Our Data and Graphs unit shows students how to read and interpret line, bar and circle graphs. Students are also shown how to construct these graphs from data in a table. They will then learn how to determine which graphs are appropriate for a given set of data. Try our sample lessons below, or browse?other units.

Data and Graphs |
Description |

Data and Line Graphs | Students are introduced to the parts of a line graph and the purpose of each. They are shown how to read and interpret data from a line graph. |

Constructing Line Graphs | Students are shown how to construct a line graph from a set of data. Step-by-step procedures are listed along with large, detailed graphs for visual reference. |

Data and Bar Graphs | Students are introduced to the parts of a bar graph and the purpose of each. They are then shown how to read and interpret data from horizontal and vertical graphs. |

Constructing Bar Graphs | Students are shown how to construct a bar graph from a set of data. Step-by-step procedures are listed along with large, detailed bar graphs. |

Data and Circle Graphs | Students are introduced to the parts of a circle graph and the purpose of each. They are shown how to read and interpret data from a circle graph. |

Constructing Circle Graphs | Students are shown how to construct a circle graph from a set of data. They are also shown how to compute the angle measure for each item in the circle graph. Step-by-step procedures are listed along with large, detailed graphs. |

Comparing Graphs | Students are presented with the purpose of each type of graph. They are then shown how to determine which graph is appropriate for displaying a given set of data. |
