Googla på pi day eller pi-dagen eller andra kombinationer så hittar ni massor och ännu mer! Youtube har också massa skoj!

Ni som laddar upp eller ner eller åt sidan något … snälla skicka till mig så skickar jag vidare!

Här kommer lite som jag har hittat . Ibland är det några som inte fungerar. Gör som jag… vänta…. och prova igen lite senare.

Typ allt på denna http://www.piday.org/ Varför bara skicka julkort o något kort från semestern? Här har ni möjligheten att skicka ett pi-dagskort också!

Snabblänk till hur pi kan låta… varning för violinen… http://www.piday.org/topics/videos/

Rap-musik på denna http://www.educationalrap.com/music/pi-day

Lite mattehistoria http://www.youtube.com/watch?v=hJJJmQojcLM

Årets hit… varning för att det fastnar lätt…

Här sjunger de pi-sången baklänges….. Undrar var de börjar på för tal? Ni som kan svara på det får ett pris av mig! http://www.youtube.com/watch?v=fXUDQrOVktY&feature=related

Varning för att ni vrickar tungan om ni provar detta!

My daughter recites 500 digits of pi from memory in about 90 seconds. She learned a total of 2,300, which is also posted. This hit the AP newswire shortly after being posted and she was *almost* a guest on a national morning network news program. (Snott fr sidan)

Varför inte anordna en liten tävling? Hur många decimaler på pi klarar dina elever?

Här kan du få lite tips på hur du kan träna. (Oj vad jag vill ha en sådan tröja!)

Lite mer konkreta tips.

Här hittar ni de 1000 000 första siffrorna i pi.

Till er som vill sjunga själva!

Happy Pi Day
Happy Pi day to you,
Happy Pi day to you,
Happy Pi day everybody,
Happy Pi day to you.
(to the tune of "Happy Birthday")
Oh Number PI
Oh, number Pi
Oh, number Pi
Your digits are unending,
Oh, number Pi
Oh, number Pi
No pattern are you sending.
You're three point one four one five nine,
And even more if we had time,
Oh, number Pi
Oh, number Pi
For circle lengths unbending.
Oh, number Pi
Oh, number Pi
You are a number very sweet,
Oh, number Pi
Oh, number Pi
Your uses are so very neat.
There's 2 Pi r and Pi r squared,
A half a circle and you're there,
Oh, number Pi
Oh, number Pi
We know that Pi's a tasty treat.
(to the tune of "Oh Christmas Tree")
Pi Day Song
Refrain:
Pi day songs
All day long.
Oh, what fun it is,
To sing a jolly pi day song
in a fun math class
like this. (Repeat )
Verse:
Circles in the snow,
Around and round we go.
How far did we have to run?
Diameter times pi! (Refrain )
(to the tune of "Jingle Bells")

Ludolph The Mathematician
(to the tune of Rudolph The Red-Nosed Reindeer)

We know Einstein and Euclid and Sir Isaac Newton
Lifelong devotions there ain’t no disputin’
But do you recall…
The most tireless one of them all?

Ludolph the Mathematician
Had a special thing for Pi
He made it his life’s mission
To help the number specify

All of his fellow teachers
Never understood his plan
To unlock the number’s magic
By calculating it by hand!

Then in 1599,
Ludolph set his goal...
I’ll find digit 35
With geometry as my guide!

Then how the math world loved him
All his hard work helped them see

Ludolph the Mathematician
You’ll go down in history!

(Här hittar ni mer om Ludolph van Ceulen och andra here.)

Oh, Number Pi
(to the tune of O, Christmas Tree)

1. Oh, number Pi, Oh, number Pi
You're truly transcendental.
Oh, number Pi, Oh, number Pi
You're physical and mental.
You stretch the bounds...of all we know,
And tell our circles where to go
Oh, number Pi, Oh, number Pi
Your digits are so gentle.

2. Oh, number Pi, Oh, number Pi
Why can't I learn you faster?
Oh, number Pi, Oh, number Pi
You're really hard to master.
Just when I think...I've got you down
I flip a 6 and 5 around
Oh, number Pi, Oh, number Pi
Numerical disaster!

3. Oh, number Pi, Oh, number Pi
Why are you so specific?
Oh, number Pi, Oh, number Pi
Your digit growth's terrific.
Ten years ago, you had a Mill
And now you're at a couple Trill
Oh, number Pi, Oh, number Pi
You stretch to the Pacific!

Pi Day Time
(to the tune of Silver Bells, starting at "City sidewalks…")

Random digits,
Endless digits
Transcendental in style,
In the air there's a feeling of Pi Day.
Children laughing,
People graphing,
Worry-free for a while,
And in every math classroom you'll hear…

Three one four…
One five nine…
It's Pi Day Time at (our school!).
Three one four…
One five nine…
Savor those numbers, today!

Ring The Bells
(to the tune of Jingle Bells)

Basking in the glow
Of a Math Class holiday.
All we need to know
Is "Pi will lead the way!"

To circles we will sing,
The digits we'll recite
The ratio gives us everything
It's geometry's delight! Oh!

Ring the bells, Pi Day spells
Fun with 3 - 1 - 4!
It's the day to celebrate
That number we adore! Oh!

Ring the bells, Pi Day spells
Fun with 3 - 1 - 4!
First we take one slice of Pi
And then we ask for more!

Math doodling. Lite tidsfördriv och mycket matematik!
