Making Sense of the Multiplication Table
Visualizing Numbers, Values and relationships with the Math Grid:
My 4th graders viewed math as all about how things are related and these related
things form patterns with each other. That's why the multiplication tables make sense when
you think about it. Each number is just getting bigger by itself, by its
own size. Like 2 gets bigger by 2 creating 2, 4, 6, 8, 10, 12, 14,
and so forth  that's a sensible pattern. We don't try to memorize these
patterns, but we use them so much that they become pictures in our imaginations.
The easiest ones are the Special Squares, the diagonal numbers on the big
grid!
Use a grid like this one to create your own classroom games, puzzles, and
challenges.
For fun, remake this chart and scramble the vertical numbers on the left
side of the grid.
