TIMS Task

    1. 1, 2, 3, 4, 6, 9, 12, 18
    2. 93; Yes, 38 is a good number because there is only one factor that Maya can circle, 19.
    1. She can circle 19.
    2. Possible response: I think Maya should circle 39 because it would give her a lot of points but Luis would only be able to circle 13.
