ANet is a nonprofit dedicated to the premise that every child in America deserves an excellent education and the opportunities it provides. We pursue our vision of educational equality in America by helping schools boost student learning with great teaching that is grounded in standards, informed by data, and built on the successful practices of educators around the country.

Rigor in mathematics

ANet blog

As a mission-driven nonprofit organization, our primary concern is helping ensure equitable opportunity for all students.

Working alongside schools, we’ve learned that great teaching is grounded in standards, data, and insights shared among educators. We believe a blog can help us make a difference by spreading the ideas and effective practices of educators we work with.

We’re proud of the expertise our team has built over our ten years, and we'll be featuring contributions from ANetters across the org on topics in which they’ve immersed themselves.

Help us spread opportunity for all students: please share posts that you find valuable with your colleagues. And please add your thoughts in the comments: we would love this blog to facilitate knowledge-sharing in all directions.

Rigor in mathematics

Becky Frutos

What is rigor in mathematics?

Rigor doesn’t just mean “harder” or “more difficult.” Rigor in math teaching means focusing with equal intensity on students’ conceptual understanding, procedural fluency, and ability to apply what they know to real-world, problem-solving situations. 

Why does rigor matter?

Aspects of rigor
  1. Conceptual understanding
  2. Procedural fluency
  3. Application

Instruction that targets  all three of these aspects of rigor develops well-rounded mathematicians. It gives students a robust “toolkit” they can use to solve the wide range of problems and tasks that will come their way.  

Is your instruction rigorous enough?

These tools and resources will help ensure your math lessons meet the mark in terms of mathematical rigor.
