Wow–how has it been a whole month since I last posted math warm-ups? Oh, yeah, because MARCH was crazy–including a SNOW DAY and SPRING BREAK right next to each other. And not that April is any less busy, but at least this week could be considered somewhat normal. Oh, not it wasn’t–I had a sub on Tuesday. But hey, what’s normal anyway, right? Regardless, here are some recent math warm-ups I haven’t shared yet.
First of all, a couple from last week:
This one was to help discuss fraction place value, and also to help us talk about writing clear and concise answers to questions like these (in preparation for MAP testing in just over a week).
Can you tell I ran out of paper and didn’t have a chance to get more for a couple of days? Sorry. 🙂 This one is another place value one, hoping that students would see the relationship between money and fractions, and how they can just “move” the decimal (by multiplying by 10), rather than having to use the algorithm to solve the problem.
This week’s warm-ups:
Wednesday
We needed to reminded (again) about equivalent fractions, as well as their tie to decimals.
This one came right off of our Edison benchmark practice from this month. We’re using the problems on that assessment to help us analyze the “why” of the ones we get wrong. This can help us not make those same mistakes again the next time we encounter them.
This is another Edison problem, but I changed the numbers. Many students are still not remembering to make the denominators the same before they add. This one also elicited great conversations around simplifying answers–both how and why here as well.
I’m hoping I’m back in the routine of posting warm-ups. Sorry if you’ve missed them! 🙂
