The girls learnt all about the history of Pi - it is believed that the Ancient Egyptians used Pi when they built the Great Pyramid of Giza between 3550 and 2500 BC. The first time Pi was written down was around 1900 BC. Sources show the Babylonians used an approximation of 3 to work out the circumference of a circle from its diameter. In 1550 BC an Egyptian scribe named Ahmes wrote the Rhind Papyrus which included an approximation of Pi of 3.16. The Greek mathematician Archimedes found a method for approximating Pi between 287-212 BC. Once computers were invented, people were asked to estimate Pi far more accurately. As of 2016, the most digits found was, 22,459,157,718,361!
After break, the girls watched a wonderful video entitled 'Sir Circumference and the Dragon of Pi : A Maths Adventure'. They then completed a Pi word search and then had tremendous fun devising sentences using different letter words to symbolise 3.14159. Their final activity was to create a Pi chain with various coloured paper.
Thank you, Miss Hampson, for such an interesting and engaging morning!
Our next SHINE session is after half term on Saturday 2nd March. As we will be in the Chemistry Department, it is vital that girls wear sensible clothes and shoes and to ensure that long hair is tied back.
