Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Use one unused source after a specific reteach. Give its first source alone, preserve that response, then reveal its separate new condition. Allow about 15–20 minutes for the first response and up to 10 minutes after the later condition. Record timing and support; agreed extra or split time is welcome. Prior source/key access ends a fresh claim. These forms are not equated.
