Getting out of “but the teacher said we have to do it this way” way of thinking is about the best thing you can do for your mental development. Yeah, maybe you have to do it that way in school, to get a grade, but please realize that grading is a way for schools to keep you obedient, not make you enlightened. [...]

Math Mojo will be aimed at helping anyone who either feels a bit intimidated by math, or would like to learn interesting ways to think about some of the math that they already understand. [...] This is a continuation from the previous posts: What if I Fail 9th Grade Math? (Part 1) What if I Fail 9th Grade Math? (Part 2) What if I Fail 9th Grade Math? (Part 3) What if I Fail 9th Grade Math? (Part 4) What if I Fail 9th Grade Math? (Part 5) At the [...] Ostensibly, this has nothing to do with math. But it is good Mojo. Ayelet Waldman has written a book called “Bad Mother.” I read this post on a blog about how to market not-for-profit businesses (something which MathMojo wasn’t designed to be, but has been for much too long a time). The post is about [...] It’s been awhile since I’ve posted here, but I’ve been posting like crazy to the http://mathmojo.com/kenken page. I’ve already got 24 videos up about how to do KenKen®, from simple 4×4 KenKen, to sadistic 9×9 KenKen puzzlers without operation signs. I’m finding that the feeling I get from KenKen is similar to that “numbers juggling” feeling I get [...] Many mathematicians and some math educators are aware that a lot of the stuff that passes for “math” in schools is simply number manipulation, or rote memory of math “facts.” [...] Thought you might enjoy this bit of math “logic.” The previous post was about the value of learning conceptually before you start practicing for skill. There is an alternative argument that argues for the opposite. Many pedagogues try to plead the case that first you must teach the “basics” (meaning the basic skills, like the “multiplication facts”) before you can expect a child [...] There seems to be a big “fight” about “which should you teach first, math skills or math concepts.” A popular example is the “multiplication tables” versus the concept of multiplication (as repeated addition, for example). It’s a pretty good bet to say that when memorizing things it’s easier if you can relate the objects. Like [...] “The essence of mathematics lies in its freedom. - Georg Cantor Not much math this time, but there is a math joke at the bottom. Today is our little dog’s birthday.
