Summer Holidays are done. School is BACK in Australia. But how do middle school teachers get students excited about Maths? Here are some ideas.
“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:
It’s almost summer in Australia. In Melbourne we’ve had floods, mosquito – mozzie- numbers surge and, last Wednesday, I nearly stood on a Tiger Snake that was escaping the floods near the Yarra River!
This post, however, is really a PR exercise for sharks. We fear them. We’re horrified by the thought of being eaten alive!!!. We only have to hear the soundtrack from JAWS to feel the fear. Then we see news footage like the attack below and think it happens all the time. Look at that fin. It’s enormous! But sharks are not THAT dangerous. We really need to look at the statistics to understand the level of threat. See below.
Why do we fear sharks? Look at the numbers. REALLY. Show your students. What about stairs??? Quad bikes? Chairs? Bees? That’s when you should feel the fear!!! We are irrational beings. This is why we need maths. We can make rational decisions using maths. There is also a safety message here. The maths speaks for itself. We won’t hammer it.
THE MATHS:
There is lots of maths you can do with these tables.
Bar Graphs
Pie Charts
Ratios (What’s the ratio of death by Snake to Quad Bike?)
Fractions (Show death by jet ski to falling down stairs as a fraction)
Percentages
Powers to the base 10. How many deaths occur in each country per 100,000 or 1 x 105 head of population for, say, Quad bikes or ATVs? We can use these numbers to compare death rates and find out how dangerous riding a Quad bike is in each country.
According to The Guinness Book of Records the largest chocolate Easter Egg went on display at Le Acciaierie Shopping Centre, in Cortenuova, Italy, on 2011.
It doesn’t matter what’s written in the curriculum, the biggest problem in maths for students is
BOREDOM.
Here, to tackle boredom are:

Nathan Chen, 22, USA, wins GOLD in the Men’s Figure skating with 5 brilliant, soaring quadruple jumps executed to perfection to Elton John’s “Goodbye Yellow Brick Road” and “Rocket Man.”
Nathan Chen’s Winning Performance on You tube HERE.
According to the fabNBC video, Mathletes, nine Figure Skating judges score competitors for the complexity of each element (eg. Triple axel or triple spin jump) and the quality of the performance producing a score out of ten.

This is a typical figure skating score card for one competitor.
The final score, however, is based on the average for only 5 of these scores. Two are eliminated by random selection (Red Brackets). Then the top and bottom scores are removed and the remaining five scores averaged.

Now consider the IDENTICAL SCORE CARDS
of Skater A & B:
Skater A:
Four scores are removed. Two by the random selector (in brackets) and then the top and bottom scores (with line drawn through them)
7.00 + 7.00 + 7.00 + 6.75 + 7.00
……………………………………..
= 34.75/ 5 = 6.95
Skater B:
Four scores are removed. Two by the random selector (in brackets) and then the top and bottom scores (with line drawn through them). But this time the random selector eliminates two low scores.
The average:
7.00 + 7.25 + 7.00 + 7.00 + 7.00
……………………………………..
= 35.25/ 5 = 7.05
Same score cards but Skater B gets a higher average score than Skater A.
Skater A is, in fact, beaten by a random number selector!!!!
