To help make the playing of musical cues easier in your classroom, try the one-page PowerPoint show found below.
Whenever you need a quick cue, just activate the page and double-click one of the speaker images. The song will play but nothing else after it. What this means is that you can start the song--or have a student do it for you--and then walk away.
To sample one of the songs, click on the speaker above The Game is On. (Bottom-right corner.) Available on FreePlayMusic.com, that song alone is worth the download.
The PowerPoint show is a big file but you'll find it rather nimble once you've added it to your desktop. Have fun.
