“**A growing body of research shows us that outdoor play leads to better physical and mental health, has positive effects on cognitive function and learning, and reduces the incidence of behavioural problems**.” Maria Zotti, **Nature Play, SA**.

Peter Dunstan, Principal Kilkenny PS, SA, writes in **SAPPA** magazine, Primary Focus, that outdoor play fosters “**wonderment, independence and freedom**” as well as “**social skills, imagination, creativity and problem solving**”.

Inspired by SAPPA and NaturePlay, Mathspig has produced her own outdoorsy maths list:

We are good at graphs in maths, even funny graphs, but we often forget the power of story telling. Here’s a story about HOW NOT TO DO your MATHS HOMEWORK*.

*NOTE: Homework has never been recorded as the cause of death of a 13 year old.

Here are just a few of the popular disaster movies:

**Avalanche **(2001),** Earthquake **(1974)**, Armageddon **(Involves meteors 1998),** Deep Impact **(More meteors 1998),** 2012 **(Tsunamis, earthquakes, the lot. 2009)**, Twister **(tornadoes 1996), **Backdraft **(Fire. 1991) and** Towering Inferno** (They don’t make thunderous movie titles like that anymore. (1974)

But what percentage of people involved in, say, an explosion suffer from SHOCK! There are many statistics about Post Traumatic Stress Disorder (PTSD) available. In **one excellent study** in The National Centre for PTSD Journal involved an explosion in a paint factory in Norway (1976), the 246 employees were ranked for their exposure to shock as follows:.

A. 66 Narrow escape

B. 59 Involved but not in danger

C. 121 Not present on the day.

80% Group A suffered shock and PTSD. Both Groups A & B showed symptoms of PTSD 7 months later. If, say, a plane crashed into your school sports field and your class survived with minor injuries calculate how many students in your maths class would go into SHOCK and how many would be left to take action using the above statistics.

These stats can also be used as a fraction or decimal exercise using 0.8 or 4/5 as the fraction of students in shock.

NOTE: Many schools in Australia today not only practise fire drills but terrorist attack lockdowns.

# The Math Teacher Knows Everything

### Requirements: 1 die, a fanfare would be nice.

### You will find a fanfare here.

### Ask a student to roll the die, double the number and add 5. He can show the class the number, but not you.

### Ask the student to multiply this number by 5.

### Ask the student to roll the die again and add this number to the total.

### Now you can tell them the numbers they rolled.

### Example:

### N_{1} = 3

### Double: 2N_{1 }= 6

### Add 5: 2N_{1} + 5 = 11

### x5: 5(2N_{1} + 5) = 55

### Roll dice:

### N_{2} = 4

### Add 4:

### 55 + 4 = 59

### The Math Teacher Knows:

### Secretly subtracts 25 from this number:

### 59 – 25 = 34

### Da! Da! There are the two numbers rolled.
