Awareness Day 2011

Down the halls.  In the classrooms.  Everywhere it's buzzing with the talk of colors.  Colors you say?  Yeah, like, "I'm a blue, what are you?"  "Cool, you're a green, so am I!"


These are echoes of a time long ago where we were comparing ourselves as white or black.  However, the discussions and conversations taking place this week at RVMS had a different twist.  Students were looking at their different colors and seeing the strengths that each color had to offer.  In one math class, one team took a look at themselves and suddenly interrupted the discussion with, "Our team has one of each color.  No wonder we work so well together!"  Aahh.  What a novel idea.  To see our differences as strengths instead of as weaknesses.  What does the other person have to offer that I don't have?  How can I improve my own weaknesses to become a better person?


And then another question is raised.  "Mrs. McCabe, what would  happen if a group is all one color, like orange?  How will they work together?"  Well, seeing that they are all alike, they're probably going to do things similarly.  So, in this case, each person is going to have to dig deep, find those other colors to help them through the situation.


What can we learn from a person different than us?  How can we overcome those differences to see the similarities?  After all, with True Colors we learned that we all have the four different colors.  We all have something in common.  The only difference is that some people are really good at problem solving, some are really good at organizing things, some can add some energy to the mix, and others make sure that everyone is getting along.  We need all these people, just like we need all the people that are different than us in other ways...academics, sports, music, cultures, skin colors, religion, beliefs.  The list could go on and on, but the point is, we can be better people by accepting our differences and learning from others.  Instead of letting differences build a wall between us, use it as a stepping stone to  learning about others, to becoming better educated about the world around us.   
                                                                                              (Written by Mrs. McCabe several years ago)


Students spent today participating in a variety of activities for our 11th Annual 8th Grade Awareness Day.

They signed the "Call Me On It" pledge located in the cafeteria.


They listened to Mr. Addis' CORE training lesson, in which he helped prepare the students to make a difference.

C - Care...caring about someone can change someone's life
O - Object...you must object to those things that aren't right
R - Respect...treat others how you would want to be treated and even better
E - Encourage...be nice to others and encourage them


Students worked together in teams to create a tinker toy structure...building on their strengths and weaknesses.



Before filling our bellies with a delicious lunch of grilled hot dogs, chips, veggies, fruit, and cookies, each student painted a brick for the Awareness Patio in the courtyard.  These pavers represent the unit's message using various symbols.

Real Numbers Meet the Real World

Last Monday, 2nd hour math class got to Skype with Mr. McBryant from Arkansas about his job as a Wireline Engineer and how he uses real numbers (and their subcategories) in his job everyday.

What a great way to see math in action in the world outside our classroom walls!

The Real Number System Represented in Real World Terms

How do you see the Real Number System?
It's a complex system for categorizing all the numbers that we work with.
Here is how one student sees the categories.

What is the Math Behind Multiplying & Dividing by Negative Integers?

A question was raised today in Algebra class after going over the rules of HOW to multiply and divide by negative numbers...

"WHY does that work mathematically?"

In class, we were able to figure out why a negative divided by a negative equals a positive.


Now...the next question.
WHY does a negative multiplied by a negative equals a positive?

A Math Discussion...

Today in math, a great math conversation was in the making as Mr. Archbold broke down the Real Number categories into easier to understand segments.

Mr. Archbold gave several references of the Real Number System in "un-mathy" examples.  Ask your student how the following items are related to the Real Number System.



Today the floor diagram looked like this.


Yesterday, it looked a little different.
The diagram was a little simpler.
Students moved through the diagram categorizing various numbers of the  Real Number System.




(Sorry for the blurry pictures!  Will have to check my camera!)

Sorting numbers into the correct categories can be tricky.
There are new vocabulary words to learn.
Plus, the categories overlap, so the sorting becomes even more tricky!

Some good questions to ask your student...

1)  What is an integer? (ans. Any positive or negative number)
2)  What is the most specific category for 2/3? (ans. Rational Numbers)
3)  How are natural and whole numbers the same? (ans. They both contain the numbers 1, 2, 3, 4, and so forth)
4)  How are irrational numbers different than rational numbers? (ans. Irrational numbers cannot be made into a fraction.  Irrational numbers are decimals that go on FOREVER and NEVER REPEAT any of the digits...there is no pattern.)

Good Enough to Eat!

The Real Number System...
who would have known it could be connected to a
delicious,
yummy,
juicy cheeseburger.
With ketchup on the side!

One RVMS student got creative and aligned the real number system to something we see everyday.
Way to go!

Introducing...Mr. Archbold


Dear Parents,



My name is Andrew Archbold and I will be completing my Clinical Teaching Experience in Mrs. McCabe's math classroom this year. I am originally from Colorado but have spent the majority of the last three years in Sterling, KS. Some of my hobbies include baseball, running, and hiking. I will be slowly working my way into the classroom and look forward to working with your child for the next eight weeks and learning from him/her as they learn from me.


Sincerely,
Mr. Archbold

Working It Out

It takes practice to understand the math concepts gone over each day.

An Average Ad

Students used the concept of central tendencies as their focal point when they created an ad to promote a product.  So many times when we hear the word "average price", we think they are talking about the mean, when the median and mode are actually averages as well.   Class discussion following each ad addressed this and we looked at which "average" should have been used in the ad.



Talking points with your student...
1)  What is the median of a set of data?  How do you find this?
2)  How do you find the mean?
3)  The mode refers to what part of the data?

Students will be able to show what they know on the quiz next week block day!
To help your student, click on "Math Notes" in the above tabs for some definitions and a helpful website!

Have a great Labor Day weekend!
