MS Math Week of Sept 13-17

We are looking forward to ZOOM Curriculum Night on Wednesday at 6:30 pm!

6th Grade Math – Mrs. Evans

This week we will be learning about prime factorization, finding the least common multiple and the greatest common factor.  These are foundational skills which will serve us well as we build new concepts to help us solve problems.  Our math books should be here soon, but for those who need a little extra help here is a support video on each of those important concepts: 




7th Grade Math – Mrs. Evans and Mrs. VonFeldt

This week we will continue to develop our ability to work with negative numbers and by the end of the week we will be able to add and subtract any integer.  The use of number lines and counters (in our mental space) can really help solve problems like these.  It is good to be reminded that SUBTRACTION IS THE OPPOSITE OF ADDITION.  This means that subtraction is just adding the opposite (negative) and subtracting a negative number is the same as adding that number.  For example:   

6 – 9 = 6 + (-9)        

9 + (-2)  = 9 – 2

7 – (-3) = 7 + 3   

For those who would like a little video support on this topic, here is a link to a great video:

8th Grade Math – Mrs. Ernest

This week we will review techniques from last week to identify least and greatest common multiples (see 6th grade math post above for some reminder videos on these topics). We will advance our understanding of multiplying and dividing fractions (Chapter 1 Lesson 2). 

Ex: How do I multiply a mixed number by an integer?

To multiply a mixed number by an integer there are two efficient strategies. The first is by looking at the calculation as repeated addition.

For example: 2 1/3 x 3 = 2 1/3 + 2 1/3 + 2 1/3

You then add the whole separately and then the parts and then combine to get the final answer.

2 x 3 = 6.

1/3 x 3 = 3/3 = 1

6 + 1 = 7

The second involves converting the mixed number to an improper fraction.

2 1/3 = 7/3

7/3 x 3 = 21/3 = 7

Multiplying Fractions Review:

Algebra – Mrs. VonFeldt

This week, we will focus on translating verbal phrases and situations into equations and inequalities. This is a very important skill to develop in order to become a proficient problem solver. Key words can be used to identify the intended operation, such as “more than” for addition, “difference of” for subtraction, or “shared between” for division. It can also be helpful to draw a diagram to represent what you are trying to find. Variables can represent any quantities that are unknown.

We will also use dimensional analysis to convert units and rates. Here is a helpful video that shows how to use dimensional analysis to for unit conversion and problem solving:
