This counseling curriculum guide by Dr. Lisa King is a great resource for elementary and middle school counselors. It can be used in classroom lessons, but I use it with groups in grades 3-5. It is perfect for a small group because you set the stage in session 1 and then select a lesson from the chapter for each of the letters in MINDSET:
Identify how Your Brain Works
Not Yet is OK
Everyone is Unique
Teach What You Know to Others
I use it in my resiliency groups. There are several lessons for each letter so I select the one I feel is most appropriate based on my group members. The book also has bibliotherapy lists, websites, and video clip lists for each chapter.It contains student pre-post tests but I modifed it to allign with the type of perception data ASCA wants us to collect (knowledge, skills, and attitudes) and using an even number scale (no neutral as you have with a 3 or 5 point scale).
