I have always liked the idea of warmup questions. Something for kids to do as soon as they step in the door. Nothing too crazy, maybe with different levels of difficulty. And even though these examples are for Calculus, the idea is universal.

A few warm-up questions from this week in my high school Calculus class. I start each day with a question. Sometimes for review/retrieval, sometimes to launch the day's discussion and sometimes for practice/consolidation. #ITeachMath #MathsToday

Asking for questions is a good way to get more students involved. Especially for students that struggle and for students that excel, you can give them a specific topic.

A change in perspective can make all the difference! T Kathy Minas (themathcollective on IG) mixes it up by giving the answer first – and asking learners for the question: www.instagram.com/p/DO1o9bSEmr9/ #MTBoS

#mathstoday started with one of my favorite early probability activities. Students write events on stickies for almost never to almost always and another group tries to sort them. Lots of discussion about wording and googling for more info.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...
