Tears again this morning. 
He failed to make a note of when his food tech ingredients were due in (well he did make a note, just noted they were needed on a day he doesn't have food tech
). Got him to text a friend who is in that class and he didn't know either. Raised it this morning, as he now has to find out and insists there are no other pupils in any of his other lessons that also attend his food tech group.
Friends again now and it has been pointed out, better a cross Mum that loves him than a stroppy teacher with detention as an option. We had a hug and a chat and I've given him his favourite crisps for break time, even though he's only usually allowed crisps on a Friday. He ended up going off with a smile, so I think we're back on track.
Wrong due dates on homework we can deal with, just do it the night you're given it so it's ready whenever it's needed. Food tech ingredients at short notice will be an issue for me though, as I don't drive and we live in a village, so I need to plan when to buy them. We have all the recipes for the year, which will help, but the first dish is all fresh stuff, so I can't buy it in advance, as with a two week timetable, if he gets it wrong it won't keep.
Dh and I were just discussing last night how the primary school doesn't do enough to teach them good organisational habits and other skills they need for secondary. Y6 is basically just fun-stuff after the SATs have finished, but they need to be learning good diary/planner habits etc, so instead end up going into Secondary in September having hardly done any work since May and total unprepared. Life skills like hygiene, time-keeping, shoe-laces, etc we can do at home, but as my dcs don't have lots of clubs to attend etc there's only so much we can do to teach things like diary skills.
Planning to move his bedroom around this weekend to incorporate a new, bigger desk with slots he can use to organise his school stuff. Also have a wall planner we can put up for him to use, so hopefully he'll soon get into the swing of it.
So different than with ds1, as we still have to do all his organisation and his homework is recorded by an LSA, so this is all new to us, despite having an older dc already at secondary.
