Update: The project described below is on hold. At the moment I’m trying to finish some other courses that will be even more comprehensive and effective. More news soon.
From the Sunday, March 23, 2008 Foxtrot comic by Bill Amend So many people have asked about a sequel for “Numbers Juggling – Times without [...] A fun, easy, nothing-to-buy (as long as you have a deck of cards laying around the house) method to practice multiplication by [...] 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 if [...] Math Mojo has got some surprises for you. New lessons on how to improve your basic math skills, and videos! Professor Homunculus is getting his Video Mojo workin’ to bring you some great new stuff. The first set of videos will be about how to practice multiplication using playing cards. So grab a deck of cards [...] Today a concerned reader took issue with what he understands my methods to be. (See comment #4 at Augends, Addends and the Commutative Law of Addition.) Fair enough, but I think he may have misunderstood my methods. That could, of course, be due to the way I communicate them (or miscommunicate them). First let me say that [...] Recently I got an request to review my booklet, “Numbers Juggling – Times without the Tables.” Request came from Sol Lederman, who runs the “Wildaboutmath” blog. I’d heard that name before, but really couldn’t remember much about Sol, so I checked out his blog to see how serious it was. Wow, it’s a great blog, [...]
original photo from Richard Masoner Edited by Brian Not sure what got me thinking about this today, but I was musing about the commutative property, and how it applies to addition and multiplication. (Yeah, it was a pretty boring morning.) Specifically, I was thinking about the word, “augend”. The augend of an addition problem is [...] I’ve just been perusing a very interesting blog (and a great resource for teachers in public schools). It’s called MathNotations. This post intrigued and annoyed me, though. (Hey, maybe that’s a sign that it is a good blog!) It’s a poll about which method should be used to teach multidigit multiplication, like 48*73, for example. [...] A girl recently asked: “I need help learning multiplication. Can you help me learn to multiply?” Professor Homunculus replied: I have lots of questions to ask you, but first, here is something you can do right away to help you learn multiplication by 2, 3 and 4: Get out a deck of cards. Make sure they are all (52) [...]
In 2000 an 2001, I was an “expert” on a website that helped kids with math problems. Most of them concerned problems they were having in school. I’d like to publish some of the exchanges I had with some of the kids. I must mention some “warnings,” though. These questions were asked by real kids, struggling [...] |
