I've been an educator most of my career. Something I hear over and over again is that there is too much math to teach and not enough time. I will admit, the math curriculum is packed full of content, and, although much of the content gets repeated year after year, the level of difficulty increases. A typical grade by grade course of study looks something like this, and most educational jurisdictions follow the NCTM guidelines regarding math curriculum. The curriculum is daunting, even if teachers manage to teach it all, are students learning it?
In these changing times with technology supporting math, how much math should be taught? What's relevant? What's irrelevant? Tough questions but we'd like to hear your thoughts.
