Hey guys, My name is Vivian and this is my math page! I love math because we couldn't live without it!! I love graphing it is fun to interpret data. What I love about math class is our teacher, Mrs. Reulbach, she makes math fun!! My favorite thing that we do in math class is play math games.

 

My animal story:

 

Superstar Snails

Vivian Moore

 

In Snailand there lives the mighty majestic 8 snails. The snails are extremely smart, especially in math. They all go to snail school where they learn about exponents, how to read, how to write, etc. In the base of Snail Square, there lives a king and a queen. The king’s name is King Superscript and the queen is named Queen LikeTerm. Everyone in Snailand loves math!!! In the base of town, there lays the world’s largest school, Snail high. “Okay” said Mrs. Snailia, “Today we are going to learn about the Expression (algebraic expression)”. “So you start off with your variables, the definition for that is: a letter that represents a value”. “You also have to have a constant; that is the number on its own”. “Both of those together make a term, a variable and a constant”. “The coefficients are the signs that go with the number; multiplication”. “That is the whole algebraic expression class”! The next day at snail high was indescribable! It all started when Ms. Snailia announced today’s lesson, which was: ScientificNotation!“Did you know class that there is a way to abbreviate numbers”?”It is called the Scientific Notation”. “For example lets take 342,000,000,000,000”. “However many numbers there are that aren’t zeros are the ones that are written out”. “You would put the decimal in front of the first number and then however many zeros there are is the number that you would put to the power of 10”. “So the whole equation would look like this: 342 x 10^12”. “That is the scientific notation”. Everyone continued on throughout high school then College and so on but they never ever forgot Mrs. Snailia’s important lessons!

 



Term: A number and a variable
Variable: A letter that represents a number
Constant: A number on its own, it never changes
Power:  Goes with an exponent, tells how many times the number is multiplied by itself.
Scientific Notation: An abbreviation for numbers
Coefficient: The number multiplied by a variable
Base: The number that is on the bottom of the exponent
Superscript:The top part of the exponent
Alegbraic Expression: The entire problem
Exponent: Repeated multiplication growth
Like Term: Same variable and same constant

 

 

My Awesome rates and ratios document

(-Pictures, sorry guys!)

 

Ratio’s

Ratio-Compares two quantities where the units are the same. ORDER MATTERS!!!!!!!!As you can see in the photo above these are all ratios. Lets take a look at the red and blue squares. There are four red ones and three blue ones. therefore the ratio is 4:3 or 4 to 3 or 4.          _          3

Rates:)

Rate- A ratio that compares two quantities measured in different units as you can see There are six adults and three cars. The rate would be written like this:6 adults_____3 carsYou divide by 3 and you have the Unit Rate. Which is two adults per every one car.Rates and Ratios are very different and similar. Ratios compare two things that are the SAME unit. Rates compare two different things. They both compare two things.

Car Project:

 

Total Price of Dream Car:                                                                                 Total Price of reasonable car:

My Population Project:

 

Name(s): Olivia and Vivian

Date: 9- 19- 2013

Title: Olivia and Vivian’s Awesomely Awesome Population Project

 

Countries:  Fiji, North Korea, and France.

Big Question: Why do some countries have sudden increases and decreases in their life expectancies

Hypothesis: We Think That Some countries have different living conditions and are wealthier than others, and they can afford more medicine.

 

Findings: We found that North Korea has a big decrease in their life expectancy in 1999. Fiji, however, has no curve for a while then in 1924 Fiji had a huge increase and keeps increasing until present day. France has very many increases and decreases in their life expectancy over the years.

 

This is Fiji’s Life expectancy, as you can tell in 1924 fiji increases and does not stop because they are becoming a more developed nation.


France has many increases and decreases during the years because of the french revolution, and their democracies changing. When they got closer to present day, their life expectancy began to rise without dropping.


North Korea Has an all-of-a-sudden decrease in 1999. This happened because of famine (extreme scarce of food)

AND/OR

Links to animated GapMinder Graphs

 

Conclusions: We concluded that since these 3 countries are in three very different places, have different history and a different economy, they have very different life expectancies. The french revolution must have caused a lot of deaths of  all ages, and then they must have slowly rebuild their economy. The famine in North Korea must have dropped the life expectancy until they began to get more food. Over the years Fiji became a more developed country so the life expectancy went up as their cities grew bigger and they gained a stronger and richer economy. We have concluded that the life expectancy is based on the economy, wealth, and cleanliness of the country.

Reflection:

What I liked about this project: We liked learning about the history of countries and the ups and downs of their life expectancies. Also we liked seeing which countries had life expectancies higher than others

What I would improve about this project: We would have liked to have a little bit more class time to work on this project.

 

 

Math Pictures:

 

   

 

 

Term - A number, variable, or variables and numbers multiplied together.

Variable - A symbol for a number.

Constant - A number that is on its own.

Coefficient - A number used to multiply a variable.

Algebraic Expression - 1 or more algebraic terms in a phrase.

 

2x + 7 = y

 

x and y = variables

2 = coefficient

7 = constant

 

To simplify, you combine like terms ( combine the variables and the constants). 

 

4x + 13 -x

 

To simplify, you subtract x from 4x and you get 3x then you get your simplified answer which is:

 

3x + 13 

 

 

Have it your way Menu Project

By: Vivian Moore

 

 

Person - Myself

Weight - 79 LBS

Activities - Bowling

     

 Menu - Chick-fil-a

  • 8 count chicken nuggets - 270 calories

  • fries - 400 calories

  • vanilla milkshake - 500 calories

Total # of calories:  1170

 My favorite activity is ice skating and it burns 0.053 calories per minute.  

To figure this out you would:

 

Step 1. Multiply 0.053 and 79 to get 4.187 (rounded to 4.2)

Step 2. Divide 1170 by 4.2 to get 279

Step 3. Convert 279 into hours and minutes

 

3. It would take 4 hours and 39 minutes to burn off the calories.

4. solve for a = activity, w = weight, x = calories per minute, and c = calories

 

a(w)  =x

           ------

              c    

 

   4. Summary - My results showed that it would take a long time to burn off chick-fil-a through ice-skating. It takes 4 hours and 39 minutes to burn off all the calories.  


   5. Reflection - I had lots of fun doing this project!!! It was very easy to understand. This really helped my understanding of algebraic expressions. I learned that it takes a really long time to burn off calories and I also learned more about 2 step equations.

How is that math related?
I can't read the animal story, it's too bright!
