It varies depending on activities, but as a snapshot, this is what our Thursday looked like last week:
Morning: we did sit down "book work". We did some french flashcards (at the moment it's the weather) and listened to a piece of classical music from the book "A Year of Wonder". I read them a chapter of our current readaloud and the boys then did some reading comprehension questions based on that, and then some handwriting, spelling and grammar practice. They then each did their own free choice literacy based activity - for DS1 this was working on the story he's currently writing and for DS2 this was writing an acrostic poem. They went out for a kickabout in the garden while I prepped their maths activity - we all do a logic puzzle together using maths manipulatives, they each did a couple of pages of their respective maths workbooks, we played a maths game and we did some quick times table revison. This took us up to about 11am, when they had another run around the garden. Then we went onto Science as our slightly deeper dive (some days we do History, some days Geography etc) - we are doing biological classification. We went over the mnemonic the boys had already learned to remind them of the biological classification order (domain, kingdom, phylum, class, order, family, genus, species - mnemonic device Keep Ponds Clear Or Frogs Get Sick). I then asked them to look in our books to choose any animal, pick its 3 main features, work out based on that what other animal it might closely be related to and then draw a hybrid combination of the two of them. That took us through to lunchtime - they played outside while I got lunch ready and then whilst they were eating lunch they read whichever books they're currently reading independently (and I ate my lunch at my desk catching up on some work). DH works from home so he came downstairs, had lunch with them and then they played a game of cards and had a quick game in the garden before he had to go back to work.
Afternoon/evening: Thursday is multi sports home ed so I took them there - the session is 90 minutes and afterwards all the kids went to the park together and played there for another couple of hours (or thereabouts). We got home around 4.30, they watched TV while I made dinner. DS1 has a music group in the evening so we eat early on a Thursday and I take him to that whilst DH takes DS2 swimming with a couple of (schooled) friends. They both had supper when they got back, we played a board game together, they went to bed. I did a couple of hours work that evening, watched a bit of TV with DH, went to bed around 11.30.
Hope that gives an idea! Just one example, we do different stuff each day but it's a fairly similar formula.
Yes, we do have a garden. We did used to live in a flat but that was pre home ed.
They didn't have much screen time on Thursday but I do usually let them play a bit of minecraft first thing in the morning, and quite often for science or history they will watch a video. Some days they have more screen time than others of course.
