It seems simple but I think a nice way to have kids get into solving equations is to do a set of problems like this.

I always used to start my lesson on squaring binomials with this but extended it to the form (n + a)2 = n2 + 2na + a2 and would start by asking kids for whole numbers close to 50 and I would square them in my head before looking at the algebra that showed why it worked.

I appreciate that @JennaLaib continues to add to her collection of slow reveal graphs and I also like the reminder that we shouldn't steer away from controversial topics. Check out some of the new graphs including the one on the correlation between gun deaths and gun laws.

If you are playing with prime numbers then this is neat. 561 is a not a prime number but by over 100 different prime tests it comes up as prime.

Some of these properties, I didn't know existed for right triangles. That being said, I created a Desmos Geometry sketch that lets you (or your students) test these properties out.

I think this would be a good thing to look at for students of all ages. For the younger ages, it's practice of multiplication and for older grades it practice of number theory.

I love this latest episode of People I mostly admire. Such a great story of Ken Ono who dropped out of high school but went on to become a math professor who eventually helped the US swim team win Olympic medals and consulted on the film The Man Who Knew Infinity. See this and all the podcasts I've found related to math at my math podcast page.

I think that no matter what level you teach at (or were a student at) this happens. Whether it is the idea of feeling dumb (as a student) or assuming the students know more than they do (as a teacher). As students we have probably all felt this (though maybe at different times in our time as students.
