19. Circle Graph – a way to show data using slices of a whole circle

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?

26. 6. How much more popular was Apple 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

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 Focus Skill This week’s focus skill is recognizing, reading, and solving problems using Circle graphs and pictographs.
