In math, graded means that you get assigned a score or a level based on how well you did on a test, assignment, or project. For example, if you take a math test and get 90% of the questions right, you might receive an "A" which is a high grade. If you only get 60% of the questions right, you might receive a "D" which is a lower grade. The grades usually go from A to F and can show how well you understand a certain topic in math. So remember, when you get a grade in math, it shows how well you did on your work!
