Stumbled on this website today, Schools for Hope.

Schools for Hope is a new curriculum project developed by iFred, the International Foundation for Research and Education on Depression. It is based on research that suggests hope is a teachable skill. Our aim is to equip students, educators, and parents with the tools they need to find and maintain hope even during the most trying of times. 

The offer up a 10 lesson curriculum for teaching hope in middle school. Looks great.
