Elementary school is not the place to teach thinking - it's the place to teach mechanics, basics, and essential skills needed for thinking. As Box said, schools these days teach emotions, which in the Jungian sense are orthogonal to both thinking AND sensation. One needs to have a very "sensate" curriculum - what can the kids DO, not how do they FEEL or what do they THINK. Those things are not important at an early stage for the vast majority of kids. The less kids think while being in an inchoate, infantile stage, the better.
