Math CoTeacher

Built for teachers, by a teacher, alongside teachers in their classroom.

The initial focus is on elementary school mathematics and building a rock solid foundation.

Who am I?

I am Mark Pettyjohn.

I've taught 4th grade, 6th grade, pre-k, and kindergarten.

The work my students did in our 4th grade classroom garnered me a math teacher of the year award, horribly unfair for my students, I know. Don't feel too bad though as they earned themselves representation in chatper 11 of Tracy Zager's book Becoming the Math Teacher You Wish You Had showing their chops about how 4th grade mathematicans prove their conjectures.

I want to see a mathematically literate world. Math CoTeacher is a way I see to help students and their teachers get us there.

Want to work with me?
