Unit Focus:  Linear Functions (multiple representations)

Crosswalk Coach Connection:
 - Lesson 21 - Solving Problems with Functions
 - Lesson 22 - Using graphs to describe relationships (Piecewise Functions)
 - Lesson 23 - Comparing Properties of Linear Functions

This week in math, we will complete our study of linear functions, which includes:
 -- Identifying functions from multiple representations
 -- Distinguishing between linear and nonlinear relationships
 -- Applying function rules
 -- Intro to writing function rules

Since knowledge of functions is imperative to understanding the linear functions unit, students will continue to use and apply those concepts as they learn about linear functions. In the linear functions unit, students will use the slope-intercept form (y = mx + b) to write and graph linear equations from multiple representations, including:

• slope & y-intercept
• rate of change & initial value
• two points
• point slope
• table
• graph
• verbal descriptions / word problem

In addition, students will recognize that that a line with an undefined is NOT a function and therefore, cannot be expressed using y = mx + b.

The focus of this week will be analyzing situations (word problems) and representing them with linear functions. Students will also have to interpret the meaning of the slope and y-intercept in context.

Students need to be familiar with the following terms to improve their success as they progress through the unit:
 1) function
 2) linear
 3) nonlinear
 4) piecewise
 5) domain
 6) range
 7) input
 8) output
 9) slope
10) y-intercept
11) rate of change
12) initial value

The tentative agenda for this week is listed below. This agenda is subject to change based on students' needs:

Mon:
 - Writing linear functions to represent situations. Interpreting slope & y-intercept in context.

Tue:
 - Review linear functions quiz
 - Analyzing situations and representing them with equations and graphs of linear functions.

 - Review linear functions unit
 - Intro graphing piecewise functions

Tue:
 - Linear functions assessment

Wed:

Happy New Year!

This week in math, we will resume working on the Pythagorean Theorem. Before the holiday break, students learned the following:

- The Pythagorean Theorem applies to right triangles angles only.

- It specifies a relationship between the areas of the squares created off of the legs and hypotenuse of a 

  right triangle.

- How to apply the Pythagorean Theorem to find missing side length on a right triangle.

- How to apply the Pythagorean Theorem to solve real-world problems.

After reviewing the items above, we will proceed with the the rest of the Pythagorean Theorem & Volume unit. The focus of this week will be:

- Using the Pythagorean Theorem to find distance in the coordinate plane.

As always, students will have homework nightly (Mon - Thu).
