Habit of "Happiness" in "Homework"

This week I am participating in a retreat called the 'Integrated Ethics Institute' and our topic is the "Habit of 'Happiness.'" I am working through some ideas about how to help my 5th grade math students next year break previously held conceptions of homework and find meaning in engaging in mathematical thinking outside of the classroom. The first image below is a brainstorm I did in MindNode Lite, and the second image is an arrangement of those ideas in Easel.ly.
