What's Your Coordinate?

0 Comments


In math this week we are moving on to geometry. To be more specific, we are learning about the parts of a COORDINATE PLANE.



First things first. Let's start with the vocabulary words. What is a coordinate plane, anyway?




Other important parts of the coordinate plane are...






In geometry, a coordinate plane includes all numbers, both positive and negative. It is divided into 4 QUADRANTS. We write the quadrants as roman numerals and the order travels around the coordinate plane in a counter-clockwise fashion.




In your math future you will plot points on all of the quadrants, so pay close attention to the coordinates. Are they positive or negative?




Before we move on, let's review what we've learned so far!




Today, we will stick with QUADRANT I where the x and y axes are positive (+,+).

When you use coordinates to plot points, you always travel across the x axis first. Then, move up the y axis. Across, then up.



This trick may help you remember what to do...

RUN across and then JUMP up!

 Thanks Mario!


Let's practice. Are the answers on this activity correct?



Now we'll do the plotting. On this activity, we were given coordinates. Are the points in the correct places? 


I believe they are! Nice work!


No lesson would be complete without a song. Am I right? Here's a catchy tune about the parts of a coordinate plane. Turn up your speakers and feel free to sing along!



 Yoooou ain't nothin' but a coordinate plane...

Thanks Mr. Phillips!

Let's Write Expressions!

0 Comments


In math last week, we learned about the Order of Operations.

Here's a refresher course...
 


Now that we know how to solve algebraic equations, we are going to learn how to write them! First up, let's talk about three important vocabulary words we'll need to know: mathematical symbols, expression and equation.




Let's learn how to write and interpret numeric expressions, shall we? Since they are expressions, we will not actually solve them.



 


 Here is a video that explains what we learned in class: 




I used the Grip and Rip technique to add notebook pages this week. I glued them in sideways and they look like this (image below). Groovy! You can click on the image to enlarge it. Please make sure your notebook is up to date by checking your k-mails and looking at past math posts.



If you were not able to complete the Quick Check in class, please send me the answers by Friday!



One more thing.

In class today, we were wondering how to type a division symbol. Here's how!

Windows/PC: 
Hold down the ALT key and type 0247 on the keyboard.
ALT + 0247

Mac
Hold down the Option key and press / (backslash)
Option + /


Thanks!

February Quick Writes!

1 Comments


With President's Day and our busy schedule, we finally got to our Quick Writes this week!

First, here is our February Brainstorm to get the creative juices flowing...

Here are our prompts for this month.
Remember, you only get 3 minutes to write!

She carefully opened the heart-shaped box, when suddenly…


 
General Washington turned toward his men and shouted…




The groundhog woke from a sound sleep when something…


Our post wouldn't be complete without a couple of student samples!



She carefully opened the heart-shaped box, when suddenly…  a genie popped out in cloud of pink dust and said in a thundering voice “Greetings you who is master of the box, I give you 3 wishes, and the kibosh on even more.” Elizabeth was quite surprised to see a mystical genie, then she regained her voice and said in a timid tone “r-really, you are a genie?” “Yes, I am,” replied the mountainous genie…                         By Cian


She carefully opened the heart-shaped box, when suddenly… a fake snake jumped out at her. RICKY! She knew it was him. he had done so many April fool tricks on her, he had put goo on her apple, he had put a rubber band on the sprayer on the sink so it sprayed her, he had drew a mustache on her last night, he had put toothpaste on her cookie sandwich, and she had had enough of it. She decided to do something back at him. She put red food coloring in his milk so he thought blood was in it, she put fake puke on his sandwich, and then he declared war on pranks. She got her friends together and told them all about. Her friends,The Pranksters, they now called themselves got very even with Ricky and he never bothered them again.                                   By Darla

Nice job Cian and Darla!

Order of Operations

0 Comments

This week in math we're learning about the Order of Operations.

Numbers 
and Operations
in a Formation...

Watch this video and you'll see what I mean!


Do NOT blame me if that song is stuck in your head until 2023.



Many things in math are not up for interpretation. We need to agree on certain math rules in order for  for humans to calculate numbers and communicate accurately.

For example, if you are ordering new carpet and the guy at Carl's Carpet Center asks you what the square footage of your bedroom is, you should both have an understanding of area. If you calculate differently, you may end up with too much or not enough lime green wool shag. (I had lime green shag carpet in my bedroom when I was your age, so don't laugh.)

"The Order of Operations is very important when simplifying expressions and equations. The Order of Operations is a standard that defines the order in which you should simplify different operations such as addition, subtraction, multiplication and division. 

This standard is critical to simplifying and solving different algebra problems. Without it, two different people may interpret an equation or expression in different ways and come up with different answers. The Order of Operations is shown below." (algebrahelp.com)



What's the difference between parentheses and brackets?

Sometimes parentheses are called "round brackets" because of their shape.

Square brackets remind me of staples that hold the numbers together.
