Community Maths can involve the school community or the wider, local community. The aim is to get maths out of the classroom and make it a hands-on experience.

Set up displays, posters, demonstrations or art/maths projects in your school library, gym or school yard or take some interesting maths to the local library, strip mall, town hall, local gardens or shopping mall. It will mean planning the project, collecting the materials and making a phone call to the local, say, librarian, but libraries, for instance, welcome community involvement.

Here are just some community maths project ideas.

MATHS POSTERS

Major maths conferences around the world have poster displays. So why not a display of students maths posters in your school library or local library or even a nearby shopping mall. And students should be present at allocated times to explain their poster to other students, parents or members of the public.

Roosevelt Middle School students Jacob Klausner and Oliver Adelson WEST ORANGE, NJ, who were finalists heading to theNational MathCon Competition.

Some of the best middle school maths posters can be found atMathsCareers, UK. Here are some posters from the 2016 competitions.

MATHS DEMONSTRATIONS

Maths students can construct displays that involve interesting maths. The most amazing maths dispalys Mathspig has seen were at the 13e Salon Culture & Jeux Mathematique in Paris. Here is LAGA Phd student Attouchi @ the 13e Salon Culture & Jeux Mathematique in Paris.

She was showing students how to use a graph to create anamorphic projections. More detailed instructionshere!!!

Palestinian Maths teacher Daina Taimina has many zany ideas. You’ll more Creative Maths ideashere.

Mentalist Maths … OK. This may include some Card Tricks … but they’re amazing. You’ll find 10 amazing Mentalist Math Trickshere.

Or let students explore some of the inspiring maths websites and pick a project. You will love the amazing German website IMAGINARY. It’s in English and has some fascinating videos!!!!!

Perhaps students could construct double pendulum like this one demonstrated at the MiMa-Museum, Oberwolfach, Germany. Mathspig can’t stop watching it. Fascinating!!!!!!! The double pendulum has some demanding trigonometry, but at the middle school level the 2D graph traced by the lower pendulum is fascinating enough (Below). And maths can provide equations for this movement. That’s impressive.

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.

The Pixar ﬁlm, Finding Dory, began as storyboard sketches. There were 103,000 drawn for the ﬁlm. The sketches are placed side-by-side in sequence in order to convey scenes and deliver a rough sense of how the story unfolds.

How many 64-page Exercise books would the story board take?

Only one side of the page of the 64-page exercise book would be used for storyboarding.

No. exercise books = 102,000/32=3,187.5

If put into flip Book form the story board sketches would produce a ‘rough’ version of the film.

If you are making a film about, say, Godzilla, you want him to be big. VERY BIG. But he has to share a screen with human characters.

If Godzilla is too big all the humans look like ants.

If he is too small … he looks like a toy TRex.

The Monster Maths:

Height: 108.2m Godzilla’s towering height in the 2014 film—the tallest onscreen incarnation ever

Tail: 167.74m Total length of Godzilla’s spiked tail

Volume: 89,724 m^{3} Godzilla’s total volume in the 2014 film.

Volume: 90,000 tons Godzilla’s volume if filled with water

Teeth: 1.07mLength from the root to the tips of Godzilla’s canine teeth

Teeth: 60 Teeth in Godzilla’s mouth

Roar: 4.83km Approximate distance Godzilla’s roar reverberates. (100,000W Power of the 3.7m-high, 5.5m-wide speaker array from which the sound designers blasted Godzilla’s roar to record the sound in a “real world” context)

Feet: 17.66mTotal width of Godzilla’s feet across the widest point

Feet: 18.18m Length of Godzilla’s footprint from toe to heel

You vs Godzilla

The average height for 14-year-old boys in the U.S. is 164 cm.

For 14-year-old girls in the U.S. the average height is 158.75 cm.

Godzilla = 108.2 m

We’ll assume an average height of, say, 1.6m for a 14 yo.

14 yo =1.6 m

Height:

108.2/1.6 = 67.6 = 68

Footprint

You vs Godzilla’s Footprint

18.18/160 =11.4

Teeth

You vs Godzilla’s Tooth

1.07/1.60 = 0.7

3. 3D Modeling: Polygon Count

3D modeling can be approached in several ways. There is a good explanation here.

One method is to use a 3D scanner to produce a 3D mesh.

Godzilla model under construction

Digital Godzilla as 3D mesh

The mesh consists of polygons. You’ll find everything you want to know about polygons here.

The greater the no. of polygons the better the resolution in a 3D mesh, the better theresolution of the character or object as more shading and texture variation can be added.

So the POLYGON COUNT or POLY COUNT is a measure of the quality of an image.

Here are some POLY COUNTS:

Godzilla

500,000 polygons.

It took the 4 CGI artists 6 months to fully nail the texture of Godzilla’s scales. (See above)

Elysium

Just the space station ran close to 3 trillion polygons.

Transformers 2

Devastator had 13 million polygons

Clash of the Titans

The Kraken had 7 million Polygons.

Avatar

Apart from some bluescreen shots of live-action actors in cockpits, it’s all CG: gunships, missiles, smoke trails, water, fire, an army of photorealistic virtual characters and a giant tree made of 20 million polygons with 1.2 million leaves.

The POLY COUNT is always greater in animated movies than in video games mainly because a higher poly count takes longer and costs more. A higher resolution is needed in a movie as it is shown on a much bigger screen.

Gollum: Game vs Film 3D model

Here are some POLY COUNTS for some popular games:

The Amazing Spiderman

Spiderman – 11,652

Assassin’s Creed 3

Benjamin Franklin – 17,744

Charles Lee – 25,994

Connor Kenway – 28,501

Desmond – 14,934

Haytham Kenya – 19,985

Batman: Arkham City

Batman: Film Version

Batman: Game Model

Batman Beyond suit – 13,050

Harley Quinn – 17,731

Harley Quinn (DLC) – 19,110

Poison Ivy – 15,977

Call of Duty: Black Ops

Frank Woods (full gear) – 19,777

Crysis 2 (console)

Nano suit – 19,073

Multiplayer suit – 27,414
