Depends on the subject. We have been done with English and Math for over a month now. History, not so much. I don't mind not finishing a book as long as he has been learning all year. We can always continue it next year if we want to.
This year we will for sure have finished every chapter, except for Riley with math. We started his math year during Christmas 2 christmas-es ago, so he won't technically be done with his book til Christmas. We plan on doing math through the summer with him though so we can start next year with the new book. Last year though, Jamie didn't finish her math book last year, she only had a few chapters left, but we stopped the year, and finished the book at the beginning of this year. I guess it just depends on how the shcool year is going and how long we can drag it out before it gets too busy.
We finish books all the time but at different times during the year. Depends on the subject. We use a living book approach to history and science. We also pick out what we use out of textbooks. We never simply just use a textbook. The only exception is probably math. We homeschool year round so we finish the school year sometime in August. Our math will be done by then and we started only a coupld months ago. We switched very recently. We stared something new for english as well. It is multi book program. We will not have write shop finished but I wasn't planning on using for two years. I just realized how all over the place I am with this answer.
Usually, no but now that they are in a high school program, yes. But I disagree that those in PS finish all of the text. During the short time mine were in PS, there was a lot of jumping around in the texts and certain parts weren't used at all.
no, in fact, we've abandoned the social studies textbook I bought, and we never eveen started the grammar workbook I got. I may try to do the grammar workbook over the summer. We will do math all summer.
