Constructing Line Graphs

The student will be able to:

  • Define range, horizontal scale and vertical scale.
  • Examine the procedure for constructing a line graph from a given set of data.
  • Describe the procedure for constructing a line graph.
  • Construct line graphs for data presented in two exercises.

Data and Bar Graphs

The student will be able to:

  • Define bar graph, grid line and categories.
  • Identify the parts of a bar graph.
  • Examine bar graphs presented in examples.
  • Recognize that bar graphs can have vertical or horizontal scales.

Constructing Bar Graphs

The student will be able to:

  • Define bar, bar length and bar height.
  • Examine the procedure for constructing a bar graph from a given set of data.
  • Describe the procedure for constructing a bar graph.
  • Construct bar graphs for data presented in two exercises.

Data and Circle Graphs

The student will be able to:

  • Define circle graph, sector and pie chart.
  • Identify the parts of a circle graph.
  • Examine circle graphs presented in examples.
  • Recognize that a circle graph is easier to read when percents, not fractions, are used to label the data 
  • Explain why a circle graph is also called a pie chart.
  • Recognize, if there are more than five or six categories in a set of data, then a circle graph is not a good choice for displaying that data.
  • Recognize that circle graphs provide a visual presentation of the whole and its parts.
  • Interpret information from circle graphs presented in five interactive exercises.

Constructing Circle Graphs

The student will be able to:

  • Review the definition and purpose of a circle graphs.
  • Examine the procedure for constructing a circle graph from a given set of data presented in table.
  • Compute the values for the parts and the whole of the graph.
  • Compute exactly what fraction or percent each item (part) represents.
  • Compute the angle measure for each part of a circle graph.
  • Draw and label the parts of a circle graph.
  • Describe the procedure for constructing a circle graph.
  • Recognize that circle graphs represent data visually in the same proportion as the numerical data given in a table.
  • Construct circle graphs for data presented in two exercises.

Comparing Graphs

The student will be able to:

  • Define visual data display.
  • Describe the types of graphs learned in this unit and their uses.
  • Compare and contrast different graphs.
  • Recognize that circle graphs are best used to compare the parts of a whole.
  • Recognize that bar graphs are used to compare facts.
  • Recognize that a line graph is used to show changes over time.
  • Determine which type of graph is appropriate for representing a given set of data presented in five interactive exercises.

  • Interpret and analyze graphs presented to determine what information is given.
  • Compare a set of graphs that represent the same data in each of three exercises.
  • Determine which graph shows all of the facts correctly.
  • Determine which type of graph is appropriate for representing a given set of data in each of three exercises.
  • Determine what is wrong with graphs in each of four exercises.
  • Develop problem-solving skills.

Solutions

The student will be able to:

  • Examine the answer for each exercise presented in this unit.
  • Examine graphs presented as possible solutions..
  • Recognize that graphs created will vary depending on the scales used.
  • Compare possible solutions to completed exercises
  • Identify and evaluate incorrect answers.
  • Reconstruct and label graphs that did not accurately represent the data from completed exercises.
  • Identify areas of strength and weakness.
  • Decide which concepts and procedures need to be reviewed from this unit.
