今天是3月14日，也是π日，是一個適合探索與圓周率相關(guān)數(shù)學問題的完美時機！

P6的學生們和數(shù)學組的老師們在學校的大草坪上進行了與“圓周率”有關(guān)的活動。學生們試圖去解決一些實際性的數(shù)學問題，他們在大草坪內(nèi)利用廣闊的場地，一步步領(lǐng)悟“圓”的魅力。

? 綠地上那棵樹和那7棵樹的木頭體積是多少？那么學校草地上可以種植多少棵樹？

? 如何用繩子和木釘釘出一個完全規(guī)則的多邊形？邊數(shù)為3、4、5、6等的多邊形的周長/直徑比是多少？隨著邊數(shù)的增加，這個比例趨于多少？

? 距離某點6米的點的集合是什么形狀？距離A點2倍于B點的點集或點位是什么？如果我們擴展到三維空間，你會得到什么樣的軌跡？

利用學校的豐富資源，充分調(diào)動學生們的積極性，我們用每一個有趣的節(jié)點，帶領(lǐng)這些無限可能的孩子們走向更深刻的學術(shù)領(lǐng)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?
