The last month has seen a plethora of discussions about the necessity for teaching math beyond what most jobs consider necessary. Much of it started from Andrew Hacker’s now infamous article on whether math is necessary, to which a bunch of us replied with equal fervor (Dan Willingham’s and Sherman Dorn’s pieces are great rejoinders). What we all seem to agree on is that, indeed, the way we teach math matters. Lots. Having a positive environment for kids where they feel like they can actually *do math* without feeling like they’re complete failures matters a lot.

Often, that starts with us as teachers.

Developing an environment where students can experiment and gain entry into the language of math starts with having a person who can facilitate what Stephen Krashen termed a low affective filter environment. While his study was applied to English Language Learners, his hypotheses should apply to all subject areas, math highest among them.

In my classroom, I have five principles for assuring that all students can enter into the math, and also for creating the conditions for math success.

## 1) Allow More Mistakes

I would suggest this to just about every teacher, but specifically math teachers, especially those of us who use the word “wrong” a lot. We should strike a balance between using direct instruction and exploration, leaning more on the exploration piece. Once we allow more mistakes, we let students into the process that our earliest mathematicians used in developing the axioms we believe today. Also, by admitting that we all make mistakes, it sends a clear signal to kids that they can be mathematicians, too. Surely, I’m not suggesting that we let the mistakes be. Yet, when I make a mistake on the board (intentionally or otherwise), I hope my students catch onto that, thus putting them in the position of expert. Speaking of which . . .
