1. Tube Cube

February 17, 2016

10 Amazing ways to see a cube

The Tube Cube is made from straws and hat elastic (Steps 1 – 9 below). The effect is quite amazing. The TUBE CUBE can then be used to make a CUBIC BUBBLE here.

Don’t show your Middle School students these instructions. Just give them access to some straws, hat elastic, rulers and scissors and ask them to make and then photograph their cube. That’s the challenge Mathspiggies. But the end result (See  Step 9) is awesome.

Step 8: The TUBE CUBE can be flatened into a hexagon.

Step 9: The TUBE CUBE can be turned into an art work. This pic was taken in daylight.  The cube was positioned at an angle on a black sheet of paper with one corner set in Blu Tack. WOW!

2. Folded Paper Cube

10 Amazing ways to see a cube

You can find a number of ways to fold an origami cube on the web. Jeremey Shafer will show you how to fold a seamless cube (below) here.

It’s a bit tricky. Wikihow has very clear instructions on how to fold a simple paper cube here.

But, Mathspig prefers the paper cube designed by Phillip Stromberg of the Netherlands.His cube calendar (below) comes inside one of these paper cubes. This was a very spooky calendar as Mathspig could see her life disappearing in front of her eyes for one whole year. ARrrrgh!

Stromberg Cube Calendar

Here is the way to fold a Phillip Stromberg cube:

Mathspig Cube 2.1

Step 1: Draw up a grid on cardboard 7 x 6 square.

Mathspig used 8 cm squares on paper. Cardboard would make a stronger cube.

Mathspig Cube 2.2

Step 2: Count of squares and draw this pattern.

Mathspig Cube 2.3

Step 3: Cut out the cube template.

Mathspig Cube 2.4

Step 4: Use scissors to score all folding edges.

Mathspig Cube 2.5

Step 5: Score the perpendicular bisectors of the isoceles triangles. Ha Ha! I’ve always wanted to say that!!!!

Mathspig Cube 2.6

Step 6: Fold the cube sides up, tucking the extended flaps over the triangles.

Mathspig Cube 2.7

Step 6: Fold down the cube lid!!!

OK! It may take some practice. But mathspig likes her cube.

Maths isn’t TOO HARD; it’s TOO BORING, Sir!

Lego Mathspig 2

Hello my little Peeps,

In 2012 The New York Times ran an article by Andrew Hacker titled ‘Is Algebra Necessary?’ The argument was, basically, that too many students find algebra difficult and colleges in America use math results to screen students thus further disadvanting already disadvantaged students. The author had a point. eg. Of all who embark on higher education, only 58 percent end up with bachelor’s degrees. The main impediment to graduation: freshman math.

Perhaps, algebra could be taught in a different way. Mathspig was inspired by New York Grade 3 teacher, Alycia Zimmerman, who uses Lego to teach fractions (See next post) and came up with the following examples.

Lego Mean, Median and Mode

Lego Algebra

But Mathspig has always lerved Lego Maths. Here are just a few examples;

Ratios: Lego Olympics

Ratios: The Rosetta Project Scaled down to a Lego Universe

Other links to Lego Maths.

And while you are doing your Lego Maths you an also use the Lego Template to design your own Lego Figurine.

You get to be DIVA for a DAY.

Everything you do is LARGER THAN LIFE.

You get to talk melodically, over act and  every now and again answer questions in an  Operatic Style. 

The rooms are alive with the sound of music …La La La Lala
