I teach Pre-K (4.5-5yo getting ready for kindergarten) and I am genuinely worried for my current group of kids. To give an example, the other day we were doing an open ended craft where they had to make trees out of materials. One boy looked at me and asked how to do the craft I told him to use his imagination! He then looks me in the eyes and goes "how do I do that?". I've also realized that a lot of these kids don't know how to handle boredom or how to play by themselves. So it's not just an academic thing, its a social-emotional thing as well.
