 How to Grade Questions about grading your students work? Example: Mathematics Your son Gary just completed his first week schedule in math. This first week he completed 3 units or sections. One unit/section contained 24 problems, the 2nd unit had 16 problems and the last unit had 11 problems. The last unit also had a unit review with 28 problems. What do I do? Let's say that on the first section, (the one with 24 problems) Gary missed 5. Simply divide 100 (the total points possible) by the number of problems: 100 ÷ 24 = 4.16 Each wrong answer is worth 4.16 points. Multiply the total wrong answers by 4.16: 5 x 4.16 = 20.83 Subtract this total (20.83) from 100: 100 - 20.83 = 79.17% or 79% 79.17 rounded off to the nearest whole number gives Gary a 79%. Simply write that at the top of the page. Continue the same pattern with the next two units. In the 2nd unit Gary had only (1) one answer wrong! That unit contained 16 problems. 100 ÷ 16 = 6.25 6.25 x 1 = 6.25 100 - 6.25 = 93.75% or 94% Yippeeeee! Gary scored a 94% on that unit. The last unit had 11 problems and 2 wrong answers. 100 ÷ 11 = 9.09 9.09 x 2 = 18.18 100 - 18 = 82 or 82% In the 28 question unit review(we used to call them TESTS!) Gary incorrectly answered 4 of the 28. 100 ÷ 28 = 3.57 3.57 x 4 = 14.28 100 - 14.28 = 85.72% or 86% Add the 4 totals together and average them for the week. 79 + 94 + 82 + 86 = 341; 341 ÷ 4 = 85.25% Gary’s average and final score for the week = 85% Repeat this for the final grade and you have the grade to submit on your Pinnacle “Grade Report”.
