Some problems are worth standing up for. On exploration days you work in random groups of three at the vertical whiteboards, on a problem nobody has taught you to solve yet — that is the point, not an oversight. The technique arrives after the thinking, and in this course the conjectures you raise at the boards are expected to survive cross-examination. Expect to be stuck; being stuck is the work, as Why Struggle Is the Point explains.

Hints nudge; they never march. Ask, and you get a question back — see Getting Unstuck. No solutions appear on these pages, ever: the class builds them together, per Our Classroom Norms.
