Spelling Mode
When the user enters the ÒSpelling Mode,Ó he or she is given a question like ÒWhich object contains a double ÔllÕ?Ó  There are six objects on the screen and it is up to the user to choose the one that satisfies the question.  In this example, if there was a ball on the screen, then that would be the correct answer; the word ÒballÓ has a double ÒllÓ.
