How many examples do you need to prove something?
November 27, 2018, 2018 | Teresa Lara-Meloy & Jennifer Knudsen
We have spent more than 10 years studying math argumentation in middle school, in part because early teenagers are in an interesting stage in their development of argumentation skills.
Using visual representations to support all students: Snippets and resources from NCTM presentation
May 2, 2018 | By Hee-Joon Kim
Next week, we present at NCSM on how the 4-part model for argumentation is foundational knowledge on which teachers can build up teaching moves.

Next week, we present at NCTM on using visual representations in the math practices—mostly argumentation, considering it’s us.
Conjecturing for All!
March 7, 2018 | By Jennifer Knudsen
I recently re-tweeted Christina Cho’s (@ccho01) tweet on her second graders’ conjecture wall. So inspiring! If second graders can conjecture, so can middle schoolers, don't you think? We’ve found it to be true.
How do you choose tools?
January 21, 2018 | By Hee-Joon Kim
How do you decide which tools to allow for students to use to “do” mathematics? When we say doing mathematics, we mean students engaging in exploring mathematical ideas and concepts.
Mathematical Argumentation as a 21st Century Skill
December 12, 2017 | By Harriette Stevens
We were recently lucky enough to present at the annual conference of the National Alliance of Black Educators. Our session was entitled, Advancing Students’ Engagement, Communication and Positive Identities as Mathematics Learners.
Are your students afraid of expressing their thinking because they don’t want to be wrong?
November 6, 2017 | By Jennifer Knudsen
Mathematical argumentation is improvisational! As you and your students create mathematical truth together, you all have to respond in the moment to what others are saying and doing....
7 Steps for Engaging Students Through Mathematical Argumentation
October 23, 2017 | By Jennifer Knudsen
Mathematicians have been figuring out the mathematical truth for millennia. Can this possibly be relevant for today’s students? Yes!
Students Need to Take Mathematical Authority!
October 22, 2017 | By Jennifer Knudsen
Mathematical argumentation is the perfect opportunity for your students to develop their own mathematical authority—their sense of self as creators of mathematics, in charge of deciding the truth for themselves. We elaborate in an excerpt from our new book.
