Next, I need a pictograph! Here is the data: grades k 120 students, 1st grade 80 students, 2nd grade 125 students, 3rd grade 90 students, 4th grade 130 students, 5th grade 160 students, 6th grade 140 students, 7th grade 95 students, 8th grade 100 students. (k means kindergarten just in case you didn't know)
