mary knew report cards were going to be given out very soon and she was very worried about her grade in math. She knows that her test scores were 100, 50, 100, 96,89, and 45.

    Help Mary find the average of her test scores and her report card grade.

    For an A, her average has to be between 90 and 100.
    For a B, her average has to be between 80 and 89.
    For a C, her average has to be between 70 and 79.

    What grade could Mary expect on her report card?
