We did have some school on Saturday. But I don't know if you'd consider it "school" so much as some "family learning time." For us those two are pretty synonymous.
When I came out of hibernation the girls were already playing with "supermind" and "shape by shape." CC#1 worked for a while on her dragon picture for Chinese History. She also got some practice with math facts.
I worked with CC#2 on some preschool concept pages, handwriting practice, letter review, numbers and counting, vowel short sounds, and a couple of words for reading. We reviewed days of week and so forth, things we review every day.
I don't remember what else we did, if anything. I did read to them a couple of chapters of our read aloud selection also. CC#3 had a short story time as well.
