## Welcome to Lesson 1

**Study Skill: Making Mistakes**

We can use something that Fibonacci wrote in his
Book of Squares to tell us how what type of attitude we should have toward the mistakes we will make as we progress through this course. As you will see, the mistakes you make in mathematics are part of the process of learning mathematics. Everyone who studies mathematics makes mistakes. |

**Written Assignment**

**1.**Read

**Section 1.1**in your textbook, and answer the four

*Getting Ready for Class*questions.

**2.**Here are two Mini Lectures for this first section of your textbook. You should not watch the Mini Lectures passively. If you are watching a Mini Lecture because you are stuck on a problem in your assignment, then use the navigation buttons on the viewing screen to fast-forward until you find a problem similar to the one you are stuck on. If you are watching a Mini Lecture before you start working the assigned problems, then pause the video and work each problems before watching the solution on the video. It is always better to attempt the problem yourself before you watch the video. Also, there is a correlation between students who pause or rewind videos and those students who do well in the course. If the viewing screen is too small for you to read, then click on the

*full screen*button on the bottom right of the screen.

**3.**Work all the problems on the

**Matched Problems Worksheet**for Section 1.1. This is your minimum assignment. If you have a limited amount of time for this assignment, doing these problems will guarantee that you have covered the most important problems in this section of the book.

**4.**Work Problems 1 - 87 odd in

**Problem Set 1.1**of your textbook.

**Electronic Assignment**

Here is your first Electronic Assignment. Remember, if you complete all these electronic assignments with an average of 75% or higher, you will receive a one-year All Access Pass to all the eBooks, videos, and worksheets on XYZ Textbooks.com.
Electronic Homework Issues Many of you will be taking college algebra at a school where electronic homework is part of the course. There are three possible problems that can occur with this type of homework:1. You have the correct answer, but the homework system will not accept it. 2. You have the wrong answer, but the homework system accepts it anyway. 3. You have no way of knowing if your written work has the correct form. |

The ten questions below form your first electronic assignment. If you complete all the electronic assignments for this course, and you average is 75% or higher, you will receive a one-year All-Access Pass to all of the eBooks and accompanying videos on XYZ Textbooks.

**Desmos Demo Popups:**Below are interactive graphs to help you get an intuitive idea of the relationship between numbers in an equation and the graph of the equation.

**Take-Five Enrichment: Squares and Odd Numbers in Words and Visually**

This
Take Five video reviews the relationship between the sequence of odd numbers and the sequence of squares and then gives two additional representations for the relationship; it gives the relationship in words, and then it gives a visual representation of the relationship. We do this to introduce the Rule of Four. |
