Goals/ Objectives/ Outcomes:
 

• Students understand the concept of Mean, Median, & Mode, through application.
• Students practice data collecting and management.
• Students learn how to work in groups.

• Significant digits.

• Data distribution (example-histigrams)
• Matrices.
• Interpreting data.
• Predictions with data.
• Defining data spread.

• Overheads
• Photo copies
• Long blank paper (for data calculations).
• Meter sticks (one per group).
• Overhead markers.

• Photocopies and overheads made.
• Get overhead markers.
• Get meter sticks.

• Review significant digits.
• Hand out notes on Mean, Median, Mode.  Quickly explain that the notes will be used for calculations later in the lesson.
• Hand out the Investigative Assignment and go through the instructions.
• Get students into groups of four.
• Give groups 10 minutes to collect, and pass in their height data.
• As the data is being passed in, record the data onto the over head of Table One.
• When table one contains all the student's data, display the overhead so that each student can transfer this data to their own tables, passed out earlier.
• Repeat this process for collecting data on the length of the hand.
• Then each student will be asked to answer question seven, of the investigative assignment, and place the formulated data in Table one and Table Two.
• While the students are calculating their data, calculate the answers, and transfer data to a overhead. Put up the overhead so that the students can check their answers.
• Make sure students place their completed tables in their portfolios for future use.

• Design group assessment rubric.
• Future journal writing pertaining to self evaluation of group work and understanding of the concepts.
• Always pause for questions to help determine if the students understand.

• Tell students future use of data,as pertaining to future lessons.

• To be determined during class.
