Lesson 11

For many of you, this week will be a wonderful break from solving equations because you like reading maps and graphs.  Most people have current experience reading maps in order to get to where they want to go.  Charts, diagrams and graphs are frequently found in the newspaper and on social media.  This week we will study reading maps and graphs, make tables in a spreadsheet, make graphs by hand and make graphs in a spreadsheet.  I hope you didn’t fall out of your chair with excitement!  The key to understanding graphs is to make sure you read all of the labels carefully so you know what it is really about.  Many graphs or charts in the media are intended to mislead you to jump to a particular conclusion.  However, if you carefully study the graph, you won’t be tricked.  Misleading GraphCheck out the graph to the right.  What was your first impression of the graph?



Here is an additional tutorial to watch to help you with basic graphing.  You will need basic graph paper for one problem from each assignment in this lesson:  Exercise 4.1 A, B & C.  You can download basic graph paper here.  (Basic Graph)  You will need coordinate graph paper for a group of problems on Exercise 4.1 A, B & C.  You can download coordinate graph paper here. (Coordinate Graphs)


If you need additional practice beyond what is in the textbook, print off the following worksheets & answer keys: Graph Ordered Pairs Extra Practice Worksheet and Graphing Data from a Table Extra Practice Worksheet.

Here is an additional tutorial to watch to help you with creating a graph in Excel.  You SHOULD watch this because it will walk you through how to do Exercise 4.1 Part B #11 and Part C #11.  By viewing this video and practicing along with the video, you will be able to easily do your Portfolio Project which is Exercise 4.1 Part C #21.
