How many students are in your child's class? My oldest has, what seems to me, a large class. I always feel overwhelmed when I go to his class for parties or projects. I can't imagine how his teacher feels!
ETA: just the classroom, not the total class size. My oldest is in 4th grade. They have three 4th grade classes, but his room has the most students.
My oldest has 25.
Middle has 22.
Youngest has 18.
