How to Plan an Effective Math Refresher for Middle School, High School, and Pre-College Students
Last Saturday I wiped chocolate chip cookie crumbs off my kitchen table—there’s a permanent coffee ring near the leg that I’ve given up scrubbing—and pulled three different spiral notebooks out of my canvas tote. One for each student sitting across from me: Lila, 14, just wrapped 8th grade and got a note that her foundational algebra skills weren’t strong enough to start 9th grade on track. Leo, 17, is heading into his final year of high school and needs to fix gaps from sophomore year to hit the score he needs for his engineering program application. Mia, 18, graduated high school three months ago, hasn’t touched a math problem since her final exam, and starts pre-med in the fall, where she’ll need calculus she barely remembers from 11th grade. All three were here for the same thing: a math refresher, not an intensive summer cram to get ahead, just filling in the gaps that pile up over rushed semesters, skipped units, and time away from the classroom.
Lila’s mom originally signed her up for a 4-week intensive, two hours a day, five days a week. By the time they came to me, Lila had spent two nights crying after her first two sessions, saying she “was just bad at math” and wanted to drop the whole thing. She froze when I asked her to combine 3x + 2x, saying she couldn’t remember if she was supposed to add the exponents or just the coefficients. It turned out her teacher had rushed through the end of the year after two weeks of snow-related school closures, so the class only skimmed basic algebraic operations before moving on to functions. Lila had never had time to practice the basics enough to remember them, and jumping straight into 8th grade review just amplified her anxiety.
We cut the intensive entirely. Now Lila does 20 minutes of work four days a week, always before breakfast so it doesn’t hang over her whole summer. We started three grade levels below where she is, working on basic integer operations and fraction multiplication that she’d always been shaky on, instead of jumping straight to 8th grade algebra. I told her mom no quizzing her at dinner, no talking about how “important math is” for her future every other conversation. Just let the 20 minutes happen, then move on with the day. Two weeks in, Lila combined those terms without hesitating last week, and even laughed when I got a problem wrong on the board. It’s slow, but it’s sticking.
Leo came to me with a brand new 500-page math refresher book, spine still unbroken, sitting in his backpack. He’d bought it after scoring 20 points lower than he needed on a practice entrance exam, most of the points lost because he couldn’t remember basic trigonometry identities he’d learned two years earlier. He works 20 hours a week at a local coffee barn, and he told me he couldn’t find three hours a night after work to go through the whole book before fall. He already knew how to solve the hard problems; he just couldn’t recall the basic rules he needed to start them.
We dumped the big book. Now Leo makes 10 flashcards a week of the rules and formulas he forgets most, writes each one out by hand instead of buying pre-made sets, and goes through all of them for 10 minutes every morning while he waits for his coffee to brew. Once a week, he solves one full practice problem that uses all the formulas he’s reviewed. Last week, he texted me a screenshot of his latest practice test: he’d gotten 82% of the trig questions right, up from 28% a month earlier. He still forgets a couple every week, but that’s why the 10 minute daily review works better than a one-time cram.
Mia was the most stressed of the three. She’d skipped her final year of math to take studio art electives she needed for her college portfolio, so it had been almost two years since she’d worked with derivatives and integrals. She’d mapped out a plan to redo all of 10th and 11th grade math in six weeks before her placement test, and she was already two days behind and having panic attacks. We started by pulling the free sample placement test straight from her college’s website, took half of it together, and marked every problem she got wrong. It turned out she only struggled with three specific topics: integration by parts, finding derivatives of trig functions, and graphing polynomials. Everything else she still remembered just fine.
Instead of redoing two years of math, she spends 30 minutes three times a week working only on those three topics, using free Khan Academy videos that match exactly what the college tests for. She took the practice placement test last week and got the score she needs to get into her required calculus class. She’s put the notebook away for the rest of the summer, and she’s going camping with her friends next week.
Over the years I’ve tutored kids of all ages for math refreshers, the biggest mistake I see parents and students make is treating a refresher like a big, intense project that has to cover every topic from the past several years. Most gaps aren’t full years of missed learning; they’re small, wobbly spots that just need a little consistent attention. You don’t need to spend hundreds on a big book or an expensive summer program. Short, consistent sessions focused only on the spots where you actually struggle work far better than long, overwhelming cram sessions.
It doesn’t work every time, of course. I had a 16 year old last spring who tried the 20 minute a day schedule, and he got busy with varsity soccer and stopped showing up after two weeks. We switched to 45 minutes once a week on Sunday afternoons, and that’s worked for him. There’s no one right pace. Right now, Lila, Leo, and Mia are all on track, none of them are dreading their math work this week, and that’s enough. I’ll see them all again next Saturday, same table, same crumbs, and we’ll keep going one small problem at a time.
