Unit 4, Day 10

Agenda

1. Number talk: Would You Rather — simple at 6% or compound at 5%?
2. Compare and name it: Interest as a Sequence — simple is arithmetic is linear; compound is geometric is exponential
3. At the boards: the same deposit both ways, over 5, 10, and 30 years

Things to do before our next class

• Journal: the year the two curves separate visibly.
