Memorizing Multiplication TablesDate: 01/06/97 at 22:20:33 From: Anonymous Subject: I don't know my times! Dear Dr.Math, Hi! My name is Katie. I am 9 years old. I am in the 4th grade. I am having a problem memorizing my multiplication times tables. Do you have an idea how I can do this easily so that I won't forget? Thanks for the information, Katie Date: 01/11/97 at 06:04:58 From: meciru Subject: Problem Ever since I started school I have had a really hard time learning my times tables. What can I do to learn them? I am going into year 6 at a private school. Date: 01/07/97 at 13:13:06 From: Doctor Wilkinson Subject: Re: I don't know my times! Memorizing is hard work. The best way I know is to use flash cards. Get yourself a stack of 3x5 cards. For every times that you need to memorize, write the problem on one side and the answer on the other. Like 4x9 on one side 36 on the other side Once you have made the cards, just keep running through them. If you see 4x9 and you say "36" you turn the card over and see "36", so you can put the card in the pile of ones that you know. But if you say "42" you turn the card over and see that you were wrong, so you put the card in the pile of ones that you don't know. When you've gone through all the cards, take the ones you don't know and go through them again. Don't always do the cards in the same order. Mix them up. If you practice this way I think you can learn them much faster. -Doctor Wilkinson, The Math Forum Check out our web site! http://mathforum.org/dr.math/ Date: 01/11/97 at 06:58:52 From: Doctor Sarah Subject: Re: problem Hi - To help you make up your flash cards, here's a times table: 2 3 4 5 6 7 8 9 10 11 12 2 4 6 8 10 12 14 16 18 20 22 24 3 6 9 12 15 18 21 24 27 30 33 36 4 8 12 16 20 24 28 32 36 40 44 48 5 10 15 20 25 30 35 40 45 50 55 60 6 12 18 24 30 36 42 48 54 60 66 72 7 14 21 28 35 42 49 56 63 70 77 84 8 16 24 32 40 48 56 64 72 80 88 96 9 18 27 36 45 54 63 72 81 90 99 108 10 20 30 40 50 60 70 80 90 100 110 120 11 22 33 44 55 66 77 88 99 110 121 132 12 24 36 48 60 72 84 96 108 120 132 144 Learning multiplication tables can be hard until you figure out your own personal style of memorizing. Some people learn by just looking, some by listening, some by writing over and over. Do you know how you learn best? I always had to say the words out loud, over and over. Eventually they stuck and now multiplying in my head up through 10 goes *much* faster than using any calculator by hand. I never did really practice my 11's or 12's though, so I have to stop and think when I get over 100. (I wish I had learned them up through 20 while I was at it!) I hope this helps. Good luck! -Doctor Sarah, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
