How it works

Short, fun practice that adds up. Kids play; parents and teachers see real progress.

1

Play every day

Daily Crown, live duels with classmates, and practice at your own grade level, with Axiom the AI tutor when you're stuck.

2

Hit your Weekly Goal

50 questions at 75% accuracy or better. Accuracy counts more than speed, so careful work wins.

3

Earn your crown

Climb the Season Mastery Path, compete in Weekly Champions, and earn real rewards your parent approves.

Real rewards for real progress

Earned by learning, never by luck. Every reward goes to a parent's account, and only after they approve it.

Season Mastery Reward

Meet your Weekly Goal 8 times in a season, pass a quick Mastery Check, and choose a $5 reward: a school supplies kit or a gift card. Included with Premium, Family and Max.

Weekly Champions

Every week, in each grade division, the Top Scorer and the Most Improved player each win a $5 reward. Free to compete, no purchase necessary.

MathCoins

Every correct answer earns coins for avatars, titles and Streak Shields. Coins are just for fun and are never exchanged for money.

🎁 How Rewards Work
Your child earns real rewards by learning, never by luck: a Season Mastery Reward (8 Weekly Goals + a passed Mastery Check, included with paid plans) or a Weekly Champions prize (Top Scorer or Most Improved in their division, free to enter). Each reward is worth $5: a school supplies kit or a Target/Amazon eGift Card.

When your child claims one, it shows up in the queue above. Approve or Deny it here. Approving never charges you anything: we send eGift Cards to your account email, or contact you for a mailing address for supplies, usually within 14 days.

MathCoins are just for fun and never turn into money. Official Rewards Rules

Privacy: a reward claim only ever reaches the parent account your child's Link Code connects to, never any other account.
