"All of these are supplemented by the Singapore Math, but I try to make sure they understand there is a reason to learn the things I teach them, so that when there is something I need to teach them that I do not have a "real life example", they understand that it is necessary even though I may not have an example at hand."My son's willingness to do math (still working on love of math) increased tremendously when I ask him to help me balance the checkbook one evening. He understood that, without math, we wouldn't be able to tell how our spending and our available means correlate. We talked about the costs of overdraft fees, and he was amazed that some people we know routinely generate those due to an unwillingness to confront simple math. That got through.
