## 数学代写|数学建模代写math modelling代考|Try it Out–PPW Story Representation 4, 5, and 6

In the below worksheets, first, you will use the bar model to represent the story. Then you will map the information into the PPW diagram equation. After you map the information into the diagram, you will check whether the sum of the two quantities from the left side of the equation IS THE SAME AS, or EQUAL to, the quantity from the right side of the equation. If NOT, you need to check the accuracy of your mapping against the story provided. Make sure you have, both, correctly entered the two parts into the two smaller boxes labelled part, and that you have correctly entered the total in the bigger box labelled whole on the other side of the equation. After correcting the mapping in the diagram, you will check again whether the sum of the two parts from the left side of the equation IS THE SAME AS, or EQUAL to, the quantity from the right side of the equation.

1. The pound had 67 dogs in cages waiting to be adopted. One week, 24 of the dogs were adopted. There were still 43 left at the pound.
2. A basketball player named Sarah scored 43 points in the first half of a game. Then she scored 12 more points in the second half. By the end of the game, she had scored 55 points.
3. Alex had 164 colored pencils. 57 of them were different shades of blue. There were 107 colored pencils which were not blue.One teacher had 23 flashcards for his students. Another teacher had 89 flashcards. In total, the two teachers had 112 flashcards.
4. One student’s mom baked 56 cookies for the class party. Her son and his friends ate 32 of the cookies before she woke up. There were only 24 cookies left for the party.
5. A cat caught 23 mice in the spring and summer. In the fall and winter, the same cat caught 53 mice. The cat caught a total of 76 mice that year.

## 数学代写|数学建模代写math modelling代考|SOLVING PPW PROBLEMS

Teacher: In the last Unit, we learned how to use the bar model and diagram equation to represent PPW problems. In this unit, we will use the bar model and the diagram equation to help us solve real world problems.
Problem $# 2-3-1$
Christie read two books over the summer. One book was 193 pages and the other book was 267 pages. How many pages did Christie read over the summer?
Teacher: what is this problem all about?
Students: The problem is about the two books Christie read over the summer.
Teacher: That’s right. What else does it tell us?
Students: One book is 193 pages, and the other book is 267 pages.
Teacher: Good. What are we asked to solve for?
Students: How many pages did Christie read over the summer?
Teacher: Great. Let’s underline the question in your worksheet. (Students underline the question in their worksheet; teacher does so on the board.)

## 数学代写|数学建模代写math modelling代考|COMPS PROGRAM

Teacher: Slide 2-3-1-a represents the story of problem 1. Slide 2-3-1-b represents the mathematical relation in the problem. To find out the answer to “How many pages did Christie read over the summer.” we can generate a math sentence based on the bar model. That is,
Total # of pages = the first short bar $+$ the 2 nd short bar, or
Total # of pages $=193+267=460$.
However, if we use the PPW diagram equation, the math sentence (or equation) for solving the problem is given by the diagram equation. That is, if we peel off the boxes from the diagram equation, we get
$$\begin{gathered} 193+267=? \ \text { Or ? }=193+267=460 \end{gathered}$$
What is a complete answer to this problem?
Students: The answer is: Christie read a total of 460 pages over the summer.
Teacher: Super!
The reason we use both the bar model and the diagram equation is that the bar model helps us to understand the meaning of the problem, as well as the meaning of the diagram. Later in the program, we will not have to draw the bar models. Instead, we can directly use the PPW diagram equation to represent and solve problems, as the diagram equation provides us with a defined math sentence, or equation, for our solution.

Let’s look at one more problem and represent it with both a bar model and the diagram equation. After that, we will only use the PPW diagram equation to represent and solve the problem.
Problem #2-3-2
The Girl Scouts were selling cookies at the mall. They brought 93 boxes of cookies with them, and they sold 47 boxes that day. How many boxes of cookies will the Girl Scouts have to take back home?
Teacher: What is this problem all about?
Students: The problem is about the Girl Scouts selling cookies. They have a total of 93 boxes of cookies, they sold 47 boxes.

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
