Often, teachers will set up situations that aren't announced to the kids as challenges but nonetheless serve as covert challenges. For example, in some corner they bolt down a cage with a wire mesh door. Place some shelves inside and introduce it as storage space where stuff is put away. The next day, load it with some interesting snacks or toys that kids would love to get their hands on. The teacher tells the kids that the stuff inside the cage is for them but unfortunately the key has been lost. Leave the kids alone with the cage for a while. Ideally, they would brainstorm ideas and eventually build some kind of a tool made from other toys and use it to reach stuff on the shelves inside the cage. If they do, report it to the parents as spontaneous creative/collaborative problem-solving. Praise the kids to the parents where they can "overhear" it. Make sure they remember it as a win based on collaborative problem-solving.
