I put them in groups and assigned one problem per group (making sure that if a student was in one of the word problems, s/he was in the group working that same question). Answers are included so the kids could check themselves easily. Then I had them make a poster. These are some from last year:
Afterwards, I asked the students to read the other problems and then use the posters to write the solutions in their notebooks.
Here are the problems I used (I'm sure I stole several of them from other people, so let me know if I owe you credit). I always change the names for each section.
