# The Great MATHoudini

## Awesome Math Mural

May 28, 2018

This math mural is on a high school wall, somewhere. It works because it has a street art vibe. Not a grade school math book look. That’s cool.

Why not do something like this for your school.

# And film it.

#### from the Ron Clark Academy even includes the lyrics.

You can do this. Make maths ROCK!

The second clip is from WSHA MATH. It is great too.

You will find Mathpig’s Math Song Lyrics here.

And Yes! I have had students singing this maths song

with great enthusiasm.

## 10 CRAZY CREATIVE MATHS BLOGS

April 14, 2016

Background pattern found here.

# 1.

Botanica Mathematica is a Mathematical knitting blog  with patterns included run by Dr Julia Collins and Haggis the Sheep.

# 2.

s a creative maths blog run by Julia Collins and Madeleine Shepherd. Yes! The same Julia Collins as above. It is a small collection of shirts but Big on imagination and this project is something middle school students could tackle using an old shirt. More on Flikr here.

# 3.

The Division by Zero blog is very mathsy. Seriously mathsy. It is run by David Richeson, Professor of Mathematics at Dickinson College. Even though it involves tertiary level maths it is full of curiosities about maths such as this gem below:

I particularly loved the post about Gabriel’s Horn:

And pictures of Gabriel’s horn made out of paper cones. Gabriel’s horn is the surface obtained by revolving the curve y = 1/x for x> or = 1/2 about the -axis. Mathematics professors ‘wow’ introductory calculus students by sharing its paradoxical properties: it has finite volume, but infinite surface area. As they say, “you can fill it with paint, but you can’t paint it.”

The Golden Arches get a working over as well. Are they based on a parabola, Catenary (strung up chain hanging under it’s own weight) or other. It turns out it is other … the Golden Arches fit an ellipse.

# 4.

Visualising Math is a terrific Tumblr feed run by Monica Anuforo and Casey M. both college maths students from Minnesota, USA. I think Monic’a comments on the blog tell us all how important it is to engage Middle School students.

Monica Anuforo: Hello! I’m an 19 year old Nigerian-American female. Obviously, I’m a fan of mathematics. I was one of those people who were lucky enough to find out that MATH IS AWESOME as early as middle school as opposed to later in life.

The Tumblr feed is a fabulous collection of mathematical images including fractals, gifs and jokes. Some of these images (See below) could be drawn, coloured or constructed by Middle School students so they too can discover that maths is awesome!!!

# 5.

Math for Lovers is an anonymous Tumblr feed run by Kcmr. It is an eclectic collection of maths art, gifs and jokes. While it hasn’t been updated for awhile the images are still worth exploring. Here are just two:

Faig Ahmed is an internationally recognized artist from Baku, Azerbaijan, who represented Azerbaijan at the Venice Biennale in 2007. He is well known for his conceptual works that utilize traditional decorative craft and the visual language of carpets into contemporary sculptural works of art.

You have to love a maths blog that announces:

This is why geometry is important kids. It can blow your mind.

This is a brilliant clip of Klemens Torggler’s kinetic art door based on rotating squares. The special invention makes it possible to move the object sideways without the use of tracks.

# 6.

a maths tumblr stream, is oldish and seriously mathsy but some of the stunning visual images and interesting gifs would intrigue Middle school students. e.g. The image below is a screen grab of a circle of dots that rolls around the circumference inside a bigger circle …. but … but .. but … the gif shows that the dots actually only move along the diameters marked. Fas-kin-ating!

Here is another screen shot (above) of a gif tagged Try it. Your mind will be taken over by a higher power.

# 7.

The Advanced Geometry Tumblr stream is a stunning visual feast combining art, geometry and design. By art I mean … could be arty but naked bodies. But exploring the imagery is simply inspiring.

Susan Lombardo created the blog for students in an upper division college geometry course. The beauty of this blog it gives step by step instructions on how to create a crocheted coral reef, adds the maths behind the project and many interesting links.

The Virtual Math Museum links you to some of the most fabulous maths artists in the world including:

Brian Johnston and his Hydrogen Orbital (above)

and Luc Bernard and his Kuen’s Surface:

The background pattern is antagonist from here.

When not writing and hosting Quick and Dirty Tips’ Math Dude podcast, Jason Marshall works as a research scientist at the California Institute of Technology (Caltech) studying the infrared light emitted by starburst galaxies and quasars. Here he is as The Maths Dude:

And here he is as an Astrophysicist dude:

Curiosa Mathematica is run by Jens Bossaert. It shows extraudinary images such as the animation by two cubes  showing the roots of the polynomials x⁵ + tx + 1 and x⁵ + tx² + 1  as t varies. (Shown without animation below) I’d tell you lots more about Jens except his homepage is in Dutch!!!

# 3.

LIFE THROUGH A MATHEMATICIAN’S EYES is a tumblr feed run anonymously but fabulously by a self-described ‘professional mathematical concept disrupter’ who ‘believes that the study of mathematics is like air or water to our technological society’.

Robert Kaplinsky has worked in education since 2003 as a classroom teacher, district math teacher specialist, and University of California Los Angeles (UCLA) instructor. He uses maths to answer some really intrguing questions such as the one below. ‘What was the fastest motorcycle speeding ticket ever?’ is pretty scary!!!!!!!

## Maths Mystery Box 10: LETHAL

February 13, 2015

Middle School Maths Challenge

Symmetry, geometry plus guts and determination.

Make a paper plane that can fly as high as a 5-story building and test it.

You need:

– Half A4 sheet

– Scissors

– A rubber band

The physics of paper is complex. Folder paper is very strong. Here students create a world record folding a piece of paper 13 times.

Crumpled paper is also very strong. Crumple a piece and try and flatten it. More here.

From Instructables blog

Test it but be careful you could take out an eye.

Thanks

# Now for the BIG challenge:

The above paper plane has 5 wing folds. Can you make a bigger paper plane with more folds. For instance, you could try an A4 sheet.

More from Instructables here:
