Unit 2, Day 6

Agenda

1. Number talk: Estimation Duels — how many folds to reach the moon?
2. Random groups — build a table for $2^x$ by hand to $x=20$, then argue about what the graph must do between the integers
3. Consolidate: why the domain is every real number, and what that means for a table that only has whole numbers in it

Things to do before our next class

• Journal: what $2^{1.5}$ means, in your own words.
