MS Math Feb 28-March 4, 2022

6th Grade Math – Mrs. Evans

This week we will finish Chapter 7 with a test on Tuesday or Wednesday.  We now have an excellent foundation to do some basic algebra.  Here is a video discussing many of the basic topics we have covered.  

After we finish the test, we will extend our algebra skills learning about equations and how to solve them.

The 7th grade has completed Module 8 and will test on the topics mid-week.  In this module we have learned about triangles, scale drawings and angle relationships.  We will move into Module 9, in which we will investigate circles.  For those wanting a little more help with the module 8 skills, please visit this area in KHAN ACADEMY:

8th Grade Math – Mrs. Ernest

The 8th graders will be revisiting graphing skills and working on Geometry concepts like Translating, Rotating, and Reflecting shapes mathematically! Students will review similar shapes as they work to graph and shift different polygons. As we move forward this week, students will be able to both describe the side lengths, angles, and types of transformations different shapes have gone through. On Friday, we will work on a tessellations project, inspired by the mathematical artwork of M.C. Escher!

Algebra – Mrs. VonFeldt

Students continue to practice simplifying exponential expressions using all the rules of exponents. This week we will explore exponential growth and exponential decay functions. Some very important real world problems can be studied or explained using exponential models. Examples include compounded interest, population growth or decline, radioactive decay, and depreciation. We will use the exponential growth model (shown below) to compare the difference between compounding interest monthly versus yearly. The Chapter 7 Test will be early next week.

The following video is a good summary of how to use exponential functions:

6th Grade Math – Mrs. Evans

This week we are continue working in Chapter 7.  Last week we learned about exponents and how to write and evaluate numeric expressions using the proper order of operations.   This order can be summed up with the numonic:  PEMDAS, which is shown below:

This week we will begin writing algebraic expression and learning how to evaluate those expressions for given values of the variables.  Then we will be learning to simplify expressions by combining like terms.  These skills will be the basis for algebraic studies.

Last week we began our study of geometry in Module 8.  We learned about scale drawings and will use proportions to solve for dimensions.  Proportions are useful in many areas of math.  We last encountered them when we were evaluating rates.  Proportions can in a number of ways, the most direct being CROSS MULTIPLICATION.  Here is a video that discusses solving proportions:

This week we will be making observations about triangles.  We will learn about the Triangle Inequality Theorem which summarizes how we can tell if 3 lines will create a triangle.  We will also learn about the angles of a triangle.  We will be using a great program called GEOGEBRA, which is a great place for investigation.  Here is a link to the program:

8th Grade Math – Mrs. Ernest

The 8th graders will be practicing their algebra skills as we solve for missing angles in triangles, complimentary and supplementary angle problems. Students will be able to identify like terms (terms with X or without X) and move numbers from one side of an equation to the other. We will have a quiz on these skills later in the week.

Algebra – Mrs. VonFeldt

We have finished our study of systems of equations and systems of inequalities. Students should be able to evaluate a system and determine the most effective method to solve. There will be a test on Chapter 6 on Wednesday.
