Year 1
Reading every day, minimum one Mr Men book atm as he got the set for Christmas so he's ploughing through that and we're seeing rapid improvement in fluency doing this.
Phonics games every day for as long as he wants, usually about an hour.
Writing every day, either he writes stuff on his easel (blackboard one side, white board on the other), or a shopping list, recipes, simple sentences. I have all but given up on handwriting. That will come with time in school, he is only year one and has years to get that down. It's readable but not always formed correctly (which I think is pretty standard for y1 anyway?)
Other subjects get done in a slightly more organic way - he'll see something in a cartoon (lots of magic school bus and messy goes to okido being watched) and then we'll read /watch a bit about it and he might do a bit of work related to that. Eg, did a bit about recycling last week, he built a Lego city with a recycling centre and dump truck.
Maths is a sheet a day, plus a bit of playing shops /measuring and weighing for baking etc.
We're doing a bit most days including weekends but not much overtly formal stuff. Will continue over the holidays.
School have sent home work packs and we've dipped in and out of them. Been useful for writing prompts and maths but cross curricular had been roundly ignored as I'm not going to make him research kings and Queens of England when he categorically does not care about that topic.
It's becoming more of a struggle as time goes on though and he is getting a bit cheeky lately and refusing to engage as much as he did at the start, but I'm not battling him over it (apart from the cheek) because it's really not worth the stress.
Some days he's keen to get a load of school work done, some days he's not. So I'm just playing it by ear now.
