The following interesting story shows how a student solved one of the unsolved problems in math because he didn’t know that it was just an example of “unsolved problems”. A key question is that was he able to solve it if he had known that it was a hard problem to solve?

Sometimes we don’t need to cultivate our students creativity with too much effort. As long as we don’t confine their thinking space with some assumptions or preconditions, we have done a lot!
