For Elementary and Secondary

Illuminations includes online manipulatives, games, and interactive tools.

  • Initial exploration experiences;
  • Manipulatives to make sense of concepts;
  • Independent practice towards fluency; and
  • Re-engagement of previously-taught concepts.

Each interactive has the activity, instructions, suggested explorations, and related resources.

Illustrative Mathematics (K-12)

Illustrative Mathematics is a discerning community of educators dedicated to the coherent learning of mathematics. We collaborate at, sharing carefully vetted resources for teachers and teacher leaders to give our children an understanding of mathematics and skill in using it. We provide expert guidance to states and districts working to improve mathematics education.

Which One Doesn't Belong is a fun website full of thought-provoking puzzles. Many of them appear as Math Talks in our curriculum. They help to engage even your most reluctant students because of their open-ended nature. They also support a positive math community by building confidence and appreciation for the unique ways in which we all see things.

Dr. Jo Boaler's website,, has many resources for teacher and student learning. Here are some of our favorites:

A Three-Act Task is a whole-group mathematics task consisting of three distinct parts: an engaging and perplexing Act One, an information and solution seeking Act Two, and a solution discussion and solution revealing Act Three.

Some resources for 3-Act Tasks are from these blogs:

NRICH (K-12)

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

NRICH is a team of qualified teachers who are also practitioners in RICH mathematical thinking. This unique blend means that NRICH is ideally placed to offer advice and support to both learners and teachers of mathematics.

For Elementary

New research shows that when parents and caregivers do a little math with their child every day, math learning is supported, even if the adults are math-phobic. Bedtime Math is a resource that provides a picture, a little bit to read, and an interesting math challenge at four levels (“Wee Ones” to “Sky’s the Limit”) every day. It can be accessed through their app or on their website. Adults initiate a conversation each evening at the dinner table (or at the breakfast table, or whatever time works for them) about the math, which builds children’s comfort with engaging in mental math, their number sense, and even their achievement in math class. The research showing the positive effects of these conversations were covered by many news outlets.

Developed by teachers, Zearn Math is a groundbreaking K-5 curriculum and classroom model that supports differentiation and engagement for all students.

For Secondary

Desmos has developed a free online graphing calculator. They also have a Four Function and Scientific calculator available. SBA uses these calculators for grades 6-8, and 11. Many math teachers have already discovered how easy it is to create tables, graphs, and equations.

In addition, Desmos provides a variety of classroom activities that guide students through explorations individually or in teams, along with tools to make your own. Try one out with your classes!

Graphing Stories provides short videos that ask students to graph something against time over 15 seconds. They provide the graphs to graph on, and the videos include one possible “answer.” Discussion of that answer, and how it is different from what students came up with, can be a great opportunity for students to critique the reasoning of others and justify their own thinking.

101questions asks the viewer to identify a mathematical question that is asked by a visual (photo or video). This is the first step in mathematical modeling, and an important habit of mind for using math in everyday life.

The Mathematics Assessment Project (7-12)

The project is working to design and develop well-engineered assessment tools to support US schools in implementing the Common Core State Standards for Mathematics (CCSSM).

The project creates tools for formative and summative assessment that make knowledge and reasoning visible, and help teachers to guide students in how to improve, and monitor their progress.

AlgebraByExample gives students practice solving problems and practice modeling, analyzing, critiquing and articulating mathematical arguments. Math teachers know that some mathematical mistakes are made over and over again. Research suggests these kind of repeated errors are often due to students' underlying misconceptions. Teachers and researchers worked to target students misconceptions, effectively remediate repeated errors, and promote students' spontaneous mathematical discussions. AlgebraByExample helps students identify discuss and reduce misconceptions, deepen correct conceptual understanding and strengthen procedural skills.
