# MS MATH – JAN 30 – FEB 3, 2023

HAPPY CATHOLIC SCHOOLS WEEK!

THIS TUESDAY IS THE LAST WINTER SPORTS DAY FOR MIDDLE SCHOOLERS

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

We are in the heart of Chapter 6, learning about how to convert between different units. Last week we covered units of length, capacity and mass, using both the metric system and the customary system. Here is a great visual aid that can help you and your students make changes between metric system units. Because the metric system is a base ten system, converting between units is a simple as multiplying or dividing by a power of ten (moving the decimal to right or left).

7th Grade Math – Mrs. Evans

In math this week, our 7th graders will continue to write, model, solve and graph inequalities, extending into two step inequalities. Solving inequalities follows, basically, the same process as solving equations. There are two major differences: first the solution of an inequality is a set of numbers rather than a single number and second, when you are in the process of solving an inequality and you multiply or divide each side of the inequality by a NEGATIVE number, you must flip the inequality sign for it to remain true. Here is a video that can help students with inequalities:

8th Grade Math – Mrs. Evans

This week we will finish Chapter 5 with a fun project in which we will have to solve transformation problems in an escape room. In Chapter 6 we will take our study of geometry in a new direction with the review of circle geometry. We will use the diameter and radius of circles to find the circumference and area. Here are the basics of a circle we will cover this week.

Algebra – Mrs. VonFeldt

This week, we will practice solving linear systems of equations using graphing, substitution, elimination, and rewriting. By the end of the week, students will be able to identify the best method to use for any set of lines. We will focus on how to use these concepts in many types of real-world comparisons. The Khan Academy video below explains how to solve systems using the elimination method:
