Date: 7/7/96 at 21:35:27 From: John Case Subject: Homeschooling Multiplication I would like more info for my 15-yr-old who can not multiply. I am homeschooling and need help becuase he just can't seem to memorize his time tables and therefore can't divide. Do you have any suggestions? I also have a 10-yr-old and a 7-yr-old. The 7-yr-old is having problems with numbers, too. Thanks Vickie Case

One game which has come highly recommended to us is called 24: players are given four numbers that they must combine using addition, subtraction, multiplication, division, or a combination thereof to bring about the answer, 24. It's sold commercially as a board game. A similar game is Spiro Math, on the Web at: http://users.penn.com/~hank/spiro.html Here are some other ideas about multiplication and involving your family in learning math: Memorization of times tables is very helpful for division, but it's certainly not ESSENTIAL. Rather than focusing on what he *can't* do, why not focus on what your son CAN do? Your whole family might be interested in playing with problems like this one: If you have a family with 5 people, and each person wants the same number of pieces of candy, what size (in pieces of candy) could you family buy? This question has LOTS of answers... Then you can ask: what about other size families? Here are two other examples which convey the idea of multiplication without explicitly mentioning it... - make rectangles out of bingo chips (or rows of anything else) 2 times 5 would look like * * * * * * * * * * or * * * * * * * * * * - think about multiples When you recite lists of numbers like 3, 6, 9, 12, 15, 18.... do you know that you're actually saying 3 times 1, 3 times 2, 3 times 3, and so on? One of the best things to do with math is to get your entire family involved. As a homeschooler, you're lucky to have the opportunity to find math in daily life. Cooking, for example, allows many opportunities to use arithmetic and measuring skills, like when you follow and modify recipes. So do activities like woodworking and gardening. Some of the best mathematics has started in games and recreational puzzles. You might want to try different sorts of puzzles with your family. The Math Forum http://mathforum.org sponsors quite a few puzzles and contests and you can also find interesting puzzles in newspapers, magazines, and books. You can also find lots of fun mathematics on the internet. One of my favorite sites is called MegaMath: http://www.c3.lanl.gov/mega-math/ I hope that these suggestions help... Please let us know if we can help again. -Doctor Jodi, The Math Forum Check out our web site! http://mathforum.org/dr.math/
