## MS Math – March 20-24, 2023

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

We will continue our study of algebra this week, beginning with learning how to deal with fractions in equations. We can remember that a fraction is just another way to write any number. If we use our newly developed process, we can solve any equation. We can do anything to an equation as long as we do EXACTLY the same thing to both sides of the equation. We UNDO what has been done the variable by doing the inverse operation. We can check our solutions by plugging the solution in place of the variable and checking the math. We will extend what we have learned about equations to inequalities. The following are two videos that cover the basic solutions of all one step equations. Please have your student watch them if they are needing help.

In 7th math this week we will spend one more day practicing finding the surface area of prisms and then we will begin to find the volume of prisms. The following is a video about finding the volume of prisms:

This week we will begin to solve systems of equations using substitution. We will then review chapter 7 and have a chapter test. Here is an example of how to solve a system of equations:

Algebra – Mrs. VonFeldt

Last week, we learned to factor quadratic expressions with a leading coefficient of 1 (x^2 + bx + c). This week we will factor expressions with a leading coefficient that is not 1. The process we use is called “factoring by grouping”. The Khan Academy video below is a great demonstration on how to use this method:

Once a quadratic is factored, it can be solved using the Zero Product Property which states that if two or more factors have a product of zero, then at least one of those factors must be zero. Quadratic equations are useful in so many real world situations such as projectile motion, bouncing balls, free falling objects, and even architecture.

## MS Math – Week of March 6-10, 2023

No school on Friday!

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

We will be reviewing our lessons from Chapter 7 on Monday and do an assessment on Tuesday. With this chapter we have set a strong foundation to build on as we move into Chapter 8 and learn about equations. We have focused pretty heavily on vocabulary in Chapter 7 so to have the ability to discuss algebra most effectively. Here are some of the important vocabulary words that your student should master for success:

In 7th math this week we are investigating CIRCLES! On Friday of last week discovered the famous number, PI by dividing circle circumferences by their diameter. This week we will use formulas to find the circumference and area of circles. The following are the formulas that your student should memorize regarding circles:

8th Grade Math – Mrs. Evans

This week we are moving into algebra. We are simplifying and solving equations. We will also learn how to solve equations that have variables on both sides of the equation. An important concept to keep in mind for these problems is that you will keep the same value if you do EXACTLY the same thing to both sides of an equation. This is called keeping an equation balanced. Here is a video to help you:

Algebra – Mrs. VonFeldt

This week, we begin Chapter 8: Polynomials and Factoring. This week we will review how to combine like terms to create a simplified expression. Then students will explore binomial multiplication with algebra tiles and learn to multiply using the standard algorithm, sometimes remembered as FOIL:
