A forum friend posted about her daughter’s adventure in learning the math facts:
“She loves stories and drawing, so I came up with the Math Friends book. She made a little book, and we talked about different numbers that are buddies.”
What Are Math Friends?
“For example: 8, 7, 15
(8 +7=15, 7+8=15, 15-7=8, and 15-8=7)
These guys are buddies. Wherever 8 and 7 are, 15 is there too. And vice versa.
Other number buddies:
6, 7, 13
9, 8, 17
There are more, of course, but these seem to be the ones she struggles with memorizing.
She drew clothes and faces on the numbers (which she would do whether she was supposed to or not!) , and each page had a group of friends.”
Or Try Equation Pictures
Another homeschooler shared how her daughter drew story pictures to help herself remember the math facts. Check out the photos:

One of the worst things about my computer dying is the loss of all my old bookmarks. Once upon a time, a blogger posted the cutest pictures of circular multiplication patterns his son had drawn (using just the ones digit of each answer.) I can’t find where I first saw the multiplication stars, but here is a file telling how to make them (see page 3):
[Tip to my MathCounts students: Try making some of these! They will help you understand the “units digit” puzzles that so often stump you.]
