Help for Teachers
To create a new set of categories and problems:
•Update topics on title screen (slide 2)
•Rename category headers on question board (slide 3)
•Change category help slides (immediately following question board)
•Modify questions and answers (answers immediately follow each question slide)
•Cut and Paste Daily Doubles
Tips:
•Questions and answers are MathType objects. It is easier if you keep it that way.
Even for text problems.
•To put copy of question on the answer slide, copy and paste the MathType object from
the question slide then resize.
•The EXIT graphic on the game board will exit WITHOUT saving anything. It is
intended for student use when playing.
•Make sure you test your game to make sure everything is linked and working
correctly.
•When playing the intro screen of the game you can click in the lower right corner at
any time to skip the intro and go directly to the question board.
Do NOT:
•Change any hyperlinks
