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:

So you have cracked the WIFI password (above). It’s time for some Fun, Fun, Funnies.

Here are Mathspig’s favourite WIFI names:

Duracell Bunny Arrested

Charged With Battery

Get Your Own Damn Wi-Fi

FBI Surveillance Van 4

Go home tourists

And check the links at the end of this post for a little bit of weird.

Weird 1:

Google Image this number: 241543903

It leads to a meme of people posting ‘put your head in a refigerator’ selfies. Why? Dunno.

Weird 2:

Google: Definition (Defn will do) of ‘askew’.

The Google page is askew!!!! Really. What is the angle of the page below horizontal. You can work it out.

The Simple Maths of a Car used as a Weapon … METRIC units

Berlin Christmas Maraket Attack 2016, ABC

Melbourne Car Attack 2017

Melbourne Car Attack 2017.

Cars (and trucks) have been used as weapons by drivers purposefully driving into crowds including:

2014: Saint-Jean-sur-Richelieu, Quebec

2014 : Jerusalem, Israel.

2016: Nice, France

2016: Berlin, Germany

2017: Jerusalem, Israel

2017: Melbourne, Australia.

What does the maths tell us?

Melbourne is Mathspig’s home town. The car attack killed, tragically, 6 people and injured many more. The question many seem to ask is:

Why can’t people get out of the way?

Look at the video below of the Melbourne car. It doesn’t appear to be going that fast. But the maths tells a different story. You need quite a distance between you and a car travelling at approx 60 kph to have enough time to run clear. (See calculations below)

How fast do you react?

We will set your reaction time at 0.4 sec. This allows time for you to react and turn. If you want to test your reaction time go here. But remember you have to turn as well.

How fast would you run?

According to the Telegraph, UK, the average human can run at 15.9 mph (25.6 kph) and the National Council of Strength and Fitness 15 mph (24.1kph), which Mathspig has rounded off to 25 kph.

How do you escape a car travelling at 60 kph towards you when you are less than 9 m away?

Jump upwards!

You might reduce the impact and even go over the roof.

Look at the video below of the Melbourne car. It doesn’t appear to be going that fast. But the math tells a different story. You need quite a distance between you and a car travelling at approx 35 mph to have enough time to run clear. (See calculations below)

How fast do you react?

We will set your reaction time at 0.4 sec. This allows time for you to react and turn. If you want to test your reaction time go here. But remember you have to turn as well.

How fast would you run?

According to the National Council on Strength and Fitness the average human can run at the speed of 15 miles per hour for short periods of time.

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.

6. Funky, Fab and Fantastic. Yeah! That’s Middle School Maths

Funky, Fab and Fantastic INTRO

Dutch Artist, Theo Jansen’s Strandbeests or Beach Beasts are the most mystical, magical mechanical beasts to walk the earth. And the maths involved is mind boggling with respect to accuracy.

Once again (See 10. Funky, Fab and Fantastic) you can see the maths at work here, but getting it right is tricky.

Here are some of his bigger creatures in action:

But you can build your own Standbeest from a kit that you buy online. This is a wonderful ‘maths’ challenge. And cost is $US10-20 or less. Here is the Strandbeest built by Mr Mathspig.

But you will really appreciate how hard it is to immitate animal movement if you try to construct ONE LEG in balsa wood or icecream sticks. Mathspig took the dimensions of our small Strandbeest (written in mm on each strut) and created this gif using Gifcreator here. Can you make a beast leg walk?

Mathspig gravity plane

We all know about gravity. We worry about gravity.

GRAVITY CHALLENGE

If someone holds a pen in your hand like the gif below, then drops it,

I bet, if you keep your hand in the one position, that you can’t grab it!!!!

The maths is soooo beautiful.

www.GIFCreator.me_OLwVWU

All objects and bodies drop at the same rate of acceleration, g = 9.8 m/sec2

d = distance travelled by falling object (m)

t = time taken (sec)

pen drop formula 1

pen drop formula 2

You can test your reaction time on THE REACTION TIME CLOCK HERE.
