Freebie: Medieval Math Cards and Synesthesia

Do numbers have personality and gender to you? Fueds, family trees, romances…sibling squabbles? Or are they just numbers?

This question came up in my Challenge A class, and out of six kids and a few adults, only one kid and one mom didn’t do this. Since I’ve done this for as long as I can remember…involuntarily with both notes/music notation and math/numbers, I sort of assumed everyone did it to some extent (except for Jim because he’s one of those weird spreadsheet people). Obviously, 0 is the patriarch and 1 is his firstborn son who’s been such a disappointment to him. 2 is the matriarch… 7 is the perfect child who drives his siblings crazy because he really shouldn’t be…etc etc etc.

Turns out that’s an actual thing called Ordinal-Linguistic Personification, which is a form of synesthesia. A large percentage of kids do it, but they usually outgrow it. Only 1% of the adult population has Ordinal-Linguistic Personification, so I guess Jim’s not the weird one after all. There are other types of synesthesia too! Some of them I’ve never even heard of:


Grapheme-color synesthesia – associating letters or numbers with specific colors.

Ordinal-linguistic personification (OLP) – attributing personalities or genders to numbers, letters, or days of the week.

Chromesthesia – hearing sounds and involuntarily seeing colors.

Lexical-gustatory synesthesia – associating words with specific tastes.

Auditory–Tactile Synesthesia – Hearing a sound causes a feeling somewhere on your body.

So now I’m super curious about who else is a closet synesthete. 👀


But back to math, this whole number personification thing has made math discussions in class and at home so much more interesting. I was listening to the math map podcast and Dr. Gilpin recommended making your own number cards for quick arithmetic games…it’s hard sometimes to remember what numbers kings and queens are and if we decided aces were high or low. Plus, it would be nice if the cards went up to 15 like we do with skip counting.

Soooo, thanks to the power of the internet and a little late-night insomnia, here are some personified number cards for all your little creative math geniuses (or right-brained ADHD-prone kids). If you want four suites like regular playing cards, print two sets. (make sure you select “fit to page” otherwise your printer will chop off the color). You can make blue cards negative numbers and red cards positive numbers…you can add the red and minus the blues…or multiply and divide. The sky is the limit! (I included a whole list of quick, fast medieval-themed math games that will tempt even the most dysgraphic sensitive kid into doing math…perhaps even liking it)
Enjoy.

Teaching kids to be thinkers: Fallacy Flipbook

The world right now feels a bit like a flamingo trying to put on pantyhose in the dark. Lots of staggering involved. Maybe it’s because I have one kid going through the Fallacy Detective right now, or maybe we’re just in a new season of family dinners where varying opinions, debates, and conversations are flying on a more “oh hey look my kids are actually mini adults now” level and not the old days of “Please put your underwear back on, and no you cannot stick beans up your nose.”

So all that to say, we’re on a logical fallacy kick around here. We find them in movies and ads, we catch each other doing them and we find them in spades on the internet and news. Whether your kids are homeschooled, private schooled, public schooled, or meet under a waterfall in some Waldorf-inspired space, I think it’s safe to say raising discerning thinkers is a high priority for all of us. Equipping them with the tools to think, discern, and pursue truth is like a broken record on the to-do list.

Not that I have anything remotely close to the answer, since persuasive rhetoric is supercharged these days, and we’re just as susceptible as the next person. So this is not a promise for “life-changing” results, but we’ve been enjoying these cards and matching game which you can download here. It’s led to lots of great conversations and I like that the youngest is catching up quicker than his older siblings did.

Or if you feel like supporting a small business, (mine!) you can download the full flipbook for a few dollars here. I made them to be neuro friendly and brain “sticky” in all the ADHD/Dyslexia ways. Even my older kids are picking it up and reading through them….which….let’s just say I’ll take that as a win!
