About all you can do is ask if the teacher would grade it. Heck he could even grade it himself after school with her sitting right there working on something else she needed to do...all she would have to do is open the book to the answer key. If they had a standing date for ten minutes after school on Thursdays...he could whip through the beginning chapters and only stop and do what is necessary.
In second grade my son's teacher gave him the comprehensive pretest for math which takes two class periods to administer. He scored as having mastered 85% of the second grade math content. So she then put him at the back table and would give him chapter test after chapter test interspersed with time to play math games on the computer....until he got to chapters where he had gaps and couldn't get 100s ( he didn't have to get a hundred it was just he either was getting a hundred or was lacking that skill). At a chapter with gaps, she went over it and he worked through it and then back to taking chapter tests....he completed all of 2nd grade math this way in the first nine weeks.
