How to Help Your Teenager With Algebra (When You Don’t Remember It Yourself)
“Can you help me with this algebra problem?”
Your teenager slides their homework across the table. You look at the equation — something about solving for x with fractions and parentheses — and your mind goes blank.
You learned this 20-30 years ago, but you don’t remember how to do it. And even if you did, schools teach algebra differently now. The methods have changed. Your approach might confuse them more than help.
This is one of the most frustrating situations parents face: you want to support your teenager’s learning, to help your child with algebra, but you genuinely don’t remember the math.
Here’s the good news: you don’t need to remember algebra to help your teenager succeed at it. This post shows you how to support their learning even when you can’t solve the problems yourself.
Most adults haven’t used algebra since secondary school. Unless your career requires it (engineering, finance, data science), you’ve probably forgotten:
How to factor quadratics
The order of operations for complex expressions
How to solve systems of equations
How exponent rules work
And that’s completely normal.
The human brain doesn’t retain information it doesn’t use. You’re not “bad at math” – you’re just years removed from regular practice.
Why Your Teenager Needs Your Help (Even If You Can’t Solve the Problems)
Here’s what teenagers struggle with that has nothing to do with knowing algebra:
1. They don’t know how to get unstuck
When they hit a problem they can’t solve, they freeze. They don’t know whether to:
Re-read the textbook section
Watch a tutorial video
Ask the teacher
Work through a similar example
You can help with this – not by solving the problem, but by teaching them problem-solving strategies.
2. They give up too quickly
Teenagers often expect math to “click” immediately. When it doesn’t, they conclude they’re “bad at math” and stop trying.
You can help by:
Normalizing struggle (“Math is supposed to be hard sometimes”)
Encouraging persistence (“Try one more approach before giving up”)
Celebrating small progress (“You figured out the first step – that’s progress”)
3. They don’t know how to check their work
Most students do a problem, get an answer, and move on – even if the answer doesn’t make sense.
You can help by asking:
“Does that answer seem reasonable?”
“Can you plug it back into the original equation to check?”
“What would happen if you tried a different approach?”
4. They lack study strategies
Schools teach math content but rarely teach how to study math effectively.
You can help by:
Helping them organize notes
Teaching them to review mistakes (not just redo problems)
Encouraging spaced practice instead of cramming
What You CAN Do (Without Remembering Algebra)
Here are specific strategies that don’t require you to solve the problems yourself:
Strategy 1: Ask Diagnostic Questions
When your teenager says “I don’t get this,” help them figure out what specifically they don’t understand.
Instead of: ❌ “Let me see the problem” (then panicking because you don’t remember how to solve it)
Try: ✅ “What part are you stuck on?” ✅ “Can you explain what you’ve tried so far?” ✅ “What does the problem ask you to find?” ✅ “Is there a similar example in your textbook?”
Why this works:
Often, students aren’t stuck on the whole problem – just one specific step. By asking questions, you help them identify the exact sticking point, which makes it easier to find targeted help (from a teacher, tutor, or online resource).
Strategy 2: Help Them Find Resources (Without Being the Resource)
You don’t need to know algebra to help your teenager find the answer.
When they’re stuck, guide them to:
1. The textbook or class notes
“Is there a worked example in your book that looks similar?”
“What section is this from? Let’s look at that chapter together.”
2. Online resources
Khan Academy (free, organized by topic)
YouTube (search “[topic] explained”)
Wolfram Alpha (for checking answers and seeing steps)
3. Their teacher
“Have you asked your teacher about this?”
“Could you go to office hours or send an email?”
4. A tutor
If they’re consistently stuck, it might be time for outside help
Even with the best intentions, parents sometimes make things worse. Avoid these:
Mistake 1: Saying “I was never good at math either”
Why it’s harmful:
This signals to your teenager that math ability is fixed and inherited. If you weren’t good at math, maybe they won’t be either.
What to say instead:
“Math is challenging, but you can learn it with practice”
“I didn’t use algebra much after school, so I’ve forgotten it – but that doesn’t mean you will”
“Everyone struggles with math sometimes. The difference is whether you keep trying.”
