Common Core Sheets 

And you can save even more time by grading multiple papers at once! Grading an entire classrooms papers takes only minutes!
The numbers on the left (in this example 110 and 1115) tell the number of problems missed while the numbers in the boxes give the score. So for example, if a student missed 7 problems, they would score a 53. If they missed 12 problems, they would score a 20. Give it a try and within minutes you'll wonder how you ever lived without it!
