描述： Guide the Number Muncher to all the factors of the number at the bottom of the screen.
目的: 学习倍数和因数。
手动: 一个数的因数是所有可以均分那个数的数字。例如，6 的因数是 1，2，3 和 6。4 不是 6 的因数因为 6 不能分成 4 等份。如果一个数是第二个数的倍数，那么第二个数是第一个数的一个因数。您可以把倍数想成家庭，因数是那些家里的人。所以 1，2，3 和 6 符合 6 家庭，但是 4 属于别的家庭。

描述： Guide the Number Muncher to all the multiples of the number at the bottom of the screen.
目的: 学习倍数和因数。
手动: 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.

描述： 引导吃数怪兽到所有的质数。
目的: 学习质数
手动: 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.

Land safe
sciences experiment land_safe
Matilda Bernard (Gtk+), Holger Kaelberer (Qt Quick) & Timothée Giet
描述： 将宇宙飞船引导到绿色的着陆区域。
目的: Understand the acceleration caused by the gravity.
手动: 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.

描述： Play the Oware strategy game against Tux.
目的: 培养战略思维能力。
手动: 游戏开始时，每个格子里有四颗种子。游戏的目标是比对手捕获更多的种子。由于游戏中总共只有 48 颗种子，捕获 25 颗种子就足以赢得比赛。因为种子数量是偶数，所以游戏有可能以平局结束，即每位玩家都捕获 24 颗种子。
玩家依次轮流移动种子。轮到某玩家时，其需从自己掌控的六个 “屋舍” 中挑选一个。玩家将所选屋舍内的所有种子取出，通过一种名为 “播种” 的操作，沿逆时针方向将这些种子分配到后续的屋舍中。种子既不会被分配到最终计分的屋舍，也不会回到取出种子的那个屋舍。起始的屋舍始终会被留空；若该屋舍原本有 12 颗或更多种子，就跳过此屋舍，把第 12 颗种子放置到下一个屋舍。
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.

手动: 每次从一座塔上拖放最上面的一个圆盘到另一座塔，把左边的塔复制到右边的桩上。圆盘在桩上可以自由来回移动，但要遵循两条规则：每次只能移动一个圆盘；并且大圆盘永远不能放在小圆盘之上。
致谢： The puzzle was invented by the French mathematician Edouard Lucas in 1883. There is a legend about a Hindu temple whose priests were constantly engaged in moving a set of 64 discs according to the rules of the Tower of Hanoi puzzle. According to the legend, the world would end when the priests finished their work. The puzzle is therefore also known as the Tower of Brahma puzzle. It is not clear whether Lucas invented this legend or was inspired by it. (source Wikipedia: https://en.wikipedia.org/wiki/Tower_of_hanoi)
描述： 探索颜料色彩混合。
目的: 学会混合原色颜料以匹配给定的颜色。
手动: 这项活动教导混合基本涂料的颜色如何起作用(减料混合)。
通过移动绘画管上的滑块或点击 + 和 - 按钮来更改颜色。 然后点击“确定”按钮来验证您的答案。
颜料和油墨能够吸收不同颜色的光，剩下的光便是您所看到的颜色。您添加越多的油墨，越多的光线被吸收，得到的组合色就越暗。我们可以只混合 3 种基本色来得到新的颜色。对于颜料/油墨来说，基色包括青色 (一种特别的蓝色)、洋红色 (一种特别的粉红色) 和黄色。

描述： 解决给定的减法。
先决条件: 减法表。
目的: 学习用借位重组法来解决竖式减法。
手动: 在竖式减法中，数字一个写在另一个下方。它们需要从右侧的列开始正确对齐。上面的数字称为被减数：它是我们起始的数量，另一个数要从这个数中减去，以得到差值。下面的数字称为减数：它是要从被减数中减去以得到差值的数。结果写在最下面一行。
要解决减法运算，先从第一列（右侧）的上面数字减去下面数字，然后将结果写在同一列的最下面一行。如果上面的数字小于下面的数字，你可以从下一列的被减数借位：例如，如果你给上面的数字加上 10 个单位，你需要从下一列上面的数字中减去 1 个单位。这就叫做借位分组法。在这个活动中，要做到这一点，请点击上面数字左边的空白矩形，选择 1 ，然后在下一列点击上面数字右边的空白矩形并选择 -1 。然后将该列的结果写在最下面一行，对接下来的列也做同样操作，直到运算完成。一旦你得出结果，点击“确定”按钮来验证你的答案。在某些关卡中，你需要在求解之前写出给定的运算式子；在这种情况下，当运算式子正确写出后，点击“准备就绪”按钮，然后再求解。

描述： 解决给定的减法。
先决条件: 减法表。
目的: 学习用补偿法来解决竖式减法。
手动: 在竖式减法中，数字上下依次书写。从最右边的列开始，它们必须正确对齐。上面的数字称为被减数：它是我们起始的数量，通过从这个数中减去另一个数来得到差值。下面的数字称为减数：它是从被减数中减去以得出差值的数量。结果写在最下面一行。要进行减法运算，请先从最右边第一列的上面数字减去下面数字，然后将结果写在同一列的最下面一行。如果上面的数字小于下面的数字，您可以从下一列的减数借位：例如，如果您给上面的数字加上10个单位，您需要给下一列的下面数字加上 1 个单位。这称为补偿借位法。在本活动中，要实现这一点，点击上面数字左边的空白矩形，选择 1 ，然后在下一列点击下面数字右边的空白矩形并选择 +1 。然后将该列的结果写在最下面一行，对后续各列重复此操作，直到运算完成。一旦得出结果，点击“确定”按钮来验证答案。在某些关卡中，您需要在求解之前写出给定的算式；这种情况下，当算式正确写出后，点击“准备就绪”按钮，然后再进行求解。

描述： 在你的对手吃掉您的所有棋子之前吃掉对手的所有棋子。
目的: 练习下跳棋。
手动: 两对手在游戏板对面玩，一个玩家有黑色的块，另一个则有轻松的块。 玩家交替轮换。玩家不能移动对手的碎片。一次移动包括将一块对角移至附近的无人占用的正方形。 如果邻接的方块包含对手的碎片，且紧接着方块空着的方块， 这块可以通过跳过它来抓住(并从游戏中移除)。
只使用游戏板上的黑色方块。一个块只能沿对角移动到一个未占用的方块。 捕获是强制性的。玩家没有留下碎片，或者因为被阻止而无法移动，就会输掉游戏。
当一个人到达王朝或国王行(最远的一行)时，他就变成一个国王， 其特点是在第一人身上放上一块，获得更多的权力，包括向后移动的能力。 如果对角线中有一块国王可以夺取，他可以沿对角线移动任何距离， 并且可能会在任意距离，通过跳到任何一个未占用的正方形，来抓住敌人。
这个版本的跳棋遵循国际跳棋规则。
