People think that it is the oldest object about history of math. Also, we have Ishango Bone. It dated to the upper paleolithic era. Ishango Bone is the bone of a baboon and it has many notches like a Lebombo bone, but it’s notches are more regular than Lebombo’s. Due to this combination, people believe that this special notches used to show numbers. Today, despite these ideas, there is no certain information about them. 1- What were this bones for ? These bones were for people to calculate something. 2- What evidence is there for this ? These bones been used by people because bones have notches and some of them are regular. Only humans can do it. 3- Do you think these bones belonged to men or to women ? No idea. 4- Do you think these bones belonged to old or young people ? No idea. 5- Why might the above two questions be inapproprite questions to ask ? Firstly, the words woman and man are used for human and bones belonged to baboon so this question sounds weird.

Our topic is meaning of notches. 6- Can you suggest how some object in our modern life that might be misinterpreted if dug up in 20,000 years time. Cannon ball can be misinterpreted. 20,000 years later , people cannot know the wars and they can think that this ball used to play by people such as children or footballer.
