MS Math – Week of Jan. 9-13, 2023

Tuesday is our first Winter Sports Day! See you on the ice or snow!

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

We will continue to learn about percentages this week. Last week we discovered how percents are just another way to write a fraction, decimal or mixed number and that we can convert between one form of the number and another with simple steps. We will want to be able to take these steps fluently and without error so that we can use percents effectively. This week we will use percentages in word problems. We will find the percents of quantities and will find a quantity, given the portion that is a percent. All of these problems are related and we use them in every day situations. Ask your student to help you when you encounter percents in life (at the store or at home). Here is a good video to help students determine how to find a percent.

7th Grade Math – Mrs. Evans

In math this week, our 7th graders will continue to learn how to write and solve equations. We are learning a process to solve equations that we are going to use on simple equations and then extend it to more complicated equations. This video shown below. Notice that each step is clearly shown and worked below the previous step. This helps us to be careful and avoid mistakes. Please encourage your student to develop a good PROCESS rather than focusing on finding the solution.

8th Grade Math – Mrs. Evans

We will continue our study of geometry in 8th grade math. We have been using known relationships between angles to find missing measures or to find variables involved with the missing variables. The first step in all of these problems is to determine what the relationships are between the sides and angles of figures. We must ask ourselves questions such as: Are the lines parallel or perpendicular or intersecting? Is there a transversal? Is the shape a triangle and if so, what kind of triangle? Are the angles vertical or corresponding, supplementary or complementary? Once we have thought through these questions we are ready to MAKE SENSE OF THE PROBLEM. It becomes like a little puzzle! This week we will extend these concept to coordinate systems. We will compare figures to determine if they are similar or congruent by comparing their corresponding angles and sides. Please have your student practice in IXL.COM if they are having a difficult time remembering these relationships. Practice will definitely help!

Algebra – Mrs. VonFeldt

This week began with the class solving absolute value equations. Absolute value is defined as a number’s distance from zero, hence, it is always a positive number. That means if |x| = 7, the solution is either +7 or -7. This is the first situation we have encountered where x has two solutions.

At the end of the week, we will solve two variable inequalities. Solutions will now be represented on a coordinate plane as a group of ordered pairs as is shown in the image below from mathwarehouse.com:
