As the students work steadily, the sounds of calculators can be heard.
Tap-Tap-Tap
Desk and chairs sound as their occupants shift into a more comfortable position.
Squeak-Squeak-Squeak
Pens being used furtively can be heard making small but loud noises.
Click- Click- Click
Sounds fill the room in chorus, making a silent song.
Fingers snapping, feet bouncing, calculators tapping, chairs squeaking, pens clicking, peers whispering.
Snap-Bap-Tap-Squeak-Click-Whisper
((Definitely not my best, but I was bored in math one day.))
