Ten calm minutes. Real math. No game. I built Sierra Math for my own daughter's Grade 3 practice, so it's made the way I'd want it as a parent: something you can check once a week and actually trust. No loot boxes. No coin economy. No flashy game loop. Just clear practice, honest feedback, and real progress you can see. HOW IT WORKS Your child picks up where they left off with one clear "Start Practice" button. No menus to get lost in. Each session is 10 questions covering California Grade 3 math standards, mixing multiple-choice and numeric-entry questions. Wrong answers come with a simple, grade-appropriate explanation, not just a red X. Skills are marked mastered only after consistent accuracy over time, not after one lucky session. BUILT FOR FOCUS, NOT DISTRACTION A simple daily streak keeps practice going without turning learning into a slot machine. Small mastery and streak badges celebrate real progress. No points, no store, no currency to manage. Every screen is calm and clear. Kids get an obvious next step. Parents get real signal. FOR PARENTS A clear weekly summary: questions answered, accuracy, current streak, and which skills need more practice. Grade-level progress you can actually read, not a wall of stats. One local child profile. No required account. No login for your kid to remember. Practice works fully offline. No internet connection needed to generate questions. WHY CALIFORNIA GRADE 3 MATH Every skill in Sierra Math is mapped directly to California's math standards and reviewed before it ships. It works well as a homeschool supplement, after-school practice, or a summer refresher, basically anywhere a kid needs steady, standards-aligned reps. Right now we're focused on Grade 3 only, because I'd rather get one grade genuinely right than rush out six that are half-baked. More grades are coming. SUBSCRIPTION Sierra Math offers a free trial, followed by an auto-renewing monthly or annual subscription. You can cancel anytime in your Apple ID account settings before the trial ends to avoid being charged. If you want a daily math habit that feels like practice, not a game, and progress you can actually trust, give it a try.
