Mathematical games

"King of bridges"

"King of bridges" is a puzzle game developed by Grabowski. The cards come in three colors. Pupils discover the cards and connect them with sticks. They build bridges. The one who built the most bridges wins. Children practice counting, determine who has more and who has less. 

Cards come in three suits. The teacher unfolds them by turning over only four cards. Then the children turn them one by one. If the cards that touch their corners or sides are of the same color, they can connect them with a bridge.

"Shut the box"

The aim of the game is to close (or lower) the maximum number of wooden valves (numbers) thanks to the total number of points indicated by the 2 dice.

1. The first player rolls the 2 dice and adds up the points.

2. He must lower the valve(s) corresponding to the sum of the dice. (Example: the dice show 6 and 4, so 10.) The pupil can lower 9 and 1, or 8 and 2, depending on the valves that remain.) All players validate the calculation and the flaps lowered.

3. He rolls the die again, and so on, until he can't lower any more valves.

4. The student adds the remaining numbers and writes the result on his slate.

5. Then it's the turn of the 2nd player, then the 3rd...

6. When all the students in the group have played, the slates are compared: the winner is the one with the lowest number.

"Opération Amon Rê"

“Tonight is the start of Operation Amon-Rê. The four smart burglars break into the museum and defuse the security system by typing the code numbers using very precise calculations. With some additions, multiplications, subtractions or divisions, it is necessary to combine the numbers of the dice in such a way that the results correspond to the digits of the code. Who will succeed first in overcoming all barriers photoelectric and to steal the precious mask of Amun-Re? »

Aim of the game - the players follow a course and try to arrive first at the precious mask of Amon-Rê, at the heart of the museum. To achieve this, everyone must deactivate the laser beams that block the course. At beforehand, care will have been taken to place a "number" tile on each laser beam, representing the code to be defuse.

The first player rolls the 6 dice. By using one or more dice, the player attempts to perform an operation that will give the code of the laser blocking the road in front of his character. An example? The code to cross is 9. You can add die 6 and die 3, or multiply die 3 by the other die 3, or add the dice of value 5, 3 and 1.

If the player manages to get the code, he advances his character to the next laser barrier. The dice used are set aside. The player can attempt to continue the route with the remaining dice. His turn ends when he runs out of dice or there is no solution to defuse the code. Now it's the turn of the next burglar to try his luck by rolling the 6 dice. Small detail of importance: each defused tile is flipped over. On the back is another number, which forces the next burglar to perform other operations!
