My Teen Cheated Through Two Years of Math and Doesn’t Know the Material: How We’re Catching Up
Last Tuesday, I sat across from my 10th grader at the kitchen table, a half-eaten pepperoni pizza between us, helping him prep for his algebra 2 quiz. I asked him to walk me through finding the slope of a line from two points, and he twirled his pencil for 30 seconds, then dropped it on the table with a clatter. “I don’t know how,” he said. “I don’t know any of this, really. I cheated through all of algebra 1 last year, and most of this year so far. All the tests, all the homework. I just copied it.” Our 6-month golden retriever puppy jumped up and grabbed the leftover crust off my plate right after he finished talking, and I didn’t even chase him. I just sat there, trying to process.
We moved right as 9th grade started, and he missed the first two weeks of school to wrap up the sale on our old house and drive cross-country. When he got into the new school, he was already behind on the first three units, and he was too embarrassed to tell me or his teacher. He said everyone else already seemed to know each other and get the material, and he didn’t want to be the new kid who needed extra help. First he just copied his deskmate’s homework, then used Photomath when the teacher stepped out during tests. He got a B+ in algebra 1, came home with a decent report card, and I never thought to question it. I checked the grade box, marked “good” on my mental to-do list, and moved on to work deadlines and soccer practice.
After he told me, I didn’t yell. I was surprised, and a little angry, but mostly I just felt sad for him—he’d been carrying this for a year and a half, scared every day someone would find out. We sat there for another 20 minutes, him talking through how it started, how it just got easier to keep cheating than to admit he was lost.
The first thing we did wasn’t punish him or schedule a dozen tutor sessions. We started by mapping gaps, instead of assuming he needed to redo the entire two years of material. We pulled all his old unit tests from algebra 1, went through each learning target one by one, and had him work a quick problem to show he got it. Turns out, he actually does okay with linear equations and basic functions—he picked that up from osmosis even when he copied homework, just from sitting in class. The big gaps were quadratics, factoring, and systems of equations, the exact units he missed right after moving. That cut our work from a full year of review down to four big topics, which felt way less overwhelming for both of us.
We settled on 20 minutes of review a day, right after dinner, before he plays video games with his friends. 20 minutes is short enough that he doesn’t complain too much, and long enough to make consistent progress. We use free Khan Academy courses that align exactly to what his old class covered, so we don’t have to buy expensive workbooks or commit to a costly tutor right now (we’ll cross that bridge if we hit a wall we can’t get past, but so far it’s working). Once a week, after he finishes his daily 20 minutes, I ask him to walk me through one problem he just solved, so I can confirm he actually gets the steps, not just clicking through lessons to check the box.
A week after he told me, we went to talk to his current algebra 2 teacher after school. We practiced what he’d say ahead of time—he didn’t need to make a big speech, just say he’d fallen behind last year when we moved, had made a bad choice to cheat, and was now working to catch up, and would it be okay if he asked extra questions when he was lost. The teacher didn’t blow up. She said she’d noticed he never volunteered to work problems on the board even though his test scores were good, and she just assumed he was shy. She gave him a packet of old practice problems for the units he missed, and told him he could stop by before school any day if he got stuck. We didn’t ask her to change his old grades, and she didn’t offer—we all agreed the point is learning the material now, not fixing grades from a year ago.
I’ve talked to a couple of other parents since this happened, and a lot of them say they’d be furious if their kid did this. I get that, but I also get how it happens. I used to just ask “how’s school?” and when he said “fine,” I believed him. Now I know that one small change I’m making even with my younger kid is, instead of asking how it’s going, I say “show me one thing you learned this week.” It takes two minutes, and it gives me a way better sense of what they actually know, not just what their grade says.
It’s been six weeks now. Some days he nails three factoring problems in a row and feels proud of himself. Some days he gets every problem wrong and says this is useless and he wants to quit. He still hasn’t filled all the gaps, and we’ll almost certainly have to keep doing 20 minutes a day through summer break. I don’t know if he’ll ever get that solid grasp of the material he would have had if he’d done the work the first time around, and I don’t know if he’ll end up with a perfect grade in algebra 2 this semester. That doesn’t matter that much to me right now. What I do know is he’s not carrying that secret anymore, and he’s learning more now in 20 minutes a day than he learned the entire year he was cheating. We’re taking it one problem at a time, and that’s enough for now.
