[Pibe-division] graphing

[Greg Aikens]

A screen board is also a useful tool for sketching tactile graphs on the fly.  The one I use is a piece of window screen that covers one side of a clipboard.  When you put the paper on the screen and draw on it with crayons, the rough surface of the window screen makes the crayons leave raised lines.  These graphs are fairly crude but can be made quickly.  They are especially useful for looking at the overall shape of graphs and introducing overall concepts.  I used one last spring to make it through a research class in graduate school but have been using one since 8th grade math.

Go to fabric store and pick up stick backed material, dots and other sticky back items that are great for making graphs into 3-D.  I also use the draftsman and students can draw their own pictures--Aph also offers a tactile kit which is wonderful too. Using a long slate n stylus so they can label the paper works perfectly.

We are having trouble reading the graphs in the book and understanding where the area between the lines are.  I would appreciate any help.
