I think your thinking sounds great :). It’s true that teaching a different strategy between each round would be a lot for students to take in and really digest. I do think it is better to work with the same strategy, perhaps i once through reading and once through writing–or through fiction and then non-fiction text.
Another thing to think about is to be aware of how your students respond to the strategy you’re teaching–do they exhibit some misunderstanding during your conferring and read to self/work on writing? You may pick up on a misunderstanding that needs to be addressed in a followup mini-lesson. Of course, all strategies will be revisited throughout the year, so mastery may not be reached during the first time(s) you teach them.
I’m sure other teachers have hints and suggestions that will give us all new ideas!!
