    First, I feel stupid asking this.:eek:

    I gave Jeannie a math assessment today that consisted of 22 questions. How do I determine the worth of each of those questions, so that I can figure her score?

    Do you want a percentage score?

    Do you want all the questions to have the same weight?

    I would divide the number she got correct by 22 to give you a percent.

    Yep- all the questions have equal weight.

    Then 22 is 100%, which means score divided by 22 will give you the ratio she got correct, and multiplying that percentage times 100 will give you a percentage score.

    Alternatively, each question is worth 4.5454 points, roughly. Multiplying this by the number she got correct should give you a similar score (okay, I rounded to the nearest ten thousandth).

    For example, suppose she got 16 correct. 16 divided by 22 is .7272 (repeating), or roughly 73%. 4.5454 times 16 is 72.7264.

    Take the number she got correct. Divide by the total number. Make the answer a percentage and round it. (So if you get 0.9487 you would make that 95%)

    So if you missed 2 questions, that means you go 20 questions correct. 20 divided by 22 equals 0.9090, which translates to 90.90 percent. Round that to 91 percent.

    -0 22/22
    -1 21/22 95%
    -2 20/22 91%
    -3 19/22 86%
    -4 18/22 81%
    -5 17/22 77%

    and so on

    Okay, 3Sons- when did you put a nanny cam in our dining room?? Jeannie did get 16 of them right.

    Today I learned to not give tests on music class day, lol.

    We use a 3 2 1 scale at my school so I would do

    1-11 1 (below grade level)
    12-17 2 (basic level of understanding)
    18-22 3 (proficient)

    The easy grader can be picked up at any teacher supply store. It figures percentages for you using a slide system.

    They had an 'easy grader' knock off at my Dollar Store in the spring.

    Here's an online %age calculator: (although a regular calculator works just as well any day!!)

    becky- you'd type in 16 is what percentage of 22 and then hit calculate 'button'...72.727%
