GCompris Administration Menu
screenshot administration locked activity

/administration/administration

Description: Left-Click with the mouse to select an activity

Goal: If you want to fine tune GCompris to your needs, you can use the administration module here. The ultimate goal is to provide child-specific reporting for parents and teacher who want to monitor the progress, strengths and needs of their children.

Manual: - In the 'Boards' section you can change the list of activities. Just untoggle them in the treeview. You can change the language used for reading, for example, then the language used for saying the names of colors.
- You can save multiple configurations, and switch between them easily. In the 'Profile' section add a profile, then in the 'Board' section select the profile in the combobox, then select the boards you want to be active. You can add multiple profiles, with different lists of boards, and different languages. You set the default profile in the 'Profile' section, by choosing the profile you want, then clicking on the 'Default' button. You can also choose a profile from the command line.
- You can add users, classes and for each class, you can create groups of users. Note that you can import users from a comma-separated file. Assign one or more groups to a profile, after which those new logins will appear after restarting GCompris. Being able to identify individual children in GCompris means we can provide individual reports. It also recognizes the children as individuals; they can learn to type in and recognize their own usernames (login is configurable).

Description: Select or enter your name to log in to GCompris

Goal: GCompris identifies each child, so we can provide child-specific reports.

Manual: In order to activate the login screen, you must
first add users in the administration part of GCompris.
You access Administration by running 'gcompris -a'.
In Administration, you can create different profiles. In each profile,
you can have a different set of users and select which activities are available to them.
To run GCompris for a specific profile, you use 'gcompris -p profile' where 'profile'
is the name of a profile as you created it in Administration.

Goal: Mix the primary colors to match to the given color

Manual:
The activity deals with mixing primary colors of paint (subtractive mixing).

In case of paints the inks absorb different colors of light falling on it, subtracting it from what you see. The more ink you add, the more light is absorbed, and the darker the combined color gets. We can mix just three primary colors to make many new colors. The primary colors for paint/ink are Cyan (a special shade of blue), Magenta (a special shade of pink), and Yellow.

Description: Understanding acceleration due to gravity.

Goal: Pilot the spaceship towards the green landing area.

Manual:
Acceleration due to 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.

Use the up/down keys to control the thrust and the right/left keys to control direction.

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

Place your satellite
screenshot place_your_satellite icon place_your_satellite difficulty level 4

/experience/place_your_satellite

 Matilda Bernard

Description: Understanding effect of mass and distance on orbital velocity.

Goal: Make sure the satellite does not crash or fly away

Manual:
A satellite revolves around the Earth because of the force between them. Orbital velocity of a satellite of Earth is directly proportional to the square root of the mass of Earth and inversely proportional to the square root of the distance from the center of Earth to the satellite.

In this activity, play with the speed of the satellite and mass of Earth to see what happens to the satellite. If the speed of the satellite is slower than the required orbital speed then the force applied by the Earth on the satellite is too much and thus the satellite gets pulled towards the Earth and burns in it's atmosphere. If the speed of the satellite is more than the required orbital speed then the Earth's force is not enough to keep it in orbit and thus the satellite flies away due to it's own inertia.

/math/algebramenu/gnumchmenu/gnumch-factors

 Joe Neeman

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

Goal: Learn about factors and multiples.

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. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.

Multiple Number Munchers
screenshot gnumch-multiples icon gnumch-multiples difficulty level 3

/math/algebramenu/gnumchmenu/gnumch-multiples

 Joe Neeman

Description: Guide the Number Muncher to all the multiples of the number at the top 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. Again, 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 in 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. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.

Prime Number Munchers
screenshot gnumch-primes icon gnumch-primes difficulty level 6

/math/algebramenu/gnumchmenu/gnumch-primes

 Joe Neeman

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. Use the arrow keys to navigate around the board and to avoid the Troggles. Press the spacebar to eat a number.

Description: Turn the cards over to find two numbers which add up the same, until all the cards are gone.

Prerequisite: Addition

Goal: Practise adding up, until all the cards are gone.

