My 10th Grader Can’t Count Coins: Why This Happens And What We’re Trying At Home
The 4-H kid running the lemonade stand at our neighborhood farmers market smiled and waited, but Javi’s ears had already gone bright pink. It was $3.75 for a large cup, and he’d dumped the entire contents of his hoodie pocket onto the folding table: a jumble of quarters, sticky dimes, a few nickels dusted with Cheeto crumbs, and three pennies. He counted under his breath, started over twice, then swept the whole pile back toward himself and held out a crumpled five dollar bill. “Keep the change,” he mumbled, and grabbed the lemonade before the kid could even pull the cash box open. We walked three booths toward the peach crate before he said anything. “This is why no one uses cash anymore. It’s stupid.”
I didn’t make a big deal of it that day, but it stuck with me. It wasn’t the first time. Last fall, when he worked his cross country team’s snack stand at home meets, he always begged the other parent volunteer to handle cash, said he’d restock Gatorade and run orders to the bleachers instead. I wrote it off as teen laziness, or a deliberate choice to avoid boring work. He’s in 10th grade, gets solid Bs in algebra 2, can walk me through solving a quadratic equation when I can’t remember how from high school. It never occurred to me that counting mixed change was actually hard for him, not just something he didn’t want to do.
I mentioned it offhand to his math teacher at parent-teacher conferences a month later, while we waited for the bell to ring between meetings. She just nodded and pulled his file up on her laptop, like she hears this every conference week. She sees a handful of juniors and seniors every year who freeze up during their occasional cash-based budget activity—kids who ace every algebra test but can’t count out $1.25 in change without help. Most of the time, she said, it’s not a sign they’re bad at math, or that they have a serious learning disability. It’s a practice gap.
When I was a kid, I got a $5 allowance in cash every Sunday, paid for my own popsicles at the pool, sorted quarters for my mom’s laundromat runs, counted lunch money out of my backpack every morning. That’s hundreds of tiny, unplanned repetitions, no worksheets, no tests, just regular life. Most teens today have never had that. Allowance lands in Venmo, lunch accounts are loaded online, school parking is paid through an app, even most vending machines take Apple Pay. They rarely touch physical coins long enough to build automatic recognition, and coin values don’t give you any helpful visual clues to fall back on. A dime is smaller than a nickel but worth twice as much, a weird historical quirk with no logical workaround—you just have to memorize it through repetition.
For kids with ADHD, like Javi (we’ve had accommodations for him since 7th grade), the barrier is a little higher. Counting mixed change means holding a running total in your working memory while you sort and identify coins, especially when someone is waiting on you. That cognitive load adds up fast, even if you understand the values perfectly on paper. His teacher said occasionally the struggle ties to dyscalculia, but for most teens it’s just that daily life moved faster than the chance to pick the skill up by osmosis.
I went home that night and dug out the big mason jar of loose change we keep on the shelf above the dryer, the one we dump our pockets into every night and never do anything with. I didn’t announce we were starting “coin practice” — that would have made him check out immediately. The next Sunday, while we waited for pancakes to cook on the griddle, I dumped the whole jar on the kitchen table and said I needed help sorting it to cash in for tomato cages and potting soil that weekend. No quiz, no grade, just a shared chore.
Without framing it as a trick, I pushed coins into four separate piles first: quarters, dimes, nickels, pennies. I said I always do that first, otherwise I lose track halfway through. He nodded and joined in. Ten minutes in, he held a nickel and a dime side by side and said “this is so dumb. Why is the little one worth more?” I told him he was right, it is dumb, just a leftover from old silver content rules no one ever bothered to update. Once, about three weeks in, I caught myself starting to say “come on, this is second grade work” when he mixed up the two piles for the third time. I bit it back. It is second grade work on a quiet worksheet, with no line of people waiting, no sticky fingers, no pressure to get it right on the first try. That’s the part everyone forgets.
We still spend 10 or 15 minutes sorting most Sundays while breakfast cooks. Some weeks he complains, some weeks he puts on a skate podcast and we don’t talk the whole time. No flashcards, no random pop quizzes out of nowhere. I started giving him small, low-stakes real jobs that don’t come with an audience. When we get takeout and I tip in cash, I’ll holler from the kitchen “can you count $3.50 out for the driver while I grab extra napkins?” No one stands over his shoulder, no stranger is waiting, if he has to start over three times no one knows. I showed him the routine I’ve used my whole life: start with quarters, add them until you’re as close as you can get without going over, then dimes, then a nickel if you need it, pennies last. That one small shift—sorting first, counting largest to smallest—cut his working memory load so much he got through a full jar on his own a month in.
That same week, he texted me from the self-serve car wash out by the highway. He and his best friend were cleaning the truck before a camping trip, the bays only took coins, and both their phones had died mid-navigation. He had a cup of loose change from our sorting in his center console, dumped it on the hood, sorted it, and counted out the exact $5 in quarters with no help. The photo he sent was blurry, just a stack of quarters next to a tire brush, but I could tell he was pleased. I didn’t make a huge celebration out of it when he got home, just said it was a good thing he didn’t have to drive 20 minutes across town to an ATM.
He still freezes sometimes, if there’s a line behind him or he’s already flustered from a bad test or a fight with his friend. Last week we stopped at the bakery downtown after school, he tried to count exact change for an oatmeal raisin cookie, got three quarters in and lost his train of thought. He laughed, shoved the change back in his pocket, and handed over a dollar bill. He didn’t walk away red-faced this time, didn’t go on a rant about how stupid cash is. He just said “next time I’ll get it.”
I think a lot of the time, as parents, we expect these small “basic” skills to just show up on their own, because they did for us. We see a teen who can’t count coins and assume schools dropped the ball, or our kid is behind, or we messed up somehow. But most of the time, it’s just that the world changed, and all those tiny invisible practice moments we grew up with don’t exist anymore. No one needs coins to buy a song, pay a bus fare, or get a gumball these days. You don’t realize how much those little moments taught you until they’re gone.
We’re not aiming for him to start paying for everything in cash, or get a job as a bank teller. We’re just aiming for him to not panic if his phone dies and he needs to pay for parking, leave a tip, or help a friend out. Some Sundays he still sorts nickels into the dime pile. Most weeks now, he catches it before I do. That’s enough for right now.
