Dobbins Middle School - 8th Grade Math

Welcome to my 8th grade math blog.


It will serve as my primary means of keeping you informed about your child's math class. I encourage you to visit often to stay abreast as we move through the 8th grade Common Core Georgia Performance Standards (CCGPS).

Week at a Glance: February 24, 2014

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 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:

Mon:
 - Review functions unit
 - Begin functions unit assessment

Tue:
 - Complete functions unit assessment
 - Slope intercept form review
 - Writing & graphing linear equations in slope intercept form
    (from slope & y-intercept, table, verbal description)

Wed:
 - Writing & graphing linear equations in slope intercept form
    (from tables, 2 points, point & slope)

Thu:
 - Writing & graphing linear equations in slope intercept form TASK
   TWMM 2.2 (Day 1)

Fri:
 - Writing & graphing equations in slope intercept form TASK
    TWMM 2.2 (Day 2)

*Students in Advanced Math will also learn to write linear equations in point slope form.
