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).

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

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).

Week at a Glance: December 2, 2013

Current Unit / Focus: Unit 2 - Algebraic Equations (including special cases)

Unit Standards: MCC8.EE7

This week in math, we will complete the equations mini-unit. We will begin the week with a quiz to allow students to demonstrate their ability to solve multi-step equations. We will review the quiz to reinforce previously learned concepts before moving on to solving equations with variables on both sides and exploring special cases (all real numbers and no solution).

See the outline below for this week's agenda: (This agenda is subject to change based on students' needs).

Mon --> Review solving multi-step equations
              Equations Quiz
              Modeling equations (intro to variables on both sides)

Tues --> Review Quiz
              Solving equations with variables on both sides

Wed --> Exploring special cases (all real numbers & no solution)
              Equations Task Day 1

Thu --> Equations Task Day2

Fri --> Equations Assessment

Tuesday, October 22, 2013

Week at a Glance: October 21, 2013

This week in math, we will work on scientific notation. Specifically, students will learn the following about scientific notation:

- Form (proper form) and function (when, how it is used in real-life)
- Converting: standard form <--> scientific notation
- Ordering & comparing numbers in scientific notation
- Performing operations / computation on numbers in scientific notation

To be most successful with these standards, it is important that students are familiar with the following terms:

* Coefficient
* Power of 10
* Base
* Exponent

We will continue to reinforce the properties of exponents as we study scientific notation. Students will be asked to make connections to the properties as they work with numbers in scientific notation.


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

MON:
 - Intro to Scientific Notation
 - Converting Scientific Notation --> Standard Form

TUE:
 - Practice with Scientific Notation
 - Determining if numbers are expressed in proper scientific notation

Week at a Glance: October 14, 2013

Current Unit / Focus: Unit 2 - Properties of Exponents / Scientific Notation
Unit Standards: MCC8.EE1 /MCC8.EE3, MCC8.EE4

Crosswalk Coach Connection:
 -- Lesson 6 - Exponents

This week in math, we will continue to progress through unit 2 by completing our study of integer exponents and beginning our study of scientific notation.

During the beginning of the week, we will explore powers of 10 to make sense of the final 2 properties of integer exponents:  Zero Exponents and Negative Exponents. We will also work on using all of the properties to simplify exponential expressions and write equivalent expressions.

Students will have 2 tasks to complete to demonstrate their knowledge of the properties of integer exponents:
             * Properties of Exponents Flip Book (Assigned on Monday - Due on Thursday)
             * Properties of Exponents Bubble Map (Assigned on Tuesday - Due on Friday)
These tasks will count as a summative grade and will not be accepted late. They are to be submitted no later than the end of homeroom on the due date.

Students will / have received rubrics to outline the requirements and grading for each task. Ask your child to show you their rubric so you can help them assess their work before it is submitted for a grade.

See the outline below of this week's agenda. The agenda is subject to change based on students' needs.

==============================================================
Advanced Math

Students in advanced math will focus on the same standards this week; however their assignments are somewhat different. Also, since they have moved through the properties of integer exponents a little bit more quickly, they will move on to scientific on Wednesday instead of Thursday.

Advanced math students have also been assigned 2 tasks to demonstrate their knowledge of the properties of integer exponents. Their tasks are:

 * Properties of Exponents Tree Map (Assigned Friday - Due Wednesday)
 * Properties of Exponents Bubble Map or Video (Assigned Monday, Due on Friday)
These tasks will count as a summative grade and will not be accepted late. 
They are to be submitted no later than the end of homeroom on the due date.
