FOR PARENTS
What this site actually does
Practice built on real standards, that explains every answer, adjusts to your child, and never leaves them stuck — even when they say "I don't get it."
🎯
Standards-basedBuilt on Common Core, NGSS, and C3 standards used nationwide.🧠
Shows the whyEvery wrong Math answer comes with a clear, step-by-step explanation, not just a red X — many are illustrated with a picture too.🤔
Never leaves a student stuck"I Don't Get It" breaks down Math skills and reading comprehension from scratch, in a topic your child actually likes, one tiny step at a time. More subjects are on our roadmap.🎚️
Meets them where they areSmart Practice quietly moves up or down as your child answers, so it's never too easy or too hard.📊
You see the real pictureA parent dashboard shows what's going well, what needs work, and one thing to try at home.🔒
Safe by defaultNo ads, no chat, no strangers. Your child's data is never sold.
How we build and check every question. Each question is written to a specific national standard (Common Core, Next Generation Science Standards, or the C3 Framework) and passes an automated quality check — one clear correct answer, age-appropriate language, no unsafe content — before it's published. We do not claim alignment to any individual state's standards or tests. This is practice to build skills and confidence alongside school, not a replacement for classroom instruction or a diagnostic assessment. New parent accounts confirm they've read this notice when they sign up.

Good to know. Paid checkout is not open yet. A free 7-day trial is available right now, no card needed, so you can try Individual- and Family-level access before anything opens for payment.
Canceling stops future renewal and does not delete learner profiles or progress. Questions about billing or refunds go through Contact. Read how we protect children on the Privacy page.
Interested in the Family or Classroom plan? Tell us on the Contact page and we will let you know when it opens.
How does the free trial work?
Sign in with a free parent account and press "Start my free trial." No card is needed. For 7 days you get unlimited practice, every Hard question, and Smart Practice. It does not renew into anything, and you can use it once.
Why is Family so much cheaper per learner than Individual?
Individual is priced for exactly one child. Family is built for households with more than one, so the per-learner cost drops the more children you add, down to about $3.00 a month per learner with 5.
Can I switch plans later?
Yes. You can move between plans, or between monthly and annual billing, at any time once paid plans open.
What does "learner" mean?
A learner is one child with their own stars and progress. The Family plan covers up to 5.
Is my child's information safe?
We keep only what is needed to save practice progress, never show ads, and have no chat. See the Privacy page for details.
How is the content checked?
Every question is checked by an automated quality process (a single correct answer, age-appropriate language, and no unsafe content) before it's published. Spot something that looks off? There's a 🚩 report button on every answer page — we read every report.
