I started small groups this week. For my first and second grade social skills group I am using First Steps to Social Success by Diane Senn. There are 25 lessons so I pick 8 lessons for each grade level two from each of the 4 topics covered:
For my third and fourth grade I use Senn's Next Steps to Social Success. These resources have good pre-post tests and handout too. I select lessons from the featured topics in Next Steps:
You could use lessons from both books but I am using them at different grade levels and tracking which lesson I have used. I may need to do a second group later in the year for some of the students and there are still plenty of lesson left.
