Points based grading

Hello All-

Question about point based grading. If you are grading according to points, how do you grade reading passages? For example, if a passage has 7 questions and you want each of your passages to count 20 points each, how would you do that?

I know it seems like a simple question but I really couldn't figure out how to make that work.


I appreciate your insight!

Brittany

Point-based grading

Why not have the passage be worth a total of 21 points with each question worth 3 points each?

If the students need a percentage, just get yourself an EZ-Grader. It's a slide rule-type of tool. I used the same one for almost all of my 37 years of teaching! I never had to worry about having a "friendly" number of questions in order to compute grades.

If I have designated each passage to be worth a specific amount of points...not sure how to swing that because each passage has a different amount of questions.

I think what you’re talking about is weighting. You would have to grade each passage separately and then give a total score.

You could make a simple proportion to find the equivalent score out of twenty. So if the student scores 6/7, figure out how much out of twenty it would equal (approx 17 points).

My easy grade pro program does this math automatically. I can input the score of the assignment, and designated a total point value I want the assignment to be worth. So technically it is weighting the grade.

not pretty outcome

in your calculator type: 20/7 = 2.857142857 (Yikes, but this is what each question is worth.

so if you leave that decimal of 2.857... in your calculator, then you multiply that by the number they got correct.

Example: I get 4 correct so 4 x 2.857142857 = 11 points (rounding) The reason I would keep the entire decimal in the calculator is the further you carry it out, the more accurate.
here is a rundown of points

# correct in first column with points earned (round to nearest whole) right beside it.

0 correct= 0 pts
1 correct = 3 pts
2 correct = 6 pts
3 correct = 9 pts
4 correct = 11 pts
5 correct = 14 pts
6 correct = 17 pts
7 correct = 20 pts

Can you put it in the grade book out of 100, instead of 20?

So if one reading passage has 7 questions and they get 6 right...6/7 = 0.857...so in the grade book they would get an 86/100.

Then if the next passage is out of 12 points and they get 9 right...9/12 = 0.75...so in the grade book they would get a 75/100.

I make almost everything out of 100. That way it's easy to grade differentiated work. It's not always perfect, but it makes things super easy...and easy for parents to understand.

Equivalent fraction

Find the percentage correct by dividing the student's correct number by 7. Then multiply that percentage by 20. That will give you the total points to enter into the grade book.

Example:
6 out 7 correct= 86%
Take .86 X 20 which equals 17.2

That is the equivalent fraction. 6/7 = 17.2/20

You can do this with any number. If your assignment is only 16 questions but you want it to be worth 40, you do the same process. Take the number correct out of 16 to find the percentage. Take the percentage X 40 to get the correct number of points.
