    They're giving you some of the factors for a number (in ascending order, it looks like) and you have to figure out the number and then list the rest of the factors.

    Remember that for any number, N, both 1 AND N are factors. So, looking at your first list, your number has 1 as a smallest factor and 12 as a biggest factor, so the number must be equal to 1 x 12 = 12.

    The factors of 12 are 1, 2, 3, 4, 6, 12 which accurately fills in the rest of your list.

    I'll leave the second one.

    Thumbs up Math Factor

    Mathnasium,
    Thank you very much. We finally figured out that the questions was asking for the factors of 12, however your description made it more clear.

    Fifth grade math can be a challenge. Can you recommend any on-line practice programs that might be good for a 5th grader. I found that my eldest, by the time she took the SSAT in 8th grade (the test required for private high school) we were ill prepared. Consequently we spent most of the summer and much of the year with a math tutor. I believe that because she did not learn what she was supposed to learn in 5th, 6th and 7th she struggled. I do not want to make that same mistake with my 10 year old 5th grader.

    Thanks,
    Math Mom
