**THE OVERLAND TRAIL** Students look at mid-19th-century Western migration in terms of the
many linear relationships involved.

**ALL ABOUT ALICE** The unit starts with a model based on Lewis Carroll’s Alice’s Adventures
in Wonderland, through which students develop the basic principles for working with exponents.

**THE PIT AND THE PENDULUM** Exploring an excerpt from this Edgar Allan Poe classic,
students use data from experiments and statistical ideas, such as standard deviation, to develop a
formula for the period of a pendulum.

**COOKIES** In their work to maximize profits for a bakery, students deepen their
understanding of the relationship between equations and inequalities and their graphs.

**FIREWORKS** The central problem of this unit involves sending up a rocket to create a
fireworks display. This unit builds on the algebraic investigations of Year 1, with a special focus on
quadratic expressions, equations, and functions.
