SENSIM MATH · STAGE 3 — BEYOND THE CURRICULUM
The problems school never assigns
Counting without missing a case. Finding the rule behind a pattern and pushing it far ahead. Spotting what holds still while everything else moves. No textbook unit teaches these, and every contest assumes them.
Where Depth takes the school curriculum one level deeper, Reasoning steps outside it. A kid who handles Depth comfortably will still meet unfamiliar shapes here, and that is the point. This is the floor Competition stands on.
453 problems, grouped into 8 kinds of thinking. Free to solve, no account needed.
