## 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.

Starting Wednesday we will move into Chapter 7 in which we will be studying exponents, order of operations and expressions.

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

This week our class is finishing Module 7, with a test on Tuesday.    For those interested, the IXL practices that would be useful in practicing our new material are ONE VARIABLE INEQUALITIES, T1-T7.  For those who like to see our lessons demonstrated by Khan Academy, follow the link below.

On Wednesday we will begin to study scale drawings and how to use them to solve real world issues.

8th Grade Math – Mr. Pryor

The 8th grade math class moving into 6.3 and 6.4 this week. We are going to be able to find the volume and surface area of spheres and several other 3D shapes.

Algebra – Mrs. VonFeldt

This week the class continued to solve systems of equations. We looked at real world applications for these problems. The Chapter 6 test will be early next week.
