Were a bit different because most of my kids schooling are through online classes.. However for my younger she does 30 minutes for each of her online classes which covers math language arts Science and an elective.
We cover history , geography , handwriting , writing, religion and hands on science separate..
History we do 1 chapters lesson over 2 days
Read day one review new words places people
Re read and answer questionspeople
15-30 minutes typically
2 mapskills lessons weekly 5-10 minutes
1-2 pages handwriting hwwt works to a check box 10 minutes
Writing with ease 2 days at a time including reading discussion and writing time maybe 15 minutes
Religion daily lesson short 5-10 minutes
Hands on science done as either relate to something she is learning or oppurnity presents it self time greatly varies.
As for math and history.. For math i find 30 enough for her age and ability to focus well. We used to do 40-45 but I noticed she'd often get frustrated even if concepts weren't giving her trouble and ready to give up when they did.. She actually decided it was worth needing to do a 5th days lesson in math and find arts rather than pushing too much for 4days..
History honestly at her level and age i keep history little more that simple story te!ling at basic recalling of information. Virtually everything will cycle again in more detail and at that time more will be expected for now what we do is plenty.
