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.
