/  SAT Math Test Prep (4 of 4): Dinosaurs and Depreciation

#### Objectives

• Students will be able to identify linear and exponential growth and depreciation and solve SAT problems involving them
• Students will practice Algebra 2 skills that occur frequently on the SAT
• Students will know what "super scoring" is and how to plan for it
• Students will know how to prepare well for their actual SAT test day

#### Description

Linear and exponential growth and depreciation are increasingly common topics on the SAT, but for many students, they feel like ancient history because it’s been a while since they’ve seen them in class… we’ll travel to Dinosaur Island to see some real ancient history and learn how to identify these common species of SAT problems. And with the recognition that this is our last class, and test day is coming soon for many students, we’ll discuss how to prepare for the actual day and what to do about things like “super scoring,” so that test day won’t hit them like a 65 million year old comet!

#### Sequence

1. Class will begin on dinosaur island. Students will begin by completing a problem having to do with wildlife and depreciation of camera equipment (SAT Practice Test #7, Section 3, Problem 6)
2. Students will discuss the difference between linear and exponential growth and depreciation
3. Students will then solve a problem that is exponential rather than linear, as the first problem was (SAT Practice Test #7, Section 4, Problem 27)
4. Students will have to solve a problem where the main task is to distinguish between linear and exponential equations (SAT Practice Test #8, Section 4, Problem 15)
5. Students will travel to the Math Lab to do a practice problem (SAT Practice Test #8, Section 4, Problem 37)
6. Students will be given a list of suggestions for what to do on their actual test day, as well as have a discussion about "super scoring"
