Question:
I have seen a method of teaching multiplication that used a box and diagonal lines. Do you know what this is called?



Replies:
A discussion of multiplication grids can be found on the following website.

Hear is an excerpt from the web site. "Yesterday¹s Chicago Tribune (9/21/06) ran an article about teaching math in school [registration required to access the Tribune] that included something I¹d never seen before: The multiplication grid.

I don¹t have any idea if this is better/worse/harder/easier, but I just found it interesting. It¹s refreshing to see alternate solutions (grid) to more common approaches (stacked)."

There are 63 comments on this web site regarding this method.
