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. Check out the graph to the right. What was your first impression of the graph?
