Make up your own What's in the case problem
You order 14 lipstick
You get 2 case and 2 separate lipstick
Algebraic Way: 2c+2=14
You can find whats in the case by subtracting 2 from each side leaving
2c=12 Then you can divide it to
C=6

Make up your own "What's in the Bank?" Problem and make a key that shows the steps to find teh correct solution.
Delta Bank has 20d 50s and $100, they had earned 2d 3s and $5 for their work on Tuesday later that afternoon someone deposited $220 into their banking account. On Wednesday they were robbed of 10d and 30s how much money do they have now?
First you add 20d+50s+100 to 2d+3s+5
You will get 22d+53s+105
Then you add the $105 to 220.
Now you have 22d+53s+325
After that you have to subtract 22d+53s+325 by 10d+30s
Finally you will have 12d+23s+325 as your final answer

Write and solve your own word problem that use signed decimals or fractions, Then tell the steps to solve the problem using the 4-step problem solving plan
Danh has positive 220 dollars in his bank.He Withdraws negative 50 dollars every day for one week straight.
How much money will Danh have after one week?
Total amount of money he withdraw in a week: 50x7= $350
This is the amount AFTER he withdraw money: 220-350=$-130
Steps to solve: You first have to find how much he had owed altogether which was 350.Then you had to subtract 250 by 350, but first you had to change the subtraction sign to a addition sign. After that you had to change positive 350 to negative 350. Then you add the numbers together and you will have -130 because the bigger number gets the sign when there are two different number signs.

Explain a situation where you might need to compare and order integers
There are several situations when you will need to compare and order integers. Firstly you will have to know what an integers is before comparing or ordering them.An integer is either a positive or negative number including zero. Positive integers are all the whole numbers greater than zero. Negative integers are all negative numbers less than zero.Now that you know what are positive and negative integers lets get to how we compare and order them then, what kind of situations we will have them in. Comparing and ordering integer is quite easy where is some examples. First i will use the positive ones. Comparing: 5<7 -7<-5 notice that 7 is a bigger number so the first example was right but the second one -5 was bigger becuase -7 is smaller than -5. Bascially we can call the negatives under sea level so -7 will be deeper than -5 so -5 would be bigger.Now comparing integers are easy you will just put them in order. Example: you have 5 numbers -6,3,0,-3,4 now to put them in order -6,-3,0,3,4.Now finally there are several situation where you might need this skill. Firstly when you are in math class.Secondly when you owe money and how much money you have.Lastly when you are trying to find the difference of the depht or height of 2 or more things. Keep in mind there are more situations when you need to compare and order integers!

How to make a accurate representation of what food FPMS like
Hello i am Danh Pham and i will tell you how i would make a survey of a lunch form to see people's favorite food at FPMS! First you won't want to waste a lot of time so you would only want to survey only 3 classes or so per grade so you can get a pretty understanding about what food they like. So after you survey the 3 classes you. You would also list the favorite food choices like lasenga,pizza,etc. Now you will have enough data so you will put on a sheet of paper now a class estimate in FPMS is 30 so you will estimate and multiply the number of classes there are in FPMS and that will give you a good estimate of how many people like what food and then you would put down on a sheet of paper what food they like and how many like them then you verify the information then put on a poster board or construction paper for everyone to see! Then that would be how you would make a accurate representation of what food and how much they like it.

Different Graphs
Hi my name is Danh Pham and i will be talking about the different types of graph and what is it useful for! The first i would like to talk about is the bar graph.It is a graph used to compare data. A line graph is a graph used track data through time so it would be great for how much money u gain per month. A circle graph is a graph that you can use for percentages.The histogram is useful when you have a lot of numbers and can be use to display easier. Venn diagram is useful for when you want to see the differences and whats alike. The last graph i would be talking about is the is the line plot which is used when you want to know the frequency data of a certain category.
