This week we started running on the streets for cross country. There are only two big hills that we have to run up on the course and only one is on the practise course so we don't know what the biggest hill is like. Inter house cross country is on the Friday of week four or five I'm not sure which.
This week in maths we learnt about Pi. Pi is 3.14 there are lots more decimal places after this but not very many people can remember them. We use Pi to find the circumference or the perimeter of circles. You need to multiply the diameter of the circle by Pi, the answer is the circumference. We also use Pi to find the area of circles. Instead of using the diameter to find the area we use the radius, you then need to multiply the radius by Pi the answer is the area.