Mistake 2: Doing the work for them
Why it’s tempting:
You want to help your child with algebra. If you figure out the answer (even by looking it up), you can just show them and end the struggle.
Why it backfires:
They don’t learn. And next time there’s a similar problem, they’re stuck again.
What to do instead:
Guide them to the answer without giving it:
“What if you tried [this method] first?”
“Let’s look at a similar example together”
“Can you try the first step and see what happens?”
Mistake 3: Getting frustrated when they don’t understand
Why it’s harmful:
Your teenager can tell when you’re frustrated. They internalize this as “I’m frustrating my parent” or “I’m stupid.”
What to do instead:
If you’re getting frustrated, acknowledge it honestly:
“I’m having trouble understanding this too — let’s find a resource that explains it better”
“I think we both need a break. Let’s come back to this in 20 minutes.”
Then step away. Frustration helps no one.
Mistake 4: Undermining the teacher’s methods
Why it happens:
Schools teach algebra differently now than when you were a student. You might look at your teenager’s approach and think, “That’s not how I learned it. I can help my child learn algebra with my method.”
Why it’s harmful:
If you teach them “your way” and it conflicts with what the teacher teaches, your teenager gets confused and doesn’t know which method to use on tests.
What to do instead:
Ask: “Is this how your teacher wants you to solve it?”
If your method is different, acknowledge it: “That’s interesting – my teacher taught a different method. But if yours works for you, stick with it.”
When Methods Really Have Changed
Some algebra concepts ARE taught differently now.
Examples:
1. Factoring quadratics:
Old method: Guess-and-check, trial and error
New method: Box method, area models, systematic approaches
2. Solving equations:
Old method: “Whatever you do to one side, do to the other”
New method: Balance scales, visual models, explicit reasoning
If your teenager’s method looks unfamiliar, that doesn’t mean it’s wrong. It might actually be better than how you learned it.
The Exception: When You DO Remember the Math
What if you’re one of the parents who does remember algebra (or you’re an engineer, accountant, or in a math-heavy field)?
You still might face challenges:
Challenge 1: Your teenager doesn’t want help from you
Teenagers often resist help from parents, even when parents are qualified. It’s developmental — they’re asserting independence.
Solution: Offer help once. If they decline, respect it and suggest alternatives (teacher, tutor, online resources).
Challenge 2: Your approach conflicts with the teacher’s
Even if your method is mathematically correct, if it doesn’t match what the teacher expects, it can hurt their grade.
Solution: Ask your teenager, “Is this how your teacher wants it done?” If not, let them use the teacher’s method even if yours is faster.
Challenge 3: You explain it and they still don’t get it
Being good at math doesn’t mean being good at teaching math. Your teenager might need someone with teaching experience who can explain concepts multiple ways.
Solution: Recognize when your help isn’t landing and bring in a tutor who specializes in teaching (not just knowing) algebra.
Building Independence (The Real Goal)
Here’s what matters more than you helping with every problem:
Teaching your teenager to:
Identify what they don’t understand
Find resources independently
Ask specific questions (not just “I don’t get it”)
Persist through challenges
Check their own work
These skills matter far more than solving any individual algebra problem.
By the time they’re in university, you won’t be there to help with calculus or statistics. But if you’ve taught them how to seek help, evaluate resources, and work through problems systematically, they’ll be fine.
Your job isn’t to be their algebra tutor. It’s to teach them how to learn.
The Bottom Line: You Can Help Without Remembering Algebra
You don’t need to remember how to factor quadratics or solve systems of equations to support your teenager’s algebra learning.
What you CAN do:
Ask diagnostic questions that help them identify where they’re stuck
Guide them to resources (textbooks, online tools, teachers, tutors)
Encourage them to explain their thinking out loud
Focus on the problem-solving process, not the answers
Know when to bring in outside help
What you DON’T need to do:
Solve problems for them
Remember everything from your own school days
Be their primary math resource
The most important thing you can offer isn’t algebra expertise — it’s patience, encouragement, and the message that struggle is part of learning.
If your teenager knows you believe they can figure it out (with the right support), that matters more than whether you can solve for x.
