Reminds me of what I was dealing with last year. The first month of school went by and I had no idea DD was supposed to be doing homework for math, and I had no idea even what chapter of the book she was working on. The textbooks stayed at school, but I asked if I could bring one home after a while. At home she was supposed to watch online videos, that were each 30 seconds to around 2 minutes long and then do 4-5 question quizzes based on the videos. Half the time the quizzes had nothing to do with the videos. With some questions, there needed to be a written response, which the teacher was supposed to check online but sometimes weeks would go by with no checking. It was quite frankly, ridiculous. All of the kids in the class were basically working at their own pace which added to the chaos. I never had any idea when the tests were going to be.

From what I hear, we are doing the Envision curriculum this year (different school) and I know there must be something online, but so far the kids (who are now in the same level) are bringing home worksheets as "review". I am bracing myself for confusion. I am going to ask for a textbook.

I have no real advice, it sounds like you are trying to reason with the teacher and she is resistant to communicating. I suppose you could request a conference.
