Elevator

The elevator is a location in JumpStart 2nd Grade where CJ and Edison are inside. There are nine floors to choose from. The pen pals use a secret for CJ and Edison to go to. The envelope has a question mark on it to solve the challenge.

Clubhouse
The clubhouse is apparently C.J. and Edison's headquarters and is located directly above the classroom. Activities include:
 * The jukebox – Players insert different coins and bills of U.S. currency into the jukebox to hear music.
 * A computer – A simple computer used to type. It is not required to win the game.
 * A tree branch – A tree branch leads to a game of Concentration in the fruit tree outside. (The kind of fruit the tree has changes from game to game. The exterior shot of the school from the beginning of the program shows apples, but the view of the tree from inside the clubhouse shows oranges.)
 * The lookout – The user uses a clue to determine which planet in the Solar System is being "invaded" by malevolent robotic aliens. After the user selects the correct planet, C.J. and Edison fly there in a rocket and the user then has to play an arcade-styled game to save the planet which includes Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, or Pluto. (The aliens never invade Earth.)
 * The fish tank – The user must find which numbers and words fit into a specific category.
 * A post office has stamps to win 100 points.

Classroom
The classroom includes:
 * a painting activity (paint set) that includes two famous paintings to fill in as well as a sticker book to create a scene;
 * a bookshelf that consists of three grammar books in which either nouns, verbs, or adjectives are missing and need to be replaced;
 * a blackboard that presents three grammar songs which define nouns, verbs and adjectives.

Boiler Room
The game in the boiler room involves recycling several items. Aside from encouraging recycling and perhaps improving hand–eye coordination, this game does not appear to have any obvious educational value.

Football Field
On a football field, the user uses addition to figure out how many yards the players of the JumpStart team advance on the field and use subtraction to save the JumpStart team from penalties.

Bone Vault
Here, the user solves math and spelling problems to open the mysterious Bone Vault, which, predictably, turns out to be filled with bones. Inside the vault are various objects the user can measure with, by means of a scale and a ruler.

Cave Writings
In this activity, players decode meaningless messages written in American Sign Language, Braille and "Larvaic" ("language of the larva") using a key. Before the game can be played, however, the user must get past a giant Blues-playing caterpillar by answering a biology question.

Cricket Band
In this game, the user creates music with a band of crickets who jump up and down on piano keys.

Log Ride
The user solves math or spelling problems to help five gophers make it across a subterranean river so they can guide C.J. and Edison through their tunnels. After the game is completed, C.J. and Edison are taken to a cave filled with traffic signs. There, C.J. and Edison explain the meaning of whichever signs the user clicks on.

Ice Cave
The user answers addition, subtraction, and multiplication problems to freeze ice bugs so that they will fill a sixteen unit grid. After the user completes the grid, the ice floor breaks which leads to an old pirate ship that is frozen in the ice. There the user will find a map with all seven continents on it. When clicking on a continent, C.J. will inform the user about an interesting fact regarding it. Also, on a pen pal challenge, the user has to pick the correct continent to complete the challenge.

Inside the Elevator
The user can choose a floor by clicking. CJ and Edison are in the elevator. CJ or Edison says the floor they go to.
