I have always used arrays to demonstrate multiplication of math facts up to 9 X 9 but I would draw the dots or use actual objects to represent each number - didn't work very well with large numbers. .
At my math course, we used base ten blocks to multiply 22 X 26. Make a rectangle with 22 units one direction and 26 the other way. Essentially, we made our array out of base ten blocks. This did not take long at all as we filled in as many hundreds blocks as we could first, then tens, then ones.
