# MS Math – Week of Nov. 28 – Dec 4, 2022

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

This week we begin Chapter 4, in particular, we will investigate and extend our understanding of ratios and rates. A ratio is a comparison between two quantities and a rate is a comparison between two quantities that have different units. We use rates and ratios in everyday life, like when we discuss the cost per pound of apples or the miles per gallon that our cars are capable of giving. This week, challenge your 6th grader to notice rates all around them! Here is a summary show the difference between ratios and rates:

7th Grade Math – Mrs. Evans

In 7th grade math this week we will begin to use percentages in more complicated and useful ways that we have in the past. As percentages surround us, this will be a very applicable set of lessons. We will need to be able to move between fractions, decimals and percentages fluently in order to work these lessons well. Here is a review of how make these simple transitions:

8th Grade Math – Mrs. Evans

This week we will continue to practice using the laws of exponents that we learned last week. We will also learn how to write very large and very small numbers using scientific notation. We will then practice using roots and squares in expressions. We will finish the week with a heavy quiz on Friday. Here is a good video about scientific notation:

Algebra – Mrs. VonFeldt

This week we continue to use linear equations in all ways. We will learn how to write equations in different forms such as slope-intercept, standard, or point-slope form. We will also look at how to rewrite equations to go from one form to another.

It is important to learn to apply linear equations to real-life situations. A slope represents the growth of the function or a rate of change. Examples include miles travelled per gallon or a cost per unit. The y-intercept represents where a functions begins. Examples include one-time fees paid or the amount in a savings account before monthly saving. We will continue to include problem solving examples to demonstrate how Algebra is applicable to real life.
