今天是3月14日，也是π日，是一個(gè)適合探索與圓周率相關(guān)數(shù)學(xué)問(wèn)題的完美時(shí)機(jī)！

P6的學(xué)生們和數(shù)學(xué)組的老師們?cè)趯W(xué)校的大草坪上進(jìn)行了與“圓周率”有關(guān)的活動(dòng)。學(xué)生們?cè)噲D去解決一些實(shí)際性的數(shù)學(xué)問(wèn)題，他們?cè)诖蟛萜簝?nèi)利用廣闊的場(chǎng)地，一步步領(lǐng)悟“圓”的魅力。

? 綠地上那棵樹(shù)和那7棵樹(shù)的木頭體積是多少？那么學(xué)校草地上可以種植多少棵樹(shù)？

? 如何用繩子和木釘釘出一個(gè)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(zhǎng)/直徑比是多少？隨著邊數(shù)的增加，這個(gè)比例趨于多少？

? 距離某點(diǎn)6米的點(diǎn)的集合是什么形狀？距離A點(diǎn)2倍于B點(diǎn)的點(diǎn)集或點(diǎn)位是什么？如果我們擴(kuò)展到三維空間，你會(huì)得到什么樣的軌跡？

利用學(xué)校的豐富資源，充分調(diào)動(dòng)學(xué)生們的積極性，我們用每一個(gè)有趣的節(jié)點(diǎn)，帶領(lǐng)這些無(wú)限可能的孩子們走向更深刻的學(xué)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?
