This week in math, we will begin the Functions unit. The focus of the week is for students to be able identify functions from a variety of contexts, including:
- Mapping diagrams
- Sets of ordered pairs
- Tables / T-charts
- Graphs
- Equations
To be successful in the this unit, it is important that students are familiar with the following terms:
Domain
Range
Input
Output
Function
Linear
Nonlinear
Rate of change
The agenda for this week is listed below. This agenda is subject to change to meet students' needs.
TUE
- Intro to functions (discuss / explain terms)
Identifying functions from: mapping diagrams, sets of ordered pairs, tables
WED **short class due to 8th grade writing assessment
- Identifying functions from tables and charts
- Comparing functions represented in different ways
THU
- Identifying functions from graphs
- Comparing functions represented in different ways
FRI
- Identifying functions quiz
- Function machine: exploring function rules

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: January 13, 2014
This week in math, we will complete the Pythagorean Theorem and Volume Unit. Students will focus on reviewing all aspects of the Pythagorean Theorem. In addition, they will recall the concept of volume from previous grades. They will learn and the formulas for volume of cylinders, cones and spheres.
During the latter part of the week, students will be introduced to the next unit, Functions if time permits.
The tentative agenda for the week is listed below. This agenda is subject to change based on students' needs.
MON
- Recall Volume
- Volume of cylinders, cones & spheres (understand & apply formulas)
TUE
- "How full is your glass?" task Day 1
WED
- "How full is your glass?" task Day 2
- Unit review
THU
- Unit assessment
- Intro to functions (time permitting)
FRI
- District Benchmark
- Intro to functions (time permitting)
Week at a Glance: January 6, 2014
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:
- Converse of Pythagorean Theorem
- Using the Pythagorean Theorem to find distance in the coordinate plane.
As always, students will have homework nightly (Mon - Thu).
