Also, be sure to check out the Math Talk section to connect with other educators.

Math Pickle: Is a free site that offers dozens of fun and challenging math puzzles for students of all ages. The puzzles are designed to foster collaborative problem solving over the course of 45 to 60 minutes. Almost all of the puzzles are presented as a series of small, connected problems that students need to solve to complete the puzzle presented to them. The puzzles can be viewed as slides and or downloaded as PDFs.

MathsBot: Tools for math teachers, including bell-ringers and drills, math tools and manipulatives, question generators, printables, and puzzles. (grades K-12)

PBS Math Club: From PBS Learning Media, middle schoolers will love this entertaining video blog. Not only does each episode cover Common Core Standards, it makes math learning culturally relevant with pop-culture references. (grades 6-9)

Photomath: Was the first app to let students snap a picture to get the answer to a math problem. It will not only show students the answer it also shows the steps required to solve a math problem. Photomath is available for Android and iOS.

Quizlet: Students can create study flashcards, play learning games, practice skills, collaborate with other students, and more. (grades 5-12).

Real World Math: This site is intended for educators who are looking to extend the concepts presented in a traditional math curriculum by integrating Google Earth. Currently focused on middle school math or above, this site includes lesson plans, examples, and downloads for mathematics that address standards while encouraging higher order thinking skills and complex problem solving. Their video promotion gives a good overview of the potential for using Google Earth in math instruction. Although a subscription to full access of Mathalicious is $20, the free lessons and activities alone are worth a look. Mathalicious provides lessons and activities based on real-world contexts with a sharp and creative presentation.

Study Geek: Mathematical vocabulary is fundamental to understanding math. Study Geek is a great learning tool that has an alphabetical glossary of thousands of math vocabulary words.

VirtualNerd: More than 1,500 video lessons ranging from middle-grade math through algebra 2. (grades 6-12) .

WolfRam Alpha: Promotes itself as a “computational knowledge engine.” Rather than a search engine that sifts potential sources to provides links, WolfRam aims to be the largest collection of internal computational knowledge on the internet. While many math and science educators have avoided Wolfram in the past due to its quick-answer provisions, WolfRam’s recent upgrades have introduced a fundamentally new way to explain concepts and ideas. Check out WolfRam’s Example by Topic page to browse through all that you can learn from this powerful resource.

Wolfram MathWorld: The Web's Most Extensive Mathematics Resource. As a more focused extension of the WolfRam Alpha computational engine, WolfRam MathWorld provides a concentrated mathematics resource. Thousands of mathematical educators over the course of the past decade developed this tool for application within the math classroom. Be sure to check out some of MathWorld’s Interactive Entries, updated and contributed on a daily basis.

Would You Rather? Is a website maintained by John Stevens for the purpose of sharing quick and fun math challenges for students. Would You Rather? presents a picture with a mathematics problem that asks "would you rather?" Most of the questions have a financial aspect to them. One of my favorite examples is this challenge that asks "would you rather go on a 5-minute shopping spree in the store of your choice or get a $2,000 gift card to the store of your choice?" Would You Rather? offers a simple worksheet that your students can use to analyze the choices presented to them in the challenges.
