Algbera 2 (Class 53)

Lesson Title
3.1.3 How does it grow?

Overview
You may have heard the expression, “Money does not grow on trees.” However, money does, in a sense, grow in a savings account. In today’s lesson you will apply your understanding of exponential functions to solve problems involving money and interest.
Textbook Sections
3.1.3 (txt. p.125) How does it grow?

Vocabulary
interest
simple interest
compound interest

Key Attitudes
Willingness to work as a group to help meet individual and group goals.

Enduring Understandings
Change is fundamental to understanding functions.
Mathematical relationships can be represented in 4 main ways: Graphical, Numerical, Algebraic, Verbal (written and oral).

Essential Question
How does it grow?
How is the rate written as a percent? As a decimal?
How is it the same or different?

Key Knowledge
Exponential growth is caused by a constant multiplication.

Key Skills
I can determine the percent by which an investment is growing when given a table of values.
I can determine if a sequence is arithmetic, geometric, or neither.
I can write and equation to represent an investment.
I can tell the difference between simple and compound interest.
I can use tables, graphs, and equations to decide on the best offer.

How do decomposing and recomposing shapes help us build our understand of mathematics?

Key Knowledge
An angle can be thought of as the result of a turning motion, a wedge, or two sides coming together to form a common vertex.

Key Skills
I can sketch, and determine the angle measure, of an angle created by turning a fractional amount of a right angle turn.
I can sketch, and determine the angle measure, of an angle created by turning a fractional amount of a given angle.
I can determine the size of the angles of the vertices of shapes A, B, D, M, R, and V in the shape set.
