今天是3月14日，也是π日，是一个适合探索与圆周率相关数学问题的完美时机！

P6的学生们和数学组的老师们在学校的大草坪上进行了与“圆周率”有关的活动。学生们试图去解决一些实际性的数学问题，他们在大草坪内利用广阔的场地，一步步领悟“圆”的魅力。

▶ 绿地上那棵树和那7棵树的木头体积是多少？那么学校草地上可以种植多少棵树？

▶ 如何用绳子和木钉钉出一个完全规则的多边形？边数为3、4、5、6等的多边形的周长/直径比是多少？随着边数的增加，这个比例趋于多少？

▶ 距离某点6米的点的集合是什么形状？距离A点2倍于B点的点集或点位是什么？如果我们扩展到三维空间，你会得到什么样的轨迹？

利用学校的丰富资源，充分调动学生们的积极性，我们用每一个有趣的节点，带领这些无限可能的孩子们走向更深刻的学术领域。

Today is March the 14th and therefore PI Day(3.14 to 2 decimal places)and so a perfect day for working on PI related maths problems.Prep 6 did exactly this out on the school field with half of the maths team.

The problems included:

▶ What"s the volume of wood in that tree and those 7 trees and how much wood could be grown on the school field?

▶ How can you peg out a perfectly regular polygon using strring and pegs and what is the Perimeter/Diameter ratio of such polygons of 3,4,5,6,etc sides and what does this tend to as the number of sides goes up?

▶ What shape does the set of points 6m from a point make?What is the set of points or locus of points which are two times as far from point A as point B?What loci do you get if we extend to 3 dimensions?
