Step 1 · Sort the components
39 components of a tree system, five categories. Drag each one to where it belongs, then check your answers.
Start the card sortStep 2 · Arrange and link
Open the whiteboard and you'll get your own copy of the tree with every component as a colour-coded sticky note. Arrange them so their positions make sense — inputs arriving, outputs leaving, stores inside — then draw arrows to link them logically.
