Subject: Re: Multiplying and Dividing 2- and 3-digit numbers
I have had a lot of luck with teaching multi-digit multiplicaiton by having the kids work through the sub problems first. This helps them see that a two in the second column is worth 20, not two. It goes like this. 24x13 is actually 3x4=12, 3x20=60, 10x4=40, and 10x20=200 for a total of 312. By having them work through this process, they seem to gain a better understanding of the role place value plays in multiplication. Hope this helps. -Tim G., for the Teacher2Teacher service
