Numberless word problems

Help students overcome the “words” of word problems by removing the numbers. Organized by CGI. A ready resource for all teachers.

Which one doesn't belong

Find the one image that doesn’t fit with the other three. Every image has the potential to “not belong.” Scroll to the bottom of the homepage for links to related sites.

Open Middle

Challenging math problems to get students thinking! The tasks have a final correct answer, but there are multiple ways to approach and solve the problem. Organized by grade level.

  • Problem based learning with 3 Act Tasks
  • Progression Videos – short videos that show content across grade levels.

Math is figure out able Pam Harris

Podcast from Pam Harris that will get you excited that math is not just mimicking procedures and steps but figure outable and kids can do it! Get students “thinking” about math not just “doing” math.


Virtual manipulative site with applets for geometry, algebra, numbers, fractions, probability and data, and a few more goodies listed as “games and applications”.

mashup math

Math Puzzles for all grades. Activities Include: Number Sense, Two Truths, and a Lie, Which One Doesn’t Belong, Think Notice and Wonder, Riddles, Puzzles, Brain Teasers and so much more!

PhET Interactive Simulations,prototype

Phet provides fun, free, interactive, research-based mathematics (and science) The simulations are written in HTML5 (with some legacy simulations in Java or Flash) and can be run online or downloaded to your computer. All simulations are open-source simulations.

Which one doesn't belong

Find the one image that doesn’t fit with the other three. Every image has the potential to “not belong.” Scroll to the bottom of the homepage for links to related sites.

Estimation 180 by Andrew Stadel

Over 200 images where students must estimate the answer to the visual scenario. Examples include height, length, weight, and time. Some images have a reveal-the-answer video.


Applets cover algebra, geometry, measurement, number sense, operations, and probability and statistics. Use the applets in your lessons as warm-ups, starters, explorations, practice, exit tickets, etc. These resources are continually being added to, updated, and improved.

Math Medic

Each lesson begins with students working collaboratively in small groups through a sequence of carefully crafted questions that slowly build in complexity (Experience First). Following this activity, the teacher facilitates a discussion connecting students’ ideas with academic vocabulary and notation (Formalize Later). This approach encourages students to build strong math identities and take an active part in mathematical sense-making.

Desmos Classroom

Explore the Desmos Classroom platform’s free digital lessons and lesson-building tools

GeoGebra GeoGebra - the world’s favorite, free math tools used by over 100 million students and teachers

“An Oldie but a goodie” - This website just keeps getting better and better. They have organized their resources to make them easy to use. The lessons can be sent to the class and monitored in real time – like Desmos but different.

Mathigon's Polypad

The most dynamic and versatile math tool I have seen in years! It can be structured so individual sheets can be sent to students as an assignment. It is imbedded in Desmos as a tool as well.

Illustrative Mathematics

A problem-based core curriculum built on the principle that all students are capable learners of grade-level mathematics. Students learn math by doing math. They are encouraged to use their current understanding of math, their lived experiences, and the world around them as resources for problem solving.

Open Middle

Challenging Math Problems worth Solving. Challenges Sorted by grade and standards.

Math Warmups by Geoff Krall
Emergent Math

Forgive me – but if you are doing test prep questions as bell ringers – you are wasting time – Try these if you want meaningful math at the start of class.
