GEORGIA'S MATH PAGE!

Math is fun!

 

In math class we do all sorts of fun things from busy work to HUGE projects! Everything is fun! It's not normal math class. It's math class where we study pizza, super big hamburgers, calories, etc. and also we get marshmallows when Mrs. Reulbach makes a mistake! We all love math class!

Algebraic Expressions

 

Vocabulary Word	Definition	Example
Term	a number or variable	3g
Variable	a letter that represents a value	g
Constant	a number on its own	7
Coefficient	the number multiplied by the variable	3g
Algebraic Expression	an expression consisting of one or more variables	3g – 7 + 18g

 

 

Variables        Coefficients       Constants

(6g)(3k) + 4

 

 

When you simplify an algebraic expression you have to combine all of the constants together and all of the terms with the same variables together.

 4g – 6 + 8g

 4g + 8g = 12g

12g – 6

 

 

 

 

 

 

Georgia and Ally’s Population Project

 

Names: Ally, Georgia

 

Date: 9/17/13

 

Title: Population Project

 

Countries: Indonesia, and Fiji

 

Big Question: Why does Indonesia have a less amount of CO2 emitted per person than Fiji, when Indonesia has more people?

 

Hypothesis: Since more people die per hour in Indonesia, the amount of CO2 per person lowers and Fiji’s population growth doesn’t change.

 

Findings: The first thing we noticed was that Indonesia growth rate increases around 1860. We then noticed that the amount of CO2 decreases around age 65. We looked up Indonesia’s population and realized that 6.1% of Indonesia's population is 65 years or older.

                                    

                                                     

                                                                      Indonesia’s growth rate increases around 1860.

                          

 

Conclusions:

 

The reason that Indonesia has more people and a less amount of CO2 emitted per person is because there are so many people, it doesn’t matter how much they emit per person to emit more than Fiji. They already have a larger amount of CO2  because of their large population.

Reflection:

 

What I liked about this project: We really liked figuring out that the CO2 decreases as you get older, because thats when we figured everything out. We also liked this because we wouldn't  have chosen this topic to study in the first place, but it turned out being really cool.

 

What I would improve about this project: We would like to do this maybe with more countries.

EIGHTEEN SUPER SMART SPANISH SPEAKING SNAILS

 

by: Georgia Kratt

 

 Once there were eighteen super smart snails. Oh yeah, and they speak Spanish so that makes them super smart Spanish speaking snails! But, there was only one Spanish speaking snail that knew how to do scientific notation, her name was... Señora Snail!

 

She was the smartest there was in the snail kingdom, her best friend was Consnailo who loved to show his skill in ALGEBRAIC EXPRESSIONS and ALGEBRAIC EQUATIONS, that was his specialty. Moving on, the next snail is Pablo and he is Senór Snail’s husband and his specialties are distributive properties and variables. Pablo and Señora Snail only have two children and they are Paola and Alejandro. Paola loves to simplify fractions and Alejandro’s favorite thing to do are exponents! Alberto is Consnailo’s neighbor and he has one child and her name is Reina and she specializes in creating math problems for Paola, her best friend, that have very hard exponent problems with lots and lots and lots and lots and lots and lots and lots and lots and lots and lots of bases with huge amounts and to the x power (x = very big number). Tonio is the professor at the school of snails and he teaches some of the smartest and hungriest kids at the school, Sergio, Santos, Berta, Landrada, Paz, Beatriz, Silvario, Rodrigo, Rico, and Flavio! All of these super smart Spanish speaking snails master in expanded form which is taught by Tonio! These are the smartest snails in history of smart snails!

 

 

 

 

 

 

 

 

 

Rates and Ratios

 

By Georgia Kratt

Ratio-
A comparison between two quantities.
The ratio between blue stars and green circles is 6 to 4 because there are 6 blue stars and 4 greens circles. This is also written as 6:4 or 6/4. You can simplify this to get 3 to 2, 3:2, or 3/2 as an equivalent ratio.

Rates-
A comparison between two quantities where the units are the same.

Twelve 5 ounce bags of Trolli Sour Brite Crawlers for $13.87. You make this into a fraction: $13.87/1 divided by 5 = $2.77/1. You have to divide by 5 so you can get the unit rate.                                                   

 

Unit Rate-
A rate whose denominator is 1 when it is written as a fraction. The unit rate is $2.77/1 and that means that each 5 ounce bag is $2.77/1.                                                                                                            
              

The Difference-
The difference between the rate and ratio is that the ratio compares two quantities with the same units and the rate compares two different units. The ratio has three different ways of writing it. The rate involves more math than the ratio does.
