  1. Interpret, read, and use information from tables and graphs. By Mr. Wilson By PresenterMedia.com

  2. Agenda 12:30am 12:33am 12:45pm Agenda, Set the stage for the rest of the period, What I want you to know (Charts & Graphs), How I will know you can do it (Assessments). Start Lesson Groups of two can stay together or quickly pair up with another group for groups of 4 Quick Follow Up & End of Lesson Pair off into groups of two and “Think-Pair-Share” 12:50pm 12:59pm

  3. Setting the stage • Raise your hand if you have any questions. • After a question is submitted, if you know the answer raise your hand and ask to explain the answer - HELP your classmates! • Get my attention if I am going to slow or too fast.

  4. What do I want you to know and be able to do? • This lesson will teach students how to: • Develop a chart, • Use charts to represent data, • Analyze data through calculations, and • Make future predictions from that data.

  5. Vocabulary Words • What is a Chart? • A chart is a visual representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart. • What is data? • Data is a collection of facts from which conclusions may be drawn.

  6. How will I know you can do it? • This lesson will teach you how to: • Explain the purpose of a pie graph, line graph, & bar graph, • Construct a bar graph in small groups, • Answer questions derived from graphs, and • Make analyses of graphs by predicting future outcomes.

  7. Would you believe me if I told you that I ran my own business? • I did... while I was in High School. • Look around… YOU ARE TOO! • I am proof that if you put your mind to something you can do it! • My friend and I ran a roofing installation business together. • A roof is the covering on the top of a building. It protects the building and its contents from the effects of weather.

  8. What does this have to do with this class? • To show our clients what we were putting into the project we would give them various graphs including: • A pie graph with cost of materials. (shingles, black paper, staples, nails, waterproof caulk) • A line graph showing the best time to buy materials throughout the year. • A bar graph to compare where it was cheaper to buy materials. (Lowes vs. Home Depot vs. local hardware store)

  9. What is a graph • A graph or chart is used to present facts in visual form. They are a drawing that displays the relative sizes of numerical quantities. • A graph is one of the easiest ways to compare numbers.   Graphs can be used to illustrate many types of data and are not limited to the simpler types such as line, bar, and circle. They should be used to make facts clearer and more understandable.

  10. Pie chart that shows cost of materials When multiplying a percentage you move the decimal point two spots to the left. $1200 x 61.22%(.6122) = $734.64

  11. Line chart showing when to buy materials What are the best months to buy materials?

  12. Bar graph showing where I should buy materials Where is the most cost effective place to buy materials according to the graph? Students – get with a partner and use Think-Pair-Share to explain the purpose of bar graphs. I will then ask a pair to explain when they would use a bar graph vs. a line graph.

  13. Bar graph showing where I should buy materials • Bar graphs are suitable when we want to compare quantities in different categories.Bar graphs use spaces between the bars to distinguish the categories. The heights of the bars across the vertical axis allow us to compare the value of the categories. • Example: The heights of the bars in the example below allow us to compare rainfall amounts, in centimeters, over 5 days in July, 2002.

  14. Grouped Bar Graphs • Here I have taken the same type of graph and added a second independent variable, years. • Now we can start making predictions…

  15. Group Work I want each group to add the rest of the data in the provided graph so that we can make sound predictions on how many hits these players will get. How do we predict how many hits he will get? How many hits do we predict each player will get this year?
