This document discusses different approaches to co-creating with children for design projects. It provides examples of co-creating with kids aged 5-14 for the purpose of understanding how to motivate and encourage learning progress reports. The process involved preliminary research, designing activities at different skill levels, testing assumptions with parents and kids separately, observing kids behaviors, and iteratively improving the process. Key learnings included building rapport, using positive language, adapting activities, and involving parents and rewards to keep kids engaged. The level of involvement and environment should be tailored based on the age and needs.
