The students will make line, bar, double line, double bar, and circle graphs using information obtained from the Internet or by surveys. The students will use the computer to gather data, organize data and construct the graphs. They will also make interpretations of their data, find measures of central tendency and present the information to the class.

STANDARDS
List Standard # and Key Idea #: Write out related
Performance Indicator(s) or Benchmark(s)
MST Standard 1: Analysis, Inquiry, and Design-Scientific Inquiry
Students chart and graph data to make conclusions.
MST Standard 2: Information Systems
Students use the Internet to gather data and programs to graph their data.
MST Standard 3: Mathematics-Measurement
Students use measures of central tendency to display, describe, and compare data.
Students produce graphic representations of data using computers.
MST Standard 5: Technology-Computer Technology
Students use a computer to gather data from the Internet.
Students use a computer to construct graphs.
INITIATING ACTIVITY
1. Demonstrate to students how to use the Internet to collect data or set up a survey. Collect some data to be graphed.
2. Use a newspaper to show students how charts and graphs are used to explain data.
LEARNING EXPERIENCES
In
chronological order including acquisition experiences and
extending/refining
experiences for all stated declarative and procedural
knowledge.
Day One:
Teacher demonstration on logging onto the Internet/computer and searching for information.
Students brainstorm topics to search on the Internet.
Students practice this with supervision. They could also be provided a list of sites that could provide data to graph. (For example: US Census page and Yahooligans).
Day Two:
Students search on the Internet for web sites and data banks for gathering information to use in their graphs.
Students could also set up a survey on the computer for others to answer, as a way to gather information.
Day Three:
Teacher demonstrates how to chart (organize) data, and explains the different types of graphs.
Teacher explains each type of graph and why each is used. This is done using graphs from the Internet and the newspaper.
Students organize their data into a chart, and decide which graph will work best for their information.
Day Four:
Teacher explains the measures of central tendency (mean, median, mode, and range) and demonstrates how to solve each type.
Teacher explains when to use each type and which type is most appropriate for each set of data.
Students answer questions using the measures of central tendency, finding each, given sets of data.
Day Five:
Teacher demonstrates how to construct different graphs using the computer. This can be done with Microsoft Word or Works.
Day Six:
Students construct graphs using the computer, labeling all axes and titles. Teacher is facilitator.
Day Seven:
Students calculate the mean, median, mode, and range of their collected data.
Students compare their measures of central tendency and decide which measure best reflects what they want to be known from their data.
Day Eight:
Students work on their presentations. (They present their data, graphs, measures of central tendency and conclusions made about the data.)
*Additional days may be used based on need.
CULMINATING PERFORMANCE
Include
rubric(s)
Students present to the class the data, graphs, information and conclusions made about their data. This can be done with a PowerPoint presentation or with other computer graphs done on Microsoft Word or Works programs.
