Description
In this activity, various bugs with numbers on them roam around in a sixteen-unit grid. the player must use ice cubes with numbers 0 through 9 on them, and place them around the grid to freeze the bugs.

A math symbol is located at the upper left corner of the grid, which will display either a plus, minus, or multiplication sign. The player must place two ice cubes so that they form an equation that equals the number on the bug. For example, if the bug's number was 2, and a minus sign was displayed, the player could place a 5 on the left side of the grid, and a 3 on top of the grid, to make 5-3, which equals 2. For subtraction problems, the number that comes first in the equation must be placed on the left side of the grid, and the number which comes second must be placed on the top side of the grid.

When the bug reaches the spot where both ice cubes intersect, it will be frozen. If all of the spaces in the grid fill up with frozen bugs, a secret passage will be opened, which leads to the frozen remains of an ancient pirate ship.

At the pirate ship, the player can inspect the mariner's map to learn facts about the different continents. The mariner's map can also be used to complete pen pals' challenges.

Difficulty level differences

 * Scout - Addition and subtraction with numbers 0-9. Only one bug is present at a time.
 * Explorer - Addition and subtraction with numbers 0-9, multiplication with possible outcomes of 1, 4, 9, 16 or 25. Only one bug is present at a time.
 * Trailblazer - Addition and subtraction with numbers 0-9, multiplication with possible outcomes of 1, 4, 9, 16 or 25. Two bugs are present on the screen at once.

Digital manual description


Watch the creepy but friendly ice bugs skitter and scratch their way across the walls of the frozen cave. Place the correct numbers on the grid to create an equation which can be answered by the number on the bug. Creating a correct equation freezes one of the little critters. When the grid is filled, a secret passage opens to reveal an ancient Pirate Ship.


 * Click the Start button in the upper-left corner.
 * A Math symbol shown in the upper-left corner will show you which operation you need to perform to solve the equations.
 * See how the Start sign on the button changes to a new sign (+, -, X).
 * Click and drag the ice cubes with the right numbers to a place on each axis. When the bug scratches its way across to the intersection it freezes.

The Pirate's Ship The remains of an ancient pirate's ship are frozen beneath the Ice Cave. The mariner's map will help you solve Pen Pal challenges.

Click on any continent to solve your challenge and/or hear a fact about that continent.

Levels

1. Scout: The Scout adds and subtracts number 0 - 9, with the greatest possible answer being 18. The bug's number will repeat until a correct answer is given.

2. Explorer: In addition to the content in the Scout Level, the level introduces, multiplication with possible answers of 1, 4, 9, 16 or 25. The bug's number will repeat twice if an incorrect answer is given.

3. Trailblazer: The Trailblazer faces 2 bugs on the screen at the same time! Also, 2 possible answers are available.

Educational and Developmental Benefits
