Math 7 (Class 104)

Lesson Title
No Classes Today-- Languages Project

Overview
In today’s class students work on estimating the measures of angles.
Textbook Sections
Problem 3.2 (Txt. p.25) Estimating Angle Measures

Vocabulary
tiling
regular polygon
polygon
pentagon
hexagon
octagon

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 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.

Math 6 (Class 104)

Lesson Title
Investigation 1: Enlarging Figures

Overview
In today’s class students begin the next unit of study, “Stretching and Shrinking”. In this unit students explore the concepts related to the enlargement or reduction of shapes, scale factors, area growth, and indirect measure. They learn how ratios, fractions, and percents as well as equations, graphs, and tables can help them understand and make predictions in such situations.

Essential Question
How can transformations be described mathematically?
How do different shapes compare to each other?

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

Key Skills
I can use a rubber band stretcher to enlarge a figure.
I can make a detailed list of what is the same and what is different about two shapes.

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 we make an expression or equation simpller?
How can we be sure that we are correct?

Key Knowledge
The factors of an equation can be determined by using an area model.
If the product of two numbers is zero, then at least one of the two numbers must be zero.

Key Skills
I can use an area model to find equivalent expressions.
I can rewrite an equation in a form which is easier to solve.
