When DS9 was in K he was in a montessori similar situation. This was also 8 to 1 teacher. The communication was open between the teacher and student. He was asked and allowed to say if work was too easy or too hard. He would then get harder work sometimes. That felt good to be proud of his work. It's so hard to deal with our current school where they don't know if they are teaching what he already knows. This is 28 to 1 teacher and assistant.
