Hi, my daughter is 6 but has a developmental delay of pprox 2 years. She is also being assessed for ASD.
We do all our formal work in the mornings, as her concentration gets worse as the day goes on. She starts with her Brain Gym programme of excercises, breakfast, then speech therapy games + work sheets, writing for perpose, eg a letter to someone in the family, inc phonics and some words she'll have a go at spelling on her own, with magnetic letters. Then a snack, then some drawing/playing, then I'll read to her nd ask questions about the story. This takes us up to about 11am. We usually start it at 8:30am, as she's usually raring to go by this time.
That's more or less it for the formal so far. The rest of the day is spent either playing, going out, nature walks, riding bike, cooking, baking, meeting her friends, I'll let her watch a DVD with me some days, if she's done well with her HE. We also play a lot of games together, mostly to work on listening skills and concentration etc.
She has 2 days off a week, but still has to do her excercises on those days. I've found tht even her "days off" are filled with learning, eg at the local farms, national trust places, the zoo, etc.
The only thing I don't think she's covering is maths. WE talk about measurements when it crops up in cooking etc, she'll measure things and I'll ask wether it's more or less etc. We'll count out things we need as well, but I'm thinking we should do some form of maths as part of her morning? Perhaps a simple maths game? I'd be greatful if you can recommend any fun maths games or activities. She really doesn't like maths, but is always willing to play a game. 
Do you think this is o.k for now? When she's older, I'll be getting her a tutor, but I don't think it's really worth it at the moment. She's doing as much as she can deal with I think. I always know when our morning sessions should come to an end, as she starts being silly, not listening etc. I'll always end on a positive and give her a sticker and marble for her pot.
If anyone has any tips or ideas for fun activities that'll help her learning, especially in maths I'd be really greatful.
