## Middle School Math as May Ends and June Begins! Happy Memorial Day!  As the year moves towards a finish, we are still busy learning new things, reviewing old and confirming our math skills!  Here are some things happening in our classes over the next few weeks:

6th Grade – Section A – Mrs. VonFeldt

We are looking at ways to evaluate data this week. We will focus on histograms and then learn to calculate measures of central tendency such as mean, median, and mode. Next week we will focus on reviewing all that we have learned this year in preparation (and celebration) for the final test on June 6 and 7. Now is a good time for students to check their Power School for missing assignments.

6th Grade – Section B – Mrs. Evans

We have just finished our study of geometry and will consider how to evaluate large groups of data by representing it in histograms, determining mean, mode and median of the data and considering how a piece of data can be an outlier and change the way we look at the whole set of data.  We will have a quiz on Friday and then we will review what we have learned this year.  It is always enjoyable to see how far we have come, almost without noticing!

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

Pre-algebra will finish up the study of Probability on Wednesday with a test.  The 8th graders will be gone on Thursday and Friday on retreat but we will begin to review all the things we have done this year in preparation for our end of the year test.  It is a great time for students to get a bigger picture of how their math skills have progressed!

8th Grade Math – Mr. Pryor

Eighth grade math is taking their final test, chapter 9, on correlations and calculating lines of best fit. We will be taking a placement test and working on a project after chapter 9 is finished up.

Algebra – Mrs. VonFeldt

Algebra is winding down for the year. The students are taking their final test this week and then the 8th graders will be on retreat Thursday and Friday. The seventh grade will be working on extended learning after graduation. It has been a wonderful year and I wish everyone the best in Geometry!

## Middle School Math Post – Week of May 13-17 6th Grade – Section A – Mrs. VonFeldt

This week we will finish Chapter 10. The students have used models to understand the basic area formulas for common polygons: specifically parallelograms, triangles, and trapezoids. We have used these formulas to find the area of other regular polygons and composite figures. In Chapter 11 we will continue our study of geometry with surface area and volume. Please see the link to the video below in Mrs. Evans’ post.

6th Grade – Section B – Mrs. Evans

This week our class will finish Chapter 10 in Go Math – enjoying finding polygon areas!    We have been using models to understand the basic formulas that we use to calculate area of parallelograms,triangles and regular polygons.  We will test on Chapter 10 on Tuesday and then continue our geometric studies beginning with the surface area of solid figures.  Below is a link to a Khan Academy which will help give a great perspective of solid figure (polyhedra) nets.  Please visit the video!

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

Pre-algebra returns from various trips – DC and Portland – to continue the study of probabilities.  All of our hat projects are due at the start of the week – these projects began with design of a hat for USE YOUR HEAD hat company, and then utilized statistical studies in order to set a price on the hats.  Finally we evaluated marketing data to be able to make conclusions about who to best market our hats to in order to have the greatest success.  We used proportional reasoning, dot and box plots and basic concepts like mean, mode and range in the process.  This project summarized all that we learned in our Statistics studies.

We move directly into the study of probability this week.  We will begin with experimental probability of simple events.  Statistics and probability are important studies – please visit this video to see a real life application in Lake Victoria.

8th Grade Math – Mr. Pryor

Eighth grade math studying scatter plots and deciphering correlations and lines of best fit.

Algebra – Mrs. VonFeldt

This week we will be working in Chapter 10 and will be discussing sampling methods and ways to analyze information. Students will learn to calculate mean absolute deviation and discuss what this can tell us about our data.

## Middle School Math Post – Week of April 22-26, 2019 Happy Earth Day!

6th Grade – Section A – Mrs. VonFeldt

This week we are continuing to write equations in two variables. We will look at how to graph these relationships on a coordinate plane and find solutions on the graph. This is a preview into the algebraic study of linear equations. There will be a Chapter 9 test on Friday.

6th Grade – Section B – Mrs. Evans

This week our section of 6th grade will continue working on Chapter 9 in which we will be extending our understanding of writing equations to writing equations with a dependent and independent variable, translating between equations and tables and graphs.  We will do problem solving using these tools to make conclusions.

IXL has excellent practice –TWO VARIABLE EQUATIONS – BB.1 through BB.10

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

Pre-algebra continue in our studies of statistics and probability!  This week, we are comparing data from multiple dot and box plots.  We are learning to make inferences (predictions) about the populations from the plots and also by using proportional reasoning.

