According to **‘Bored Out of Their Minds’,** an article by ZACHARY JASON in The Harvard Ed Magazine (2017):

**Boredom accounts for nearly a third of the variation in student achievement. **

**Half of high school dropouts cite boredom as their primary motivator for leaving.**

Boredom begins for Math students at Grade 6 when students (Common Core Standards, USA) tackle more abstract concepts such as linear eqns, exponents, probability, geometry and so on.

Math curriculums in the USA, UK & Australia all demand students solve REAL LIFE problems. Too often these are of the type:

Q. Ronaldo has tethered his goat on a 12ft rein in the corner of a 20ft square field. What area can the goat graze?

**THE ANS: Who cares?**

Students really don’t care about Ronaldo’s goat, but here are some questions which involve intriguing answers they might want to work out. And many of these questions involve funny or age-relevant activities, which also helps engagement.

**1. Mean, Median STATS:** **Mean, Median and Coffee: Busting an Urban Myth**

**2. Parabolas: ****Can you beat the 12-14 yo World Record for a Watermelon Pip spit?**

**3. Geometry:** **Build a Freestanding Tower**

**Rates (Speed) & Units:**

**4a.** **The Terrifying Math of Running from a bear**

**5. Decimals, %, Volume:** **What Volume of alcohol is lethal for teens?**

**6. Decimals, Algebra, Weight Units**

**How much blood can a kid lose and survive?**

**7. GEOMETRY. Angles**

**EVEN TEACHERS GET BORED!!!**

The average time it takes **an audience at a conference** to switch off is 11 minutes. Keep in mind this audience is, at least, being paid to be bored witless.

As the weather improves – Spring in Melbourne, my city & Autumn in USA & UK – it is an ideal time to take math outdoors. Here are some fab exercises for Middle School Math.

**Some students will discover their co-ordinate point is not on the grid. Students should then work out that they will need a different scale for the y-axis. You can get more inspiration at the Stand Again blog.**

Aussie Pro surfer, Mick Fanning, grabbed world attention when he was attacked by a shark in the Fanning J-Bay Open, South Africa on Sunday 19 July, 2015. Fanning was knocked off his board and forced to fight for his life. He survived. News.com

One shark expert suggested the shark was a young great white shark under 3.5 m or 12 ft.

According to the Smithsonian National Museum of Natural History:The torpedo shape of the great white is built for speed: up to 35 miles per hour (50 kilometers per hour). And then there are the teeth — 300 total in up to seven rows.

**According to Junior Olympic Games Qualifying Times 2015**

**For 13-14 yo 100m or 328 ft freestyle:**

**t girl = 1.15 or 75sec**

**t boy =1.10. Or 70 sec**

**Let’s assume you are an average swimmer but highly motivated on seeing a shark:**

**t kid = 100 secs**

**So you can swim 100m (328 ft) in 100 sec. But will you survive??????**

We’re sooo tough in Australia! Shark, Smark! Whatever.

Picture from Daily Telegraph

Also according to the Smithsonian: Sharks can detect both the direction and amount of movement made by prey, even from as far as 820 feet (250 meters) away.

But there is hope as, according to the National Geographic Channel, Most shark attacks occur less than 100 feet or 30.5 m from the shore mainly around popular beaches in North America (especially Florida and Hawaii), Australia, and South Africa.

If average swimmer Dav is 100 ft (30 m) offshore and starts swimming when he sees the shark 820 ft (250 m) away, he would swim 63 ft (19.2 m) before the shark attacked. He is still 37 ft offshore. He might make it to shallow water. Or not!!!!

Again we will assume that the swimmer is 30m ( 100 ft) offshore when he sees the shark fin 250m (820 ft) away. But this time we will have the world’s fastest swimmer. This time we are talking Dav Holmes vs Shark!!!!!!!!!

If world champion swimmer Dav starts swimming when he saw the shark 820 ft (250 m) away, he would swim 163 ft (49.6 m) before the shark attacked. He would easily make it to shore before an attack. Dav would be swimming on sand.

Here is an example of Gambler’s Fallacy, but for non-gamblers.

We see – in this case – hear a pattern and then attribute meaning to this pattern – It’s a conspiracy!!!! – when there is no pattern and no meaning!!!!! So Apple found when designing their iPod shuffle feature later on the iPad and iPhone.

“When Apple first introduced the shuffle feature on its iPods, the shuffle was truly random; each song was equally likely to be picked than any other. However, the randomness didn’t *appear *random, since some songs were occasionally repeated, and customers concluded that the feature contained some secret patterns and preferences. As a result, Apple was forced to revise the algorithm. ‘We made it less random to make it feel more random,’ said Steve Jobs, the CEO of Apple’

Try it. Pick 12 songs maybe off your playlist – Your MP3 player, perhaps or a Top 20 Chart or Top 20 Downloads Chart – assign each song a number: 1, 2, 3….up to 12. Take two dice (Diehards Note: It’s 1 die, 2 dice) and roll.

How many throws until you get 2 songs played in a row?

**Weight: 550 lb **

**Height: 8’ 2” **

**Top Speed: 35 mph = 51 ft/s **

**Weight: 1,500 lb **

**Height: 8’ 2” **

**Top Speed: 22 mph = 32 ft/s**** **

**Comparing these speeds to the fastest man on earth, Usain Bolt:**

**Top speed: 27 mph = 40 ft/s **

**In fact, more Americans die each year from choking on their own vomit than are killed by bears.**

**More death stats here. **

**Nevertheless, bears are very fast. So you can see why Park Rangers offer the following advice:**

More information at Mountain Nature.

**The reason for waiting until the bear is 15 ft away is to make sure the spray doesn’t disperse in the air. If the Pepper Spray is too spread out it will not stop the bear.**

**So Usain Bolt could out run a Brown Bear but NOT a Grizzly!**
