I dk how they do it but a montessori school by me does teach to each kid individually. It somehow works. Kids are not pinned against each other. The parents know each kid is doing their own thing. They all have diff books etc. When a child finishes a book they move on to the next level book. There was no following the group. I just wish the school had higher grades. They have individual instruction and it may not be all day but even 10 minutes of individual attention is better than hours of useless instruction. Most of the kids flourished. It is amazing the difference in a traditional school setting.
