Graffiti style or Jigsaw style of Cooperative Learning in my own classroom

I think I could use both styles, I would use each for a different lesson. For the graffiti style I think I would use it more for a def. or a theorems. That each group could post their ideas about the lesson/ come up with their own def. and then we could summarize it. I find that this could be used also for solving problem, and many other types.

For the Jigsaw I have done this type of lesson before, but for math I would have to think outside the box a little bit. If it was for sometype of job/career then I think it would be easy that the groups could share and then pair up after.

Overall I think that these are both great ideas, I like the graffiti idea better, and plan on using it more in the future than the jigsaw.
