What do algebra and QR codes have in common? The answer is Slackmath. Developed by Geoffrey Slack, an innovative math teacher, this site contains dozens of PDFs of algebra, geometry and pre-calculus problems next to corresponding QR codes.  It works well with any iOS or Android device, as well as all computing platforms and browsers.

So how does Slackmath work? Select a topic such as Order of Operations from one of 13 skill categories (i.e. Functions, Equations and Expressions) and access the PDF provided. Once the sample problems on the document are complete, the learner can check responses by scanning the QR code—which will not only reveal the correct answers but better yet, a video explanation of how to actually solve the math problems can be viewed as well.

QR Code readers are freely available to any phone or tablet that has a camera built-in.  Not using a device that has that? No problem! Just open the PDF on any device, then click on the QR code to access the instructional video.

Want to see Slackmath in action? Then check out a sample video below.

Slackmath uses QR codes to teach and learn math in a meaningful and engaging way. It’s a pretty simple yet very powerful tool—one that incorporates math, multimedia and mobile technology. Besides that, Slackmath is perfect for learners to practice a variety of math problems and then obtain immediate feedback.  This is a fantastic website and way to integrate smartphone and/or tablet technology into your class to flip your classroom!
