DH saw a conversation on his work Yammer board today, about ideas to keep kids positively occupied during the summer holidays. There was a suggestion for a "summer challenge", where children could get points by doing constructive things - reading a chapter of a book, tidying their bedroom, doing something active, healthy eating etc.
Apart from a week's holiday and the odd day trip, DH and I will be WFH for the rest of the summer holidays, so the children will be relatively neglected (they'd normally go to a holiday playscheme, which they love, and where they get to do all kinds of exciting sports and crafts, but it's not running this summer 
). I think a holiday challenge scheme would be good this year - not because we're trying to micromanage the DCs' time, but more to persuade them to do something other than watch TV/play on tablets while we're working.
Has anyone else tried this? Any ideas for things we can include as challenges? We thought we'd split the list into mind, body and spirit (for want of better descriptions) - so things that encourage them to stay active and healthy, things that will keep their brains active, and things that will be relaxing or enriching. We've also thrown a few "pulling your weight" items as well (I know someone will come along and point out that they should be doing these things anyway, but they're not, so I'm just being pragmatic 
). DCs are 7 and 9, and one of them has some disabilities but not hugely limiting ones.
So far we've got things like music practice, reading, Lego or drawing challenges, making their own breakfast and clearing up afterwards, making bed and putting clothes in the laundry basket, coming for a walk willingly or going for a bike ride, doing some Duolingo practice (they both started doing this at half term). But I'd love some other ideas.
Also: any ideas about what they could convert their points into? (I was thinking spending money at the local toy shop...)
