This week in Maths we have been working on world times. We were split up in groups and had to find out how different people knew the time.
My group had to find out how the stone age recorded time!
The stone age!
The stone age was between 5 MYA. MYA stands for millions of years ago.
The Stone age people knew there were 365 days in a year by the position of the stars and planets. When a star or planet was in the same position as the first day of the year a whole year has passed.
When a day went by they put a stone down and at the end of a year they counted all the stones and the anwser was how many days were in a year.
