We do every subject every day. I really have to get a hold of the PS (they have not yet returned my phone call it's going on two weeks) because of the Common Core, the PS does not do Social Studies and Science as a main subject so really why should we have to. So I have to find out what is actually required. My girls love Science so we will probably still do it every day but they find History very boring well certain aspects are very boring to them so I have to find out what we will be doing for next year (even though I bought the books already).
We don't have a set schedule, but we always do math and some kind of language arts. We will often do Social Studies on day, and Science the other day. Sometimes we will do no science, only social studies, for a month and the reverse.
