• edit the headers of the table, which changes the titles on the graph
• color the data table to match the line colors

• identifying outlying data points, should they included or are they outlyers.

• selection of a point label it.
• select a range too
• showing the greatest slope requires 2 points

• select line, click some tool, (slope) = (deltaY)/(deltaX)
• ability to deal with real data with lots of noisy data points.
• turn this into

• setup a board with wax paper, wood and steel, block moving down the surface.
  • graph distance verus time for initial conditions
  • verbalize difference in the graphs.
    • describe the differences between two sets of data.

• have a selection tool, then describe about that range.

Stephen's

• questions to ask:
  • point to the spot, where block was going fastest?
    • graph can tell if that is right, or wrong.
  • how long did it take to get to the end of the slide.
    • have the student point to that spot on the graph to identify this.

• student picks a data set and runs a veritcal line across the graph and describe what is happening at that point
  • in the 2 data set case both lines are the same.

------

• if we can select a point or area
• then the graph tells the slope or value of the area

Ed's

• what is the value of the graph when the time is 2
• how long did it take to get from lenght 2 to lenght 10
  • answer is 5 sec.
  • if they are wrong flash it.

Coach with an activity:

• while the coach is describing the story the graph gets highlighted in different ways. As the coach says the student starts at the top, that part is highlighted.

Bargraph:

• plant growth
  • height each day different colors and labels
  • ask where is the growth the greatest.
• be able to show the comparsion between sequential bars.
  • highlight delta areas of the bars.

Flip back and forth between line and graph:

General form 1:

• ask them a question
• have them highlight the part of the graph
• give them guidance, using a verbal script, that can be filled in with information from the graph.

form 2:

• decribe a bar with words, using a verbal script with variables
  • the verbal script can change based on the conditions of the bar.

Large new idea is verbal scripts

• give the Author tools to write scripts that can be based on the

• add a button to the activity which programmically selects two points and then uses the functionally above to describe it.
