math arithmetic gnumch-factors

 Manuel Tondeur & Timothée Giet

Description: Guide the Number Muncher to all the factors of the number at the bottom of the screen.

Goal: Learn about multiples and factors.

Manual: The factors of a number are all the numbers that divide that number evenly. For example, the factors of 6 are 1, 2, 3 and 6. 4 is not a factor of 6 because 6 cannot be divided into 4 equal pieces. If one number is a multiple of a second number, then the second number is a factor of the first number. You can think of multiples as families, and factors are the people in those families. So 1, 2, 3 and 6 all fit into the 6 family, but 4 belongs to another family.

Gnumch multiples
screenshot gnumch-multiples icon gnumch-multiples difficulty level 3

math arithmetic gnumch-multiples

 Manuel Tondeur & Timothée Giet

Description: Guide the Number Muncher to all the multiples of the number at the bottom of the screen.

Goal: Learn about multiples and factors.

Manual: The multiples of a number are all the numbers that are equal to the original number times another number. For example, 24, 36, 48 and 60 are all multiples of 12. 25 is not a multiple of 12 because there isn't any number that can be multiplied by 12 to get 25. If one number is a factor of a second number, then the second number is a multiple of the first number. You can think of multiples as families, and factors are the people who belong to those families. The factor 5, has parents 10, grandparents 15, great-grandparents 20, great-great-grandparents 25, and every extra step of 5 is another great- in front! But the number 5 does not belong to the 8 or 23 families. You can't fit any number of 5s into 8 or 23 with nothing left over. So 8 isn't a multiple of 5, nor is 23. Only 5, 10, 15, 20, 25 ... are multiples (or families or steps) of 5.

If you have a keyboard you can use the arrow keys to move and press space to swallow the numbers. With a mouse you can click on the block next to your position to move and click again to swallow the numbers.

Gnumch primes
screenshot gnumch-primes icon gnumch-primes difficulty level 6

math arithmetic gnumch-primes

 Manuel Tondeur & Timothée Giet

Description: Guide the Number Muncher to all the prime numbers.

Goal: Learn about prime numbers.

Manual: Prime numbers are numbers that are only divisible by themselves and 1. For example, 3 is a prime number, but 4 isn't (because 4 is divisible by 2). You can think of prime numbers as very small families: they only ever have two people in them! Only themselves and 1. You can't fit any other numbers into them with nothing left over. 5 is one of these lonely numbers (only 5 × 1 = 5), but you can see that 6 has 2 and 3 in its family as well (6 × 1 = 6, 2 × 3 = 6). So 6 is not a prime number.

If you have a keyboard you can use the arrow keys to move and press space to swallow the numbers. With a mouse you can click on the block next to your position to move and click again to swallow the numbers. With a touch screen you can do like with a mouse or swipe anywhere in the direction you want to move and tap to swallow the numbers.

Description: Pilot the spaceship towards the green landing area.

Goal: Understand the acceleration caused by the gravity.

Manual: The acceleration caused by the gravity experienced by the spaceship is directly proportional to the mass of the planet and inversely proportional to the square of the distance from the center of the planet. Thus, with every planet the acceleration will differ and as the spaceship comes closer and closer to the planet the acceleration increases.

In first levels, use the up/down keys to control the thrust and the right/left keys to control the direction. On touch screens you can control the rocket through the corresponding on-screen buttons.

In higher levels, you can use the right/left keys to rotate the spaceship. By rotating the spaceship you can trigger an acceleration in non-vertical direction using the up/down keys.

The landing platform is green if your speed is fine for a safe landing.

The accelerometer on the right border shows your rocket's overall vertical acceleration including gravitational force. In the upper green area of the accelerometer your acceleration is higher than the gravitational force, in the lower red area it's lower, and on the blue baseline in the yellow middle area the two forces cancel each other out.

Play checkers against the computer
screenshot checkers icon checkers difficulty level 4

strategy checkers

 Johnny Jazeix & Timothée Giet

Description: The version in GCompris is the international draughts.

Goal: Capture all the pieces of your opponent before your opponent captures all of yours.

Manual: Checkers is played by two opponents, on opposite sides of the gameboard. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent's piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it.
Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. Capturing is mandatory. The player without pieces remaining, or who cannot move due to being blocked, loses the game.
When a man reaches the crownhead or kings row (the farthest row forward), it becomes a king, and is marked by placing an additional piece on top of the first man, and acquires additional powers including the ability to move backwards. If there is a piece in a diagonal that a king can capture, he can move any distance along the diagonal, and may capture an opposing man any distance away by jumping to any of the unoccupied squares immediately beyond it.

 Bruno Coudoin & Timothée Giet

Description:

Manual: In this activity you discover the chess game by playing against the computer. It displays the possible target positions for any selected piece which helps the children understand how pieces moves. At first level the computer is fully random to give more chances to the children. As level increases, the computer plays better.

You can achieve a mate sooner if you follow these simple rules:
Trying to drive your opponent's king in the corner.
Explanation: this way your opponent's king would have only 3 directions to move instead of 8 from a better position.
'Making a trap'. Use your pawns as baits.
Explanation: this way you can lure your opponent out of his 'comfort zone'.
Be patient enough.
Explanation: don't rush too quick, be patient. Let yourself think a little bit and try to predict your opponent's future moves, so that you can catch him or secure your pieces from his attacks.

Play oware against Tux
screenshot oware icon oware difficulty level 2

strategy oware

 Harsh Kumar & Timothée Giet

Description: Play the Oware strategy game against Tux.

Goal: The game starts with four seeds in each house. The objective of the game is to capture more seeds than one's opponent. Since the game has only 48 seeds, capturing 25 is sufficient to win the game. Since there is an even number of seeds, it is possible for the game to end in a draw, where each player has captured 24.

Manual: Players take turns moving the seeds. On a turn, a player chooses one of the six houses under their control. The player removes all seeds from that house, and distributes them, dropping one in each house counter-clockwise from this house, in a process called sowing. Seeds are not distributed into the end scoring houses, nor into the house drawn from. The starting house is always left empty; if it contained 12 (or more) seeds, it is skipped, and the twelfth seed is placed in the next house.

Capturing occurs only when a player brings the count of an opponent's house to exactly two or three with the final seed he sowed in that turn. This always captures the seeds in the corresponding house, and possibly more: if the previous-to-last seed also brought an opponent's house to two or three, these are captured as well, and so on until a house is reached which does not contain two or three seeds or does not belong to the opponent. The captured seeds are placed in the player's scoring house. However, if a move would capture all of an opponent's seeds, the capture is forfeited since this would prevent the opponent from continuing the game, and the seeds are instead left on the board.

If an opponent's houses are all empty, the current player must make a move that gives the opponent seeds. If no such move is possible, the current player captures all seeds in their own territory, ending the game.
