A Revolution in Education
Just found the answer to my own question... yes, the button for the TI-emulator has been removed from NB11 Math tools. There were too many conflicts when TI updated their software, I guess. :( Oh well, I can always just launch it independently - and all of the features still work seamlessly w/NB11 :)
BAK, How do you launch the TI emulator independently? Please explain!
I open NB, then launch the TI-84 emulator - it is a program separate from Notebook and a separate purchase from TI, but well worth it for high school math teachers! After launching the emulator, I choose 'keep on top' so that it is at the side of my notebook page where I can drag and drop graphs, windows, tables, etc. This is fabulous! I hear lots of ooohhhs and ahhhhhs when I demonstrate it to workshops with math teachers :)
