I got a weird note from a parent today. It said, student will be doing -aaa- instead of -bbb- (the assigned task) for their homework assignment each week. No extra explanation was given. Honestly, activity -aaa- is a fine activity that practices the same skill as -bbb-. But I find it strange that the parent provided no reason, and didn't ask, instead just assuming this was their decision to make. The assignment is just basic practice, so there's no chance it's a moral disagreement or anything like that, and the alternative assignment they chose is about the same level of difficulty, so it's not that they need their child more or less challenged. How would you handle that?
