In China, this game is known as jianshiji, which is translated to mean "pick up pebbles." This game was known in Europe as early as the 16th century. Some believe that the name "nim" comes from the German word nimm, which means "take." Did this game develop in both places because of its simplicity? Or did the concept travel from one place to another as global trade increased during the last 1,000 years? We will probably never know the answer to that question, but we do know how to play.
Where did this game originate?
What is strategy?
Are games and math related?
At least 21 pebbles (or beans or buttons...) for each child. The game starts with 12, but the number can grow.
The extension activity will require giving away 24 - 42 pebbles in a ziplock bag.
Send the children home with a bag of pebbles. Ask them to teach a parent or guardian the game. The next day ask if they were able to play together? Did the parent or guardian understand the rules? Did the child explain strategy?
