Begin by communicating with them about why you give “homework” and how these reasons are embodied in the name check-your-understanding questions. Explain that the questions that may or may not be coming home are to be treated as a safe place for their child to make mistakes and that the purpose is for them to learn from these mistakes. If they insist on having more questions for practice, you can tell them that ample practice questions can be found on the internet, but that they will not be part of your teaching practice.
