Firstly, in the site's main page there would be random missions as a way to encourage children and parents to do them. Otherwise (in the left side of the site) the parents could easily locate the missions separated by categories in the interface (example: missions do be done indoors and missions do be done outdoors).
Missions indoors will have something like "Draw your home's stuff as if they had life and then write something you think they would say to you", now missions outdoors would have something like "Try imitating the forms ofthe clouds that you find most interesting, and if possible, ask an adult to join the fun and ask him/her to draw the forms he/she sees" or "Ride a bike with an adult in any path but imagine that it has many obstacles".
There would be a login option so this way parents could mark the missions that have already been done with their children, like the missions that they liked the most and post photos of accomplished missions. They would also comment the missions (as a way of feedback for the moderators, being evident theirs satisfaction or not by performing the mission) and create new missions for the other participants to accomplish.
These missions although they are in digital media would have to be done outside it, in otherwords, without the help of digital technology. Each mission would have an unique goal but would have multiple possibilities to complete it because the main intention is to use creativity in any ways and encourage children to trust themselves.
