I printed out the background on cardstock and laminated it. The students then get a back of six green lights (the symbols/pictures), six yellow lights (the definition) and six red lights (the term). They have to match all sets of six correctly. I also created a checklist so they can track their progress.
The students work in groups. They rotate when finished with each stoplight (there are four - Dynamics, Tempo, Articulations/Style, and Misc. Terms).
