Board drawings sit still. Change a parameter and curves, intersections, and shapes move—plenty of “I don’t get it” moments unlock there.
The resources hub groups entry points by theme—geometry, functions, algebra, trigonometry, calculus, arithmetic: pick one, drag, watch.
When it’s worth opening
- Monotonicity, extrema, asymptotes—dragging beats memorizing definitions alone.
- Projecting live “if… then…” in class.
- After class, changing conditions yourself instead of only reading solutions.
Once the idea is clear, write the key line cleanly in the LaTeX editor for the handout or homework. Writing and seeing can stay separate—switch by task.
