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.

Targeting aspects of rigor in math instruction

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.

Targeting aspects of rigor in math instruction

by Sarah Tierney

Math teachers, spurred by new standards, are striving to increase the rigor of their instruction. But…what exactly is rigor?

According to the Common Core, achieving rigor requires us to teach math in a way that balances students’ conceptual understanding, their procedural skill and fluency, and their ability to apply what they know and are able to do to real-world, problem-solving situations.

But this is easier said than done, especially when most of us learned math through a less balanced approach that favored rules and tricks over deep understanding. In light of the Common Core, many teachers have found it necessary to expand their instructional practices to support student learning across all three aspects of rigor.

Conceptual
Understanding
Procedural Skill/Fluency Application
Understand
Reason
Explain
Interpret
Fluency
Count
Read/Write
Evaluate
Word problems
Real-world scenarios
Multi-step problems

The language of the standards helps us identify which aspect of rigor is being targeted, as shown in this chart. Once you understand that, you can identify the most effective instructional practices to employ. Different standards demand different ways of learning math—conceptual, procedural, or application—and that means our teaching needs to adapt to meet those demands, too.

Different standards demand different ways of learning math—conceptually, procedurally, or application-based—and that means our teaching needs to adapt to meet those demands, too.

Sound tricky? We created this guide to help spark ideas for how to structure your instructional approach based on the aspect of rigor.  The guide might also come in handy if you discover that material didn’t quite “click” for students the first time around—it might help you re-think your approach or choose a different strategy to engage students with the same math topics in a future lesson.


We’ve spent ten years learning from thousands of leaders and teachers across the country about the things that make a big difference for schools. Now, we want to give you the opportunity to do the same. We’ve organized these Lessons From the Field in a new section of our website by our main areas of focus—everything from harnessing the power of formative assessments to fostering a culture of adult learning.
