What type of learning is it?

Learning-Type Sorter
Sort the worksheet's scenarios into supervised / unsupervised / reinforcement — then flip a "what if" switch and watch the right answer change.
You Are the Machine: Sandwich Classifier
The 20-row sandwich table three ways: numbers only → with labels → with labels and item names.

Points, lines and regions

One Line, Four Ways
Six word problems demonstrated as a graph, a formula, a table of values, and a plain sentence with real units. Adjust one format and observe the others change accordingly
Draw the Decision Line
Separate healthy from not-healthy sandwiches with a line — then state the inequality and count your misses.

Images become vectors

Distance is a choice

One coordinate plane on the projector; every student is a named cursor on it from their own device. Three modes: Cluster Yourselves, Human Coordinate Plane, and Rate & Cluster Movies. It's the one piece that needs a server — see classroom/README.md to run it (FastAPI, one process, no database).
