Math Resources for Educators Around the Web

Websites with Resources for Math Educators

NCTM Illuminations logo
The National Council for Teachers of Mathematics (NCTM) Illuminations site includes online manipulatives, games, and interactive tools. Each interactive has the activity, instructions, suggested explorations, and related resources.
For Elementary and Secondary
K-5 Math resources logo
 K-5 Math Teaching Resources provides an extensive collection of free resources, math games, and hands-on math activities aligned with the Common Core State Standards for Mathematics. 
PBS Math at the Core logo
This PBS website has engaging media and integrated activities designed for middle school students of diverse learning styles and backgrounds.
Nrich logo
The NRICH Project aims to enrich the mathematical experiences of all learners through rich math tasks and experiences.
For Elementary and Secondary
NZ Maths logo
The Problem Solving section of the nzmaths website has lessons organized by level and curriculum strand.
PhET interactive logo
A number of free interactive math (and science) simulations are available here through the PhET Interactive Simulations project.
Wild maths logo
Wild maths, from the University of Cambridge, provides games, investigations, stories and spaces to explore mathematics: some have starting points, some a big question and others offer a free space to investigate.
you cubed at Stanford math logo
Dr. Jo Boaler's website,, has many resources for teacher and student learning of mathematics.
For Elementary and Secondary
Bedtime Math logo
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. 
For Elementary
101 questions logo
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.
For Secondary
graphing stories logo
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.
​For Secondary
Which one doesn't belong logo
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. 
For Elementary and Secondary
  Three-Act Tasks are sprinkled throughout the SFUSD Math Core Curriculum. Many educators have shared information about how to implement them online, and more examples of this kind of task. One place to look is Dan Meyer's list of Three-Act Tasks.
