Is AI doing to student writing what calculators did to mental math—and does it matter? A teacher explains
The peppermint tea in my mug had gone cold an hour earlier, and I was halfway through grading 28 10th grade personal narratives when Mia knocked on my classroom door. She pulled the strap of her backpack higher, twisted the cord of her phone around her finger, and admitted she’d used AI to draft her essay about moving across the state the year before. “I changed almost everything,” she said, staring at her scuffed white sneakers. “But I still feel like I cheated. Is that bad?”
I thought immediately of Mr. Hale, my 8th grade math teacher, who sent me to the principal’s office in 1999 for bringing a scientific calculator to a basic algebra quiz. “Calculators will rot your ability to do mental math,” he’d yelled, slamming my calculator on his desk. “You’ll never be able to buy a gallon of milk without pulling out a machine to tell you if you have enough money.”
Thirty years later, I still can’t do long division quickly in my head. I use my phone to calculate tip at restaurants, add up my grocery cart to stay on budget, and even convert ounces to cups when I’m baking. But Mr. Hale’s worst fear never came true. I don’t struggle with managing money, or figuring out if a sale price is actually a good deal. We just stopped wasting class time drilling 100 multiplication problems a day, and started spending that time talking about how to use numbers to solve actual problems. That same shift is happening with writing and AI right now, and most of us are panicking about the wrong thing.
After Mia left, I opened an email from a parent whose son is in my class. He’d found out his 10th grader used AI to write a book report on The Giver, and he was furious. He was ready to make his son stay home from a weekend camping trip to rewrite the whole thing from scratch, and he wanted to know if I supported that.
I wrote him back and told him what I tell all parents who ask me this question: skip the full rewrite, and try one small thing first. Sit down with your kid, pull up the report, and ask two questions: “What’s the main point you wanted to make here?” and “Show me which part of this you wrote that feels most like you.” That’s it. No yelling, no immediate punishment. He wrote back three days later to tell me it worked better than he expected. His son, Javi, admitted he’d gotten stuck trying to start the report after spending a whole week thinking about how the book connected to his grandma’s dementia. AI wrote the basic outline, but he’d never gotten around to adding the part about his own experience volunteering at the community garden. He ended up rewriting three paragraphs that night before the camping trip, no complaints, because it was his idea.
This is exactly the same conversation we had about calculators 40 years ago. Back then, we confused the tool with the skill. We thought the point of math was being able to crunch numbers fast in your head. But the real point of math is being able to understand what numbers mean, and use them to make decisions. With writing, we’ve been confusing the tool with the skill for a long time too. We’ve focused so much on grammar, structure, spelling, and getting a first draft perfect that we forgot the real point of writing is figuring out what you think, then communicating that to someone else.
Does that mean AI doesn’t pose any real risk? No, of course not. If a kid never practices writing their own thoughts down from scratch, they never learn how to sort through messy, half-formed ideas to get to the point they actually want to make. It’s the same as mental math: if you never practice estimating a sum in your head, you can’t tell if the number your calculator spit out is wrong. If you never practice putting your own ideas into sentences, you can’t tell if what AI wrote actually says what you want it to say. That’s the part that matters, not whether you use the tool at all.
Over the last year, I’ve adjusted how I assign writing in my classes, and I tell parents to try these small adjustments at home too. For middle schoolers just learning to structure essays, ask them to write their full first draft by hand, no AI allowed, before they pull up any tools. That 10 or 15 minutes of getting their messy thoughts on paper is where the thinking happens. AI can come in later to fix awkward phrasing, brainstorm additional points, or edit for grammar. For older kids, instead of banning AI, require them to turn in a short “editor’s note” that says what part of the writing they did, and what part AI helped with. It’s not about catching cheaters, it’s about making them think through their own process.
I hung Mia’s narrative on the bulletin board by my desk this month. The line AI wrote was the generic opening paragraph, but the whole middle and end is all Mia: the smell of her grandma’s lavender soap on her old curtains, the way she left her cat’s frayed climbing tree by the dumpster because their new house didn’t have a spot for it, the way she still misses it even though she likes her new town better. A few kids stopped after class last week to say they’d gone through the same thing when they moved. None of that would have happened if AI had written the whole thing. But none of it would have happened as quickly if Mia hadn’t used AI to get past that first stuck spot, either.
We’re still figuring this all out, same as we did with calculators. I still make my students do 5 minutes of free writing without any tools every week, to keep that skill sharp, just like my college math professor made us do quick estimates before we used our calculators. But I don’t send kids to the office for using a tool anymore. The thinking is still up to them. That’s the part that never changes.
