For parents of K-12 kids
Homework doesn't have to be a fight.
The worksheet lands, your kid looks up at you, and the method on the page makes zero sense. Been there. KEENUMBERS explains how school math actually works, in plain English, so you can watch the stuck face turn into the 'ohhh, I get it' face.
No account needed. Your child's answers never leave your browser.

See the membership →Sound familiar?
- Your child's homework looks nothing like the way you learned math.
- You're not sure if your child is really on track, or just getting by.
- Tutors cost a fortune, and you're not sure you need one.
You don't need a math degree. You need a clear explanation, an honest snapshot of where your child is, and a plan that fits your budget.

Questions parents ask
Do I need to be good at math to use this?
No. That's the point. Each Homework Decoder explainer shows how the school method works in plain English and gives you one sentence you can say to your child.
Which grades does it cover?
The Homework Decoder covers kindergarten through grade 12, including Algebra 1, Algebra 2, Geometry, Pre-Calculus, and Calculus. The free Grade-Level Check covers grades 1 to 8, plus high-school checks by subject (Algebra 1, Algebra 2, Geometry, Pre-Calculus, and Calculus).
What happens to my child's quiz answers?
Your child's answers never leave your browser. The Grade-Level Check runs entirely on your device, doesn't ask for your child's name, and forgets everything when you close or refresh the page.
How much will the membership cost?
Membership is $10 per month or $100 per year, and one membership covers your whole family.
Is this a replacement for a tutor?
It's a lower-cost way to feel confident helping at home. If your child is struggling a lot, talk to their teacher. A tutor can still be a great addition.
