Middle School Math for Week of March 25 – 29

Spring Break is just around the corner!Watch for fractals in nature!

6th Grade – Section A – Mrs. VonFeldt  

We are continuing to solve algebraic equations using inverse operations. Another way to think about this is to UNDO whatever is being done to the variable. If a number is being added to a variable, you must subtract that number from both sides in order to isolate the variable. Use the link below to watch a video on solving equations using multiplication or division. There will be a test on Thursday of this week.

Math Antics: Solving Basic Algebraic Equations

6th Grade – Section B – Mrs. Evans  

We continue as we were working last week with the addition that we will have a test on Thursday or Friday. 

As we continue our study of algebraic expressions in Chapter 8, we will be modeling equations and then solving them algebraically.  We will begin with simple one step equations which are intuitive and then use what we learn to solve equations that are less obvious.  Solving equations is like keeping a big scale well balanced as we move objects onto and off of each side of the scale.  There are a few topics that students can review at Khan Academy to help them in their work this week.  

Why aren’t we using the multiplication sign?

 Using the Distributive Property

Pre Algebra (7th and 8th Grade) – Mrs. Evans   

We continue in the study of geometry as we calculate surface area of prisms and composite shapes and then move to calculating the volume of geometric solids.   We will test on this module on Friday.  

8th Grade Math – Mr. Pryor

Eighth grade math is working on multi-step, multi-term algebraic expressions. We will be done with section 7.3 this week and there will be a test after section 7.4.

Algebra – Mrs. VonFeldt   

There will be a Chapter 8 test on Thursday of this week. It will cover polynomials and factoring. We have learned to add, subtract, and multiply polynomials using different strategies. We have also covered factoring quadratics. A firm understanding of polynomials will be important when we graph and solve quadatic functions in Chapter 9. Use this link to view the Khan Academy video on factoring quadratics by grouping.

Middle School Math for the Week of March 18-22

6th Grade – Section A – Mrs. VonFeldt  

This week we continue to solve one-step algebraic equations with addition, subtraction, multiplication, and division. We have used tiles to model our steps and then learned how to show each step algebraically. The following video is a great review of how to solve multiplication and division problems.

 Using the Distributive Property

Pre Algebra (7th and 8th Grade) – Mrs. Evans   

We are in the process, in Module 9, of learning about the properties of circles, formulas for circumference and area.  We will then move to calculation the area of composite figures by breaking them down into shapes for which we know how to calculate the area. This is a fun application of math, allowing us to be creative and look at things in new ways.  We will also be looking at how to determine the surface area of prisms, cubes and composite solids.   For more instruction on one of these topics see the links to Khan Academy below: 

Area of Composite Shapes

8th Grade Math – Mr. Pryor

Eighth grade math is working on multi-step, multi-term algebraic expressions. We will be done with section 7.3 this week and there will be a test after section 7.4.

Algebra – Mrs. VonFeldt   

We continue to work with polynomials in Algebra. The students have learned to multiply binomials using FOIL. We are now reversing that process to factoring quadratics in order to solve equations. There will be a Chapter 8 test next week.

Middle School Math March 11-14

   Happy Pi Day!!!

6th Grade – Section A – Mrs. VonFeldt  

This week we continue to study algebraic expressions. We will complete Chapter 7 and have our test on Tuesday. In Chapter 8 we will use our understanding of algebraic expressions to begin solving algebraic equations. We will end the week with a celebration of Pi Day! π

6th Grade – Section B – Mrs. Evans   

This week we are continuing to learn about algebraic expressions as we finish Chapter 7 and move onto Chapter 8.  Due to the snow last week, and the late arrival, we shifted our test to Tuesday of this week.  After our test, we will begin to extend our understanding of algebraic expressions and equations.   Below is a link to Khan Academy for extra explanations and lessons.

Khan Academy Expressions and Variables for 6th Grade

Pre Algebra (7th and 8th Grade) – Mrs. Evans   

We will have our test on Tuesday as it was postponed due to our delayed start last week.   After our test we will continue in our study of geometry, in particular, calculating the perimeter and area of circles.  We will even be calculating the value for pi – which is great because Thursday is Pi Day!     

8th Grade Math – Mr. Pryor

The 8th grade math class exploring multiple-term equations and solving for the variable. These equations involve fractional terms which will require finding a least common denominator across the equation. We will be doing an activity this week involving multiple-term equations.

Algebra – Mrs. VonFeldt   

This week the students students are learning to multiply polynomials. We will begin by modeling binomial multiplication and move on to learning some algebraic short-cuts, inluding the FOIL method. Thursday of this week is Pi Day! Of course, we will have some fun with Pi (and pie too).

Middle School Math March 4th – 8th

March on to Mastering Math this Month!

6th Grade – Section A – Mrs. VonFeldt  

This week we continue to study algebraic expressions. We will learn how to use the distributive property and how to recognize equivalent expressions. To practice what they have learned, the students will create a pennant that deomonstrates the concepts of combining like terms and evaluating expressions. There will be a test on Chapter 7 on Friday. 

6th Grade – Section B – Mrs. Evans   

This week we are continuing to learn about algebraic expressions in Chapter 7.  We will learn how to combine like terms and how to tell when two expressions are equivalent.  It is a very important time for us to become solid in our use of the proper order of operations and exponents.  We will have a test on Chapter 7 on Friday.  Here is a link to extra practice in order of operations to help you do well with algebraic expressions:

Practice with Order of Operations  

Pre Algebra (7th and 8th Grade) – Mrs. Evans   

Please note that we are trying to become more familiar with the resources available to us to clarify our lessons and we are currently looking at Khan Academy – which is marvelous.  Please encourage your students to go to these links and listen to the short lesson.  

We continue to work in Module 8 this week and will have a test on it Friday.  We began looking at similar shapes and scale drawings.  Use the following link to have a look at Khan Academy’s lesson on scale drawings and have a little extra practice.

Scale Drawings

Practice Creating Scale Drawings

Next we have been looking at what we know about triangles and how to draw them given some information – the protractors have been coming in handy!  We are happy to know that the three interior angles of any triangle add up to 180 degrees!   We also learned about the triangle inequality rule that tells us about the allowed lengths of the sides of triangles.  Below is a link to Khan Academy to help you if you have further questions:

Triangle Inequality Theorem – Allowable Lengths of a Triangle

Very useful information!  This week we will be learning about relationships between angles – adjacent angles, vertical angles,  complementary and supplementary angles.  Here is a link to practice identifying angles.  This will be helpful to prepare for the test on Friday if you have questions.   

Angle Relationships

Take the opportunity to do mental gymnastics every day!

8th Grade Math – Mr. Pryor

The 8th grade math class starting chapter 7 on Monday. This chapter consists of combining like terms in algebra and practicing more complicated ways of solving multi-variable equations.

Algebra – Mrs. VonFeldt   

This week the students solved real-world problems that involved exponential growth and exponential decay. There will be a Chapter 7 test on Wednesday. In Chapter 8, we will be studying polynomials. This is the unit where algebra gets a little more challenging (and a little more fun!). We will begin by modeling polynomial multiplication using algebra tiles. It will be very important for students to keep up on their classwork and homework and ASK QUESTIONS when they need help.
