This teacher handbook provides guidance on having students participate in the Quest2Matter program to share their ideas for solving problems. It instructs teachers to ask students what matters to them, what about it breaks their heart, and how they could change that. Students then develop an idea and action plan to solve the problem and document their submission. Teachers are encouraged to have students submit their work through the Choose2Matter website or partners to inspire others and potentially have their quest highlighted or be honored for their efforts in changing the world.
