The first recognizable models were numbers; counting and ‘writing’ numbers is documented since 30,000 BC. These people developed a system of mathematics adequate to determine the cycle of phase of the moon, engraving a primitive graph of this cycle in a bone.

They devise a method of counting. Mathematics was born when ancient man learned how to count.

Archeologists have found a bone with tick marks carved into it. The ticks are arranged into 11 groups of five, suggesting that the bone is used as a tally. One of the artifacts is a wolf bone with many straight notches cut into it.

Between 10000 and 8000 BC in Mesopotamia, people used sets of pebbles as modeling sets.

It is well known that by 2000 BC at least three cultures (Babylon, Egypt, India) had a decent knowledge of mathematics and used mathematical model to improve their every-day life.
