skip the fill-in-the-blank and encourage more writing!
Often times, it's hard to get away from worksheets. Sometimes schools or districts mandate that you use a certain number/all of given curriculum series to prove "fidelity to the core" (glad I haven't worked at places like that!) or you're not sure how else students could practice the specific concept.
I like to take worksheets and cut parts of it to encourage more writing.......as seen in the pictures below. I put a worksheet on the document camera/overhead to give students sentence frames (or at their table if they need it).
I try to avoid fill in the blank (different from cloze activities which I know are powerful and helpful), as I saw that this was almost never done in England or Australia and students there wrote a LOT more (yes, this is a bit of a generalization).
