A tip I would suggest is to not recreate assignments and quizzes on formative. You can upload a current electronic document from Google docs, Word, PDF, etc. into a formative. All you would need to do is provide the questions on the already created document on formative. I have provided an example of what it will look like.
That seems pretty cool, can you upload things like newsela? I’m pretty “green” at formative but it seems like a very versatile tool.
