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 functions and begin on the linear functions unit. The focus of the functions unit was:
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, 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
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:
