Mean, Median and Coffee: Busting an Urban Myth

April 21, 2017

 

A Fun Maths Exercise.

Students count steps.

No units of length used. 

You can find the free pdf worksheet  (included below) here.

Other fun middle school math(s) worksheets in the Hot Heels series at TpT include

Unit Rates, Angles, Ratios and Algebra.


There is a lot of maths and science behind coffee sloshing in a coffee mug. ‘The human stride has almost exactly the right frequency to drive the natural oscillations of coffee’ explains fluid physicists at the University of California at Santa Barbara. You will find their full explanation here.

Pi in the Movies

March 8, 2017

Pi Day … 14th March ….. 3.14

Pi Day celebrates an AMERICAN Pi because:

1. AUSTRALIA and UK:

Australia and UK write their dates DD/MM/YY and the 14th March or 14.3 is nothing to get excited about.

2. EUROPE

Pi in Europe is pronounced Pee. So 14th March Would be

Pee Day.

And Pee Day would not be something to encourage in Middle School. Also the perfume below is hilarious in Europe.

…………………………………………………….

Nevertheless, here are 2 interesting appearances by Pi in the movies plus a middle school challenge to count the Pi’s in the movie clip.

1. A Beautiful Mind

In this movie where Russell Crowe plays Mathematician Nobel Laureate John Nash, there is a maths  blooper involving Pi. Watch for pi on the window at 43 seconds.

You should have seen 0<π<1. But we all know π = 3.1415 etc.  For those mathematically fastidious an argument can be put that π can be used as a variable, which would make the statement true. But π is a universal constant so using π as a variable is just STUPID.

………………………………………………………….

2. Pi: The Movie

This 1998 psychological thriller promo clip is also the coolest maths promo you will ever see. It is only 1.42 mins long and it is big on π. But be warned the full lenght moive (SPOILER ALERT) involves madness, π and self-lobotomising with a power drill with a ‘happy’ ending.

………………………………..

Pi Day Challenge:

How many times do you see π in this clip? Watch carefully!!!!!

Middle School Maths: WIFI challenge

February 23, 2017

Mathspig spends some time on trains looking at nearby phone HOTSPOT names, so she went out looking for some fun mathsy WIFI names.

Surely,

IT = nerd behaviour = mathsy fun

roni-and-wifi-joke

SHOCK! HORROR! OUTRAGE!

Mathspig searched for days online. She only found 1, ONE, UNO, SINGULARITY, THE LONELIEST No., one vaguely mathsy WIFI funny (below).

Instead of showing WIFI maths funnies, Mathspig came up with a great MIDDLE SCHOOL  MATHS WIFI CHALLENGE.

MIDDLE SCHOOL MATHS

WIFI CHALLENGE

SUMMARY

1. Find a test/worksheet for your class.

eg. Mathcentre NZ have some fabulous Middle School Worksheets with answers. (eg. BELOW)

2. Change your phone name and HOTSPOT password.

3. Test Answer is your WIFI HOTSPOT password!

2-wifi-maths

If you do not know how to rename your phone or change the password, GOOGLE it.

It is easy.

4. When students have worked out their answers and accessed your  HOTSPOT using the password, tell them to go this funny link  Use the Wifi Force, Luke! 

Here is a worksheet example:

Mad Mince Pie Maths

December 13, 2016

Mathematicians can make mountains out of mince pies, but in this case Dr Eugenia Cheng, who is Professor of Pure Mathematics at the University of Sheffield, UK, makes it look fun. The video clip includes some great Middle School Maths that you can eat.

IMAGINARY

IMAGINARY is a German website where ART and MATHS combine. It is AMAZING.

Schools, museums, students, anyone can download interactive Computer Programs like MORENAMENTS (below) to create art, maths demonstrations and public exhibitions. IMAGINARY also contains maths/art films, an art gallery, programs for printing 3D-sculptures, maths texts and exercises, and more.

………………………………………………………

It is FREE.

It is written in ENGLISH.

Here are a few highlights picked by Mathspig, but you have to explore the website yourself.

SURFER

………………………………………………………………….surfer-1surfer-2

 SURFER is a program that allows you to put in any equation and test the resulting 3D image. There is a brief video explaining how it works and you can download the program here.

………………………………………………………………….

WORKSHEETS

You can download worksheets for every school level, but get ready. Here is a worksheet for 5-7 year olds. But why not? Five year olds can look at sheet music without running away screaming, why not show them ALGEBRA too?

Mathematicians Just Wanna Have Fun

The following videos show mathematicians having fun! If your middle-school students think maths is ‘boring’ show them just one of these videos.

 

Explore IMAGINARY. Enjoy.

mathspig-at-icme-hamburg-2016Mathspig tried the m&m Algebra Challenge in her ICME 13 Workshop in Hamburg.

BUT … I bought PEANUT m&ms. OH Nooooooooo!

They were the WRONG SHAPE. Deformed m&ms bounced everywhere. All I could do was collect the m&ms in my gloved hands and hand them out to the workshop participants. They seemed to enjoy the failure.

But Mathspig does not give up that easily.

Here is the m&m ALGEBRA CHALLENGE with PLAIN m&ms.

The Great m+m ALGEBRA CHALLENGE

Method:

1. Open a packet of PLAIN m&ms. (Wear white Gloves like the m+ms)

2. TIP onto table. (Put a few books around the edge to define an area.)

3. Sort the m&ms into:

m -UP pile.

m-DOWN pile.

4. REMOVE the m-UP pile.

5. PICK up m-DOWN pile and TIP again.

6. REPEAT until only 1 m+m is left.

The pattern should follow the exponential equation here:

mm-equation

Did it work? Check it out below.

www-gifcreator-me_qjuoel

Who knew one family packet had 366 m+ms?

You’ll find a worked ‘theoretical’ example here.

Here’s the ANSWER:

Try it. Middle school students have to see

that applying maths in the real world can be tricky but logical.

And a lot of FUN too.

Algebra! Many students struggle with algebra because they see no point doing it. But here is the best fun with algebra you’ll ever have. It is so counter intuitive that you have to see the algebra to believe this trick. Mathspig tried this exercise out on school teachers at her ICME 13  workshop in Hamburg and this is the result filmed – with a few lighting wobbles – on an iphone.

Detailed explanation here.
