Unit 1, Day 4

Agenda

1. Number talk: Which One Doesn’t Belong — four sequences, each heading somewhere (or refusing to)
2. Random groups: march $n$ upward through ${\left(1+\frac{1}{n}\right)}^n$ — the values creep higher; do they creep forever?
3. Consolidate: The Limit — a name for the value a march settles toward without ever needing to arrive
4. Practise: Limits Practice, first set
5. That number your marches crept toward, a little past $2.718$ — remember it; it returns in Unit 2

Things to do before our next class

• Journal: describe a limit from your own life — approaching without arriving — and say what its “value” is.
