==Description==
The book takes place after the events of JumpStart Math for Second Graders. Ratso, still shrunken down to the size of a regular rat, decides to even the odds by casting a spell on CJ that shrinks him down too. Now CJ must figure out to restore himself to his normal size. Edison, who is bigger than CJ at this point, finds himself in a more active role, and plays a large part in helping CJ avoid dangers and discover how to undo the spell.
The book contains many activities. Each activity page depicts some kind of obstacle for CJ and Edison in the form of a problem that the reader must solve.
