They take their maths seriously in Germany. They have monuments to mathematicians. They name streets after mathematicians. They take maths into shopping malls.

They think maths is so important they even put maths on stairs. Here is some times tables art from Germany.

Mathspig is a writer by trade and I’ve suddenly seen the parallels between Street Art and Writing.

But as Mathspig I am gobsmacked to find street artists devoted to mathematics too. Woo Hoo! More street art in my Kerry Cue Author Twitter feed. Click on sidebar.

Street Art by German Case of the Maclaim Crew, East Harlem, NY

Why not paint a maths mural of your own at school?

Mathspig was walking down a street in her home town, Melbourne, when she came across this Street Art piece on a wall of an auto-repair shop in Lygon St, Brunswick.

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.

The Maths Mystery Box is a great treasure chest to take into maths classes. It can be used an an extension exercise or to engage some disengaged students.

……………………………………….

The IDEA is to use concrete objects and write a maths problem to go with the object. (See examples below) The appeal of the MATHS MYSTERY BOX is that it involves CONCRETE THINKING, sort of. All text books involve ABSTRACT thinking, which some students do not like.

…………………………………………….

A student picks a maths problem from the box. A problem can be simple or complex. But it is not just a maths problem. The student gets to hold an object in their hand. They have to devise their own method of approach. And they must be resourceful. ie. use equipment at hand eg. their phone as a stop watch. Students like this activity. Even maths teachers like this activity as Mathspig found out at her workshop in Hamburg.
