I thought I was all snazzy when I labeled my clock with 5 minute intervals, but this teacher has taken things a step further by wrapping colored plastic wrap and labeling it with fractions and decimals. Even if you don't teach math at that level, it would still be beneficial to create the quarter hour visual.
Suggestion: Team up with 3 colleagues who may also be interested in doing this in their classroom and each purchase one color of plastic wrap.
