41 Maths things to do before you’re 12

“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:

MATH JOKE 10: Seriously Funny
January 16, 2019
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.

4. If you are involved in a car chase, hijacking, explosion, volcanic eruption or alien invasion, you will not go into shock.

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.
