# MS Math – Nov. 7-11, 2022

6th Grade Math – Mrs. VonFeldt and Mrs. Evans

This week in 6th grade math, we will be investigating rational numbers which include positive and negative fractions, mixed numbers, decimals and integers. We will plot them, order and compare them. We will also learn about absolute values and work problems involving them. Here is a good video about absolute value:

7th Grade Math – Mrs. Evans

In 7th grade math this week we will continue to investigate how to show relationships between two things using rates. We will use what we learned last week about writing rates as unit rates to determine whether relationships are constant (proportional). For those rates that are constant, we will learn to create tables and graphs to show the relationship. Here is a video that describes how to tell if a relationship is proportional:

This week we will come to understand that equations are functions in which we input one variable (usually designated as x), and it outputs a unique value (usually designated as y). We will graph the ordered pairs (input, output) or (x, y) that are solutions to functions, thereby representing the equation on a graph. This is a very useful skill that we will use in algebra. We will finish Chapter 2 this week, with a review on Wednesday and then do a special project in which we will use our new graphing skills to represent real-world relationships on graphs. Below is a website introducing the mathematical concept of functions.

Algebra – Mrs. VonFeldt

This week we will explore linear equations written in slope-intercept form (y=mx + b). If we can find the slope and y-intercept of a line, we can quickly write an equation in slope-intercept form. Conversely, if we have an equation written as y = mx + b, we immediately know the slope and y-intercept of that line. This week, we will also look at direct variation functions which are just linear relationships that have a y-intercept of 0. Many relationships in everyday life vary directly such as cost of gas per gallon, miles driven per hours traveling, cost of bananas per pound, etc. Below is a fun video to help remember the formula y = mx + b:
