  • 19. Circle Graph – a way to show data using slices of a whole circle
  • 20.
  • 21. Circle Graphs
    This week, we will recognize and correctly read a circle graph
    Circle Graphs Should Have:
    Title
    Key
    Labels
    Data Slices
  • 22. Draw the graph. Circle and label each part of the graph.
  • 23. 1. What is this graph showing us?
  • 24. 2. Which food is most popular?
    3. Which food is least popular?
  • 25. 4. What percent students liked Pecan Pie?
    5. What percent of students liked Cherry Pie?

    Pie than Coconut Cream Pie?
    7. What percent voted for Cherry Pie
    or Pumpkin Pie?
  • 27. 8. State two facts from the graph.
  • 28. Create a Circle Graph
    We will collect and graph class data in a circle graph.
    First, let’s collect data – raise your hand for your favorite type of food:
    Italian
    American
    Mexican
    Asian
  • 29. Create a Circle Graph
    Using this data, let’s design a circle graph
    Start with the title:
    Draw a circle where the graph will be drawn in.
    Now, cut the circle into pieces according to how many people voted for each food compared to the whole class (36 people).
  • 30. Create a Circle Graph
  • 31. Pictograph – a way to show data using a group of pictures
  • 32.
  • 33. Pictographs
    This week, we will recognize and correctly read a pictograph
    Every Pictograph Should Have:
    Title
    Labels
    *Key
    Data Pictures
  • 34. Draw the graph. Circle and label each part of the graph.
  • 35. 1. What is the graph telling us?
  • 36. 2. What sport was most popular?
    3. How many students voted for it?
  • 37. 4. What sport was least popular?
    5. How many students voted for it?
  • 38. 6. How many more students voted for soccer than football?
  • 39. 7. State two facts from the pictograph.
  • 40. 8. What does the key show?
    9. The store has the most of which kind?
  • 41. 10. How many Golden Delicious apples?
    11. How many Red Rome apples?
  • 42. Create a Pictograph
    We will collect and graph class data in a pictograph.
    First, let’s collect data – raise your hand for your favorite sport:
    Soccer
    Baseball
    Basketball
    Football
    Other/None
  • 43. Create a Pictograph
    Using this data, let’s design a pictograph
    Start with the title:
    Now write a key where each ball = 2 students
    Draw a box where the graph will be made. Label the left side with the sports.
    Now, draw a picture for each sport. Remember, you may need to use half a picture to represent numbers.
  • 44. Create a Pictograph
    KEY
  • 45. Graphs
    Online Practice
  • 46. Week 8
