Math 6 (Class 123)

Lesson Title
Investigation 4: Polygon Properties and Tiling

Overview
In today’s class students continue to work toward determining how to predict if a regular polygon with a given number of sides will tile.
Textbook Sections

vertex

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
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

Turn-In (#-1)

Math 7 (Class 123)

Lesson Title
Investigation 3: Patterns of Similar Figures

Overview
In today’s class students extend the work started yesterday on determining if two shapes are similar by visual inspection. Using rulers they measure the lengths of the sides of the pairs of figures they previously identified as being similar, and then calculate the scale factors.
Textbook Sections
Problem 3.1 (Txt. p.28) Identifying Similar Figures

Vocabulary
similar
corresponding sides
corresponding angles
segment
ratio
perimeter

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 can transformations be described mathematically?
How do different shapes compare to each other?
What is required for two shapes to be similar?

Key Knowledge
Certain properties of a shape are maintained when a shape is enlarged or reduced.

Key Skills
I can visually determine if two shapes are similar.
