After getting a printed set of factorization diagram cards, I decided there were a few design tweaks I wanted to make. I’ve gone through a few iterations and I think they are definitely better now. Here are some representative samples (namely, 6, 13, 21, 29, and 30):
The changes I made include:
- Better color scheme (at least I think so!)
- Primes now have a visual representation that does not depend on color (though the color is still meaningful). For example, 29 is represented by an outer shell with two half-circles (representing the 2) and a trio of triangles (representing 9, that is, three threes).
- The triangle representing 3 is flipped upside down so it never intersects with anything.
I’d love to hear any and all feedback! Modulo any final tweaks I plan to make sets available for purchase soon.
