I began as a high school math teacher, moved to middle school, and then to elementary school to learn about how young children make sense of math. I love thinking about how to uncover math for kids. I blog about lessons I teach at www.marilynburnsmath.com.

A screen shot from a new sitcom, The Paper. I wrote Math for Smarty Pants in 1982! How did it get here?
I never heard before about "highly composite" or "highly abundant" numbers. I learned about them from Cambridge Mathematics. createsend.com/t/y-2916A5BF...

I picked bush beans this morning from our garden. No, I didn't count, but I confess that I was tempted. Will they serve 4 at dinner tonight?
Why am I confused by this sign?
I was teaching 8th grade math when Tom Lehrer released the album with New Math. I played the song at back-to-school night. (I was required to teach new math with the SMSG materials.)Tom Lehrer was a wonder.
And Cricket isn't natural to me. I'm still puzzling.
I loved this!
I really hope people enjoy reading this as much as I enjoyed writing it. It's a retellilng of the battle between Tartaglia and Cardano over the cubic.

Who Gets Credit For Great Ideas?

I read The Way It Spozed to Be by James Herndon in the 1960s as a beginning teacher and it spoke to me then. I haven't reread it. Then The Having of Wonderful Ideas by Eleanor Duckworth, which I've gifted to new teachers and which I've revisited over the years.
Some books don't just shape us as people—they transform how we show up in our classrooms.

Teachers, what book shaped you?

Oooh, I liked this string about squares and rectangles. Some new ideas for me.
If you had to define a quantity to represent how far away from or how close to being square a rectangle was, what would you choose?
This reminds me of what I learned from my undergraduate advisor Bob Davis. He said that a student's wrong answer is the right answer to a different question. My job is to uncover that other question and move from there.
It's on my mind because a colleage at another uni was moaning the other day about how maths courses have been "dumbed down" over the years. Even if you think this is true, your STUDENTS aren't dumb. The maths you think is dumber is still advanced to them.

I really appreciated the openness and civility of this exploration of differing perspectives of the ‘science’ of mathematics. A good listen.
Thanks. Yup, a typo for pronic. I also checked Wikipedia. Sometimes automatic spell check is really annoying.
Zero is a phonic number? I'd never heard of phonics numbers. Cool.
Zero
Zero is an even number as it is divisible by 2 with no remainder.

How did I get this far without ever learning about semiregular tilings? Cool. polytope.miraheze.org/wiki/List_of...
Not for everyone, I know, but I found this to be a really good read.
