Sponge Activities for High School

[rlbbas123]

I have been looking for extra ideas to keep high school students busy and less talkative during my class time. Most of them work on their assignments, however, when they are done, what are some fun ways to keep them busy and less likely to cause disruptions.
Maybe something everyone would enjoy doing and keep me from looking to corney or someone that doesn't know what they're doing.

You can run off some Suduko or logic puzzles that should do the trick.
