Slackmath makes Algebra Interactive with QR Codes

I came across this posting in my weekly updates from Richard Byrne on his wonderful Free Tech for Teachers Blog. You can go to the website It features a a series of Algebra lessons and you can search by topic from the drop down menu. Once the student completes the problem they can scan a QR code to view a video explanation of the solution. Great idea for “flipping” your algebra class.
