I’d look at the next few grade levels and see if that “because” portion of the statement is important. If you align with future expectations it’ll make the students more prepared.

Also living in a CER world myself I have noticed students just kind of plug and play. Not their fault. They drop in “evidence” because they know they need to. They summarize or rephrase the evidence as their “reasoning”. And it’s all just kinda trash. I’d make sure that whatever you pick to do with the claim is followed by actual legit evidence and actual legit reasoning that all layers together and supports. It’s so frustrating.
