Algebra 2 (Class 61)

Lesson Title
3.1.6: What’s the connection?

Overview
In today’s class students continue to develop their fluency in moving from one representation of an exponential relationship to another. As time permits students will use their knowledge of linear equation to help develop algebraic strategies for finding linear and exponential functions. They will also learn more about working with roots and exponents.
Textbook Sections
3.1.6 (Txt. p.138) What’s the connection?

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?
How can I find an equation for an exponential situation?

Key Knowledge
Exponential growth is caused by a constant multiplication.

Key Skills
I can find an equation for an exponential function when given a graph, a table, or a situation.

Math 6 (Class 122)

Lesson Title
Investigation 4: Polygon Properties and Tiling

Overview
In the last class students investigated how they could predict whether or not a regular polygon could be used to create a tiling. They decided that it would be good to collect more data, in particular they wanted to see if a regular 9-gon would tile. Hence students began creating regular 9-gons. In today’s class students will use their 9-gons and continue to investigate the requirements that are necessary for a regular polygon to tile.
Textbook Sections
Problem 4.3 (Txt. p.46) Back to Bees!

Vocabulary
tiling
regular polygon
polygon
pentagon
hexagon
octagon
angle ruler
precisely
vertex

Key Attitudes

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
Why do we compare contrast and classify objects?
How do decomposing and recomposing shapes help us build our understand of mathematics?

Key Knowledge
An angle can be measured with an angle ruler.

Key Skills
I can find the sum of the interior angles of any covnex polygon.
I can justify the sum of the interior angles of a polygon by using previously agreed on facts.
I can use what I have learned about the sum of the interior angles of a polygon to develop a method for finding the sum of the interior angles of a polygonal star.
I can draw a regular 9-gon
