MATERIALS: Sheet of paper (eg. A4), ruler, scissors & coloured felt pens.

I am using an Aranea Black Mask Design. We are going to design and make a MATHS MASK PATTERN. If you want to make one out of fabric you will find all the necessary instructions here.

You will find the largest Chocolate Easter Egg ever here.

This egg is 10.39 m high and weighs 7,200 kg , but it is ugly. I like the GUYLIAN GIANT EGG (below) because it looks good and we also know how much sugar is in the egg.

This Giant Egg was made in 2005 in Belgium by chocolate maker Guylian.

Statistics:

Height: 8.32 m

Weight: 1950 kg chocolate

No. Chocolatiers: 26

No. Chocolate bars: 50,000

Total time: 525 hrs

Easter Challenge for Chocoholics

The amount of sugar in the giant egg weighs as much as a Fiat Punto.

One reason why students think maths is a waste of time is because they do not see it in their world. It’s not just middle school students. We are all maths blind.

Here is the challenge. At the beginning of your next maths class:

Ask your students what ‘mathsy’ thing they have on them and see what happens. Mathspig started her ICME 13 Workshop with that question and maths teachers from around the world struggled to answer. Here is what happened.

More ideas below.

Note: I missed the significance of ‘Standing on the Shoulders of Giants’ Quote. It was from the great mathematician Sir Isaac Newton, 1776.

*Flooring: Wood (parallel lines), carpet (tessellations), coefficient of friction (Don’t want people to slip in the wet).

*Windows, doors: Hinges (Fulcrum, Effort as a Hyperbolic function), opening/closing door is an equation of a circle, angles, fly screens (pattern), windows (pulleys sometimes), handles (knob or lever impacts on effort)

Table/desk/chair: Based on statistics to fit majority of students.

Here is a fabulous idea for prompting students to ‘see’ maths in the world. This activity was designed by Axelle Person Faughn, North Carolina University (Below).

The idea is simple.

Ask students to take pictures of maths they see in their lives. The photos below were taken by Axelle’s students.

Alternatively, you can give students an equation and ask them to find a picture representing that equation. Axelle gave Mathspig a slip of paper with the words ‘Demonstrate limits’. I sent back a picture of curly hair and a link to the equation of a helix.

It is hidden, most often, behind screens in computer code. But every so often some magical machine arrives that makes maths visible.

Look at the Marble Machine (below) by Wintergartan a Swedish folktronica band, then ask your students ‘what maths was involved making this machine?’

It didn’t just happen. Some suggestions below.

Maths involved:

*length of xylphone keys. These will be accurately measured to produce the correct note. Ditto width and thickness.

*rate of rotation of gears, wheels

*parabolic path of marble falling on xylophone keys

*ratios of gear wheels

*statistics. The marbles do not always bounce indentically off the keys. So the cup needs to be big enough to capture – what?- 99.99% of the bouncing marbles. I think less. You can count the number of marbles – ball bearings – that have escaped. You can see them on the floor at the end of the video. So you can calculate the % that escape.

*timing (Each element of the machine has to be timed to create the musical effect. Not chaos.)

*Engineering Maths: Strength of laminate. This will have been tested by the manufacturer. Laminates have a much greater tensile strength than one piece of wood.

*Computer Cutting: A program exists to accurately cut out those wheels from a laminate.

*Cost

*How do you buy 2,000 marbles (ball bearings)? Do you count them? You would buy them by weight.

This has to be the best way to save the planet. Yes! Eat up my little lovelies. For every kilo you pack on, you reduce your carbon footprint. Isn’t that the best news for piggies everywhere!!!!! You will find the yummy maths here:

There is sooooo much maths in the news, triumphs and tragedies, I don’t know where to begin.

First of all a tiny little spacecraft not much bigger than a washing machine has landed after a 10 year voyage on a comet 520 million km away from earth. Wow! Mathpig has some interesting space maths for you:

The tragic death of Australian Cricketer Phillip Hughes at only 25 years-of-age after he was hit in the head by a cricket ball, despite wearing a helmet, highlights the danger of some sports.

Many commentators in Australia claimed that the Philae landing was:

This is equivalent to hitting the bullseye of a dartboard in Perth from Sydney. With a billion euro ($1.4bn) dart. While blindfolded (as the mission was powered down for almost the entire journey). ABC The Drum

Actually, hitting the 67P comment was more like roulette as the Rosetta mothership swung into orbit. And, as the earth and the comet are moving, the distance constantly changes, but you can watch the distance changing here.

We will assume someone can stand on earth and throw a dart at the comet … Yes! They would need very big triceps.

So the commentators aren’t even close. It would still be a feat hitting a bullseye with a dart from 160km, but that would be from Sydney to, um, Nowra on the coast.

WHY?

The distance from Sydney to Perth is 4100 km. At best the commentators would be talking about throwing a dart from Brisbane to Adelaide is 2044km (below).