Manual: You can see some cards, but you can't see what's on the other side of them. Each card is hiding an adding-up sum, or the answer to the sum.
An adding-up sum looks like this: 2 + 2 = 4
The numbers on one side of the equals sign (=) have to be the same as the number on the other side. So 2 (1, 2) and 2 more (3, 4) makes 4. Count aloud when you work this out, and count on your fingers, because the more ways you do something, the better you remember it. You can also use blocks, or buttons, or anything you can count. If you have lots of brothers and sisters, you can count them! Or the kids in your class at school. Sing counting songs. Count lots of things, for practice, and you'll be very good at adding-up!

In this game, these cards are hiding the two parts of an adding-up sum (also called an addition sum). You need to find the two parts of the sum, and bring them together again. Click on a card to see what number it's hiding, then try to find the other card that goes with it, to make a whole sum. You can only turn over two cards in one go, so you need to remember where the numbers are hiding, then you can match them when you find their other half. You're doing the job of the equals sign, and the numbers need you to put them together and make a proper sum. When you do that, both those cards disappear! When you've made them all disappear, found all the sums, you've won the game! :)

You're doing the job of the equals sign, and the numbers need you to put them together and make a proper equality. When you do that, both those cards disappear! When you've made them all disappear, found all the operations, you've won the game! :)

Description: Turn the cards over to find two numbers which add up the same, until all the cards are gone.

Prerequisite: Additions

Goal: Practise adding up, until all the cards are gone.

Manual: You can see some cards, but you can't see what's on the other side of them. Each card is hiding an adding-up sum, or the answer to the sum.
An adding-up sum looks like this: 2 + 2 = 4
The numbers on one side of the equals sign (=) have to be the same as the number on the other side. So 2 (1, 2) and 2 more (3, 4) makes 4. Count aloud when you work this out, and count on your fingers, because the more ways you do something, the better you remember it. You can also use blocks, or buttons, or anything you can count. If you have lots of brothers and sisters, you can count them! Or the kids in your class at school. Sing counting songs. Count lots of things, for practice, and you'll be very good at adding-up!

In this game, these cards are hiding the two parts of an adding-up sum (also called an addition sum). You need to find the two parts of the sum, and bring them together again.

While the tangram is often said to be ancient, its existence has only been verified as far back as 1800. It consists of 7 pieces, called tans, which fit together to form a square; taking the square as the unit:
* 5 right isosceles triangles
o 2 small (legs of 1)
o 1 medium size (legs of square root of 2)
o 2 large size (legs of 2)
* 1 square (side of 1)
* 1 parallelogram (sides of 1 and square root of 2)

Manual: Select the tangram to form. Move a piece by dragging it. Right-click on it to create a symmetrical item. Select an item and drag around it to show the rotation you want. Once you've shown what shape you want, the computer will create it. If you need help, click on the shape button, and the border of the shape will be drawn.

Description: Play the Oware strategy game against Tux

Goal: The object of the game is to capture more seeds than one's opponent. Since the game has only 48 seeds, capturing 25 is sufficient to accomplish this. Since there are an even number of seeds, it is possible for the game to end in a draw, where each player has captured 24. The game is over when one player has captured 25 or more seeds, or both players have taken 24 seeds each (draw). If both players agree that the game has been reduced to an endless cycle, each player captures the seeds on their side of the board.

Manual: At the beginning of the game four seeds are placed in each house. Players take turns moving the seeds. In each turn, a player chooses one of the six houses under his or her control. The player removes all seeds from this house, and distributes them, dropping one in each house counter-clockwise from the original house, in a process called sowing. Seeds are not distributed into the end scoring houses, nor into the house drawn from. That is, the starting house is left empty; if it contained 12 seeds, it is skipped, and the twelfth seed is placed in the next house. After a turn, if the last seed was placed into an opponent's house and brought its total to two or three, all the seeds in that house are captured and placed in the player's scoring house (or set aside if the board has no scoring houses). If the previous-to-last seed also brought the total seeds in an opponent's house to two or three, these are captured as well, and so on. However, if a move would capture all an opponent's seeds, the capture is forfeited, and the seeds are instead left on the board, since this would prevent the opponent from continuing the game. The proscription against capturing all an opponent's seeds is related to a more general idea, that one ought to make a move that allows the opponent to continue playing. 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 his/her own territory, ending the game. (Source Wikipedia <http://en.wikipedia.org/wiki/Oware>)
