#SmudgeMath is a great way to make a question a bit friendlier and encourage work on more difficult questions. Just about any question can turn into a #SmudgedMath question but here is a bunch premade.

Starting to think of a spring/summer project - should I revisit and compile more #smudgedmath tasks? www.normabgordon.com/smudgedmath-... #iteachmath #MTBoS #imentormath

To me this is more evidence that mathematics is something that is discovered (by any being) and not invented (by humans)

A crow’s math skills include geometry Crows are able to look at a handful of four-sided shapes and correctly distinguish those that exhibit geometric regularity from those that don't, according to a provocative new study. www.npr.org/2025/04/12/n... #philsky #philosophy #intelligence #crows #math

I like these types of questions because, I think, at first glance they seem difficult but upon further scrutiny, they are quite do able.

Here's the question for April 24th from the AMS Daily Epsilon of Math Calendar. For those unfamiliar with the calendar, the answer is always the day of the month. Looking for imaginative solutions is the aim. #mathstodon #math #maths #mathematics #MathsToday

It was always one of my favourite things to find something out in the wild that would connect to the curriculum I'm teaching and make students say "hmm". Make sure you check out the comments for the answer

I think it's important to find things that are thing that kids might be thinking of and making money on the Internet is definitely one of them.

I like this kind of question because it seems harder than it is but with a little care, it should be do able. Can you guess why this was published on the 18th?

I really like this problem because you can take a brute force method with skills as complex as those found in gr7 & 8 or take it all the way to Calculus. I threw my hat with a dynamic geometry solution here.

Even though we can't see the presentations, I think the summaries offer some good ideas. This one is my favourite: " Don't focus on getting info INTO students' brains, more on getting info OUT!". Check out the original post to see all of the 7 for 7 presentations at the TI conference.

Even though some of these are most certainly university level equations, there are definitely equations here that fit into the high school math (and physics) curriculum.

I think this could be used when talking about number systems (in terms of triangle numbers) or to conceptualize the patterns that exist in (this particular) sequence.

This seems like the kind of question that has brute force solutions and more elegant solutions (and code based solutions). To me that makes it perfect for all grade levels.

Happy Monday! This problem is inspired by the 1971 Canadian Math Olympiad Q7 Which are there more of, 2-digit numbers that are divisible by their 10s digit, or 2-digit numbers that are divisible by their unit digit? #math #maths #ProblemSolving #iteachmath #mathsky
