The game begins with the player signing up for the JumpStart Pen Pal Club. Mr. Brewster, the mail bird, will help the player sign in.
The game takes place at school during after the teacher has left for the day. The player meets CJ the Frog, an ardent, self-styled "adventurer", and his firefly friend, Edison, who is more of a pragmatic straight man. The two of them reveal a secret elevator behind a bookshelf that leads to several different floors.
Each floor contains at least one activity. Each activity has three difficulty levels: Scout (level 1), Explorer (level 2), and Trailblazer (level 3). Completing activities awards the player points. Points can be used to obtain post office stamps, which appear in the player's Stamp Book.
At the Mail Room, Mr. Brewster will often bring mail from JumpStart Pen Pals who need answering questions and solving problems. When the player decides to help a pen pal, they will be recommended to an activity that relates to the pen pal's query. Once the player has found the solution, they can send a letter back to the pen pal. However, the letter will require a stamp from the player's stamp book to be delivered.

- Strangely, the current cover art uses artwork of CJ from JumpStart Math for Second Graders plastered onto the 2000 cover art (with the background being gold instead of purple).