For fun, here is another optical illusion reminding us that we have to be very cautious in determining whether we are biased or not.  What do you see in these pictures?  8th Grade Math – Mr. Pryor

Eighth grade math is almost halfway through chapter 8. We are graphing now in standard and slope-intercept form and looking at manipulations.

Algebra – Mrs. VonFeldt

Students continue to solve quadratic equations. They now have four strategies to use: Factoring, Graphing, Completing the Square, and the Quadratic Formula. At the end of the week we will expand our study to include solving systems of quadratic equations. The test will be next week.

## Middle School Math – Holy Week

Blessings on your Holy Week!

6th Grade – Section A – Mrs. VonFeldt

This week we will begin Chapter 9. In this chapter, we analyze relationships between two variables in an equation, where one variable is dependent on the other. Students will begin by creating input/output tables and looking for patterns in the data.

6th Grade – Section B – Mrs. Evans

This week the 6th grade will be spending most of the week at Camp Hamilton but they will also continue learning about algebra as they create equations with two variables – one dependent on the other.  These lessons are in Chapter 9.

For those having some difficulty with the distributive property – please visit this link:

Using the Distributive Property

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

Prealgebra has begun to study statistics and probability!  We are investigating how to create random samples of populations and how represent the data when shown in dot and box plots.  We are learning to make inferences (predictions) about the populations from the plots and also by using proportional reasoning.                                                                                                                                                           We are becoming aware of the bias we have that inhibits us from being able to make random selections.  For a fun example – look at the circles below – come to class with your guess – which of the orange circles are bigger or are they are the same size? 8th Grade Math – Mr. Pryor

Eighth grade math is well into chapter 8. We are studying how to graph slope-intercept equations, starting with finding slope (m).

Algebra – Mrs. VonFeldt

Which function is a pineapple pizza and which is a pizza pinapple? In Chapter 9 we are focusing on solving quadratic functions. This week we will look at how to determine a solution using a graph, using square roots, and finally using the quadratic formula. To review factoring, use the Khan Academy link below.

Khan Academy: Factoring by Grouping

## 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.

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.

## Middle School Math at the Close of February!

News ~ Middle School Math this Week!

6th Grade – Section A – Mrs. VonFeldt

This week we will continue Chapter 7. Students will write and evaluate numbers in exponential form. We will also review the order of operations using PEMDAS. These skills will be essential as we begin writing algebriac expressions. 6th Grade – Section B – Mrs. Evans

This week we are moving into Chapter 7.  We begin with exponents and reviewing how to do mathematical expressions in the proper order using PEMDAS.  We will begin writing algebraic expressions.  Remember that IXL is a great place to gain practice and build confidence.

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

We are excited to begin studying geometry this week.   Last Friday we measured our classroom and created rough sketches with the dimensions.  This week, we will be creating scale drawings of our classroom and extending what we learn to evaluate scaling objects up and down.  Scale drawings can show things smaller than the drawing or larger.  Please visit the link below to see the subject explained by Khan Academy:

Scale Drawings

The following link is to an excellent interactive practice site, also by Khan Academy.

Practice Creating Scale Drawings

After investigating scale drawings, we will move into drawing triangles, using protractors and visualizing what happens when a plane dissects a 3D figure!

8th Grade Math – Mr. Pryor

The 8th grade math class finishing our calculations of volume and surface area of spheres. This was chapter 6.4. We have class time to work on a year-long review before our test on Friday on chapter 6.

Algebra – Mrs. VonFeldt

This week we will begin Chapter 7 by simplifying exponential expressions using properties of exponents. At the end of the week the students will look at real world applications of exponential growth and decay.

## February Arrives with a Flourish of Snow Did you know snowflakes fall at a rate of 3.1 miles per hour?      A special branch of geometry, called fractal geometry helps us study the shapes of snowflakes.   There are 6 basic types of snowflake shapes – flat, column, stars, dendrites, lacy, needle and capped column snowflakes.   The temperature and humidity of the air determines what type of flake will form.  Cool!

6th Grade – Section A – Mrs. VonFeldt

Due to the snow the Chapter 6 Test was moved back to Thursday but I’m sure the kids much preferred snowmen to school! Next week we will begin Chapter 7 where we will look at order of operations and algebraic expressions.

6th Grade – Section B – Mrs. Evans

We will be finishing Chapter 6 this week with a test on Tuesday.   For those interested, the IXL practices that would be useful in practicing our new material are UNITS OF MEASUREMENT, T1-T10.  For those who like to see our lessons (example of conversions of volume measurements) demonstrated by Khan Academy, follow the link below.
