About This Chapter
Mathematical Representations - Chapter Summary
Work through the engaging lessons in this chapter to study mathematical representations. The chapter begins by helping you review types of mathematical models. You'll then get practice interpreting different types of graphs and explore methods that will help you better express mathematical ideas. The chapter also covers the real-world applications of graphs and tables, as well as strategies to help you restate word problems. After completing the lessons in this chapter, you should be able to:
- Identify types of mathematical models
- Read and interpret line and bar graphs
- Communicate mathematical ideas
- Restate word problems using works or images
- Use tables and graphs in the real world
This collection of mathematical representation lessons offers a straightforward and efficient way to review and practice these concepts. Our expert math instructors design each lesson to be fun and concise, which simplifies the studying process and makes it more memorable. You'll find highlighted definitions of key terms and formulas. You can practice applying these lesson concepts by taking the accompanying self-assessment quizzes. Word-for-word lesson transcripts are available to print and you can ask our instructors questions if anything needs clarification. To help you study whenever it's convenient, we've made these lessons available at any time and accessible on any desktop, laptop, smartphone, or tablet.
1. Types of Mathematical Models
Mathematical models can be used to represent just about everything in the real world. This lesson will explain what mathematical models are, in addition to describing and providing examples of the various types of models.
2. Reading and Interpreting Line Graphs
Watch this video lesson to find out how useful line graphs can be and how much information you can gain just from looking at one. Learn how you can apply that information in your own life to help you make better decisions.
3. Reading & Interpreting Bar Graphs
In this lesson, you will learn about the parts of a bar graph and what they mean. You will look at the title, labels, and bars of data, and then you can practice reading and interpreting a sample bar graph.
4. Restating Word Problems Using Words or Images
Watch this video lesson to learn how you can use sketches and notes to help you visualize a problem. Watch how easy it becomes to solve your problem once you have visualized it.
5. Using Tables and Graphs in the Real World
We use tables and graphs in algebra as ways to visually show an equation or function. But do we really use these in the real world? Is it that important to learn about tables and graphs? Find out in this video lesson.
