Agenda
- Number talk: Visual Patterns — arrows laid tip to tail, growing: where does step land?
- Random groups: the walk in coordinates — add arrows by adding components; stretch them, reverse them, subtract them
- Consolidate: Adding and Scaling Vectors — and which of your arithmetic habits survived the trip
- Preview: a plane flies one arrow while the wind flies another — the sum is the whole story, and a task, on Day 5
Things to do before our next class
- Journal: does vector addition commute? Convince me with a picture, then again with components.
