“Mathematics is the language in which God has written the universe.” ~Galileo Galilei
We will not have class on Tuesday as the students will have their last Winter Ride Day. Happy Catholic Schools’ Week!
6th Grade Math – Mrs. VonFeldt & Mrs. Creech
So far, we have been using ratios to represent a relationship between two or more quantities. In this next week, the 6th graders will begin to look at the percent ratio, or a comparison of a quantity to 100. Percent is everywhere we look: tax on purchases; items on sale; nutrition information; batting averages; even grades. Ask your student to point out when they see a percentage. This week, we will begin by converting basic ratios to percentage. We may even begin to calculate the percent of a number.
7th Grade Math – Mrs. VonFeldt
This week the 7th graders will be learning about angle relationships: supplementary, complementary, vertical, and adjacent. See the image above for a visual representation. Using these relationships, we will be writing algebraic equations to solve for missing values. The video “Math by Mr. J” shows some examples of how to use this process:
8th Grade Math – Mrs. Evans
This week, in 8th grade math, we will finish our work in Chapter 4 with the study of dilations (lesson 4.4). Then we will learn about angle relationships. We have studied many different angle relationships in 7th grade but after reviewing these, we will extend our studies to include transversals. This week, in that we will not have math on Tuesday due to Winter Sports day, we are only likely to review the angle relationships that we have seen in 7th grade. Here are those relationships:
Algebra – Mrs. VonFeldt
In Algebra, we will begin to look at systems of equations. We will discuss what a solution to a system is, how to find it, and what the solution can tell us about different situations. This week, we will solve systems graphically and using the substitution method.
