Fractions are probably the math concept that my students tend to struggle with the most - whatever age they are. So what if we turned fractions into the pieces/tools necessary to do something fun - like play music? Based on a typical digital music editor, just click the different fractions once to pick them up, then drag them over the timeline and click to place them. Click the "reset" button to clear out any of the timelines. Please comment with feedback to help me turn this bare-bones prototype into a fully-functioning teaching app.
