Watch mastery, not just minutes
The dashboard places each student, tracks skill mastery, and flags who needs help — so you know who to pull.
Built for real instruction
The strongest fit is differentiated independent practice — math centers, early finishers, warm-ups, and homework — while you run a small group.
Adaptive placement
A short diagnostic places each learner, then the ELO engine keeps every kid on right-sized problems — one class can span a wide range.
Mastery by area
A per-student × Common Core area heatmap, plus a "who needs help" roll-up that surfaces struggling, idle, and advanced students at a glance.
Assign to mastery
Assign a level, topic, or standard with an optional due date, and watch students reach Proficient — not just rack up attempts.
Emailless & ad-free
Students sign in with a class code + PIN — no personal details. No third-party ad tracking, ever.
Teaches, not just marks
Every wrong answer gets a worked explanation and a second attempt, so a missed problem becomes a learning moment.
Progress you can export
Class analytics and a CSV export for your records — see time, accuracy, and skill growth across the whole roster.
