 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.

 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.
