The sample curricula
Every example on this site uses the same few curricula, so you can follow one lesson from step to step.
Most steps use Math. Its outline goes from Level 2 down through modules, topics, and lessons, and each lesson holds two resources: a Teach Book and an Exit Ticket. Math is only partly in Spanish, on purpose, so some lessons have a Spanish version and some don't. The five Exit Tickets are separate resources that share a title, so the outline names each one with the lesson it's in.
Smaller curricula, each with a single job, appear where a step needs one. More are added as steps are built.
Try it: find which curriculum has a Spanish version, and which step uses Science.
Math carries most of the site. Each smaller curriculum exists for one step, so that step's changes leave Math as every other step expects it. When you meet a curriculum you haven't seen, its step says why it's there.
