Asteroid Smash is an activity in JumpStart Study Helpers Math Booster. It is intended to teach spelling for 1st-5th graders.


Crabs are swimming around, each carrying a golden coin which they have stolen. Each coin is labeled with a letter. A word will be spoken, and will also be displayed at the bottom of the screen, but with between one and three letters missing (depending on the Game Play level). The user must shoot a bubble at each crab carrying a coin labeled with a letter needed to complete the word, which will encapsulate the crab in a bubble and cause it to drop its coin as it floats away grumpily. (If a crab carrying a coin labeled with an incorrect letter is shot, the bubble will instead encapsulate the coin and it will float away with the crab sticking out its tongue and still holding onto it.) The number of points which the user receives from each crab shot is also displayed, with the amount depending on how close to the "fourth wall" the crab is when it is shot. If it is shot while it is very far away, it will yield 150 points; if it is shot when it is very nearby, it will yield 75 points; in-between, it will yield 100 points. The user can also shoot other sea creatures for bonus points.


The user clicks to shoot.
