Non-competitive sports days have enormous benefits for the younger children (prep school age). Whilst my school has traditional events like the triple jump, shot put (cricket balls) and javelin, we have things like wheelbarrow races and best self-portrait whilst running 50m.
Rather than tell a child who's a little behind physically that they're slow and weak, we nurture a love of competition; imagined or not.
We had an alumni compete in Brazil. Teachers still remember her lack of ability as a prep-school child. We played out part fostering what was there and she won a medal. We also have houses. Often the points are arbitrary. Guess what, defying the laws of probability, house points are nearly always in rotation between the houses (day and boarding).
Correct grammar is important and one of the reasons that all children study an MFL from Year 1. "Full, clear sentences" need correct grammar, full stops and capital letters.
I'm not too sure what you mean by "grammatical exercises? He's asked to change sentences from future perfect continuous to pluperfect?
This isn't meant to be a sly dig but does your 9 year old have AEN? He shouldn't be missing words or forgetting full stops, capital letters etc at 9. If he does then using him as an example is unfair. If he doesn't then something is going drastically wrong with his education.
