## Day 100 of World Wide Covid-19 data.

## Finally, the **New York Times** published graphs that show the severity of the Coronavirus death rate compared with average weekly death rates. Here is the graph for New York City, which shows during the peak of the Covid-19 Crisis there were 6,000 more deaths per week than expected from the average weekly death rate, which was approx. 1,000.

## The death rate was 6 times the average death rate. That is a terrifying statistic and explains why we are all in lockdown or are slowly coming out of lockdown. Meanwhile, in the rest of the world death tolls are still increasing.

## Many statisticians are using 3-day and 7-day averages to track the Covid-19 death and infection rates worldwide.

## Mathspig is using the total average of deaths per day since stats were first published from 22 JAN 2020. When this average drops … that will be a sign for cautious optimism. But not yet!!!!

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?**

# Simple.

# Ask students maths questions which have answers they want to know.

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**

**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?**

**USA UNITS**

**Metric Units**

**7. GEOMETRY. Angles**

**Any Topic:**

**8.** **Middle School Math Photo Scavenger Hunt**

**9**.** Write Your Own Math Song**

**10.** **Make a Math Poster**

**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.

It’s Autumn in UK & FALL in the USA so it’s the perfect time for a little bit of outdoor math for Grade 3-5 with AUTUMN leaves. Of course, you don’t need FALL LEAVES for this exercise, but it is colorful.

**This fab idea comes from Juliet Robertson, an outdoor education consultant in Scotland. ****Her blog Creative star learning is one of the most inspiring outdoor maths blogs you will find.**

Check out Mathpig’s protractor joke here.

**Another fab idea from Juliet Robertson.**

The follicle diagram (above) came from bgoffforensics blog. More on hair growth rates here.

**QUESTION 1:**

## How long to grow that really bad 70s style hair cut?

The length of Fabio’s hair (below) is approx 50cm.

t = 50/1.25 months

t=40 months

## t = 3 Years 4 months!!!!

## Is it worth the effort? Ha!

**QUESTION 2: **

The growth rates of 1.25 cm/month or 0.5 inches/month are rounded off. Calculations using these growth rates will produce different answers for very large numbers (as above). Read more about the above story in the Daily Mail, UK here. By the way, Asha has been growing her hair for 25 years. Her hair weighs 3 stone or 19 kg. You can find more hair records including the World’s longest ear hair here.

**QUESTION 3:**

Natasha lives in Rio de Janeiro, Brazil. Read more about Natasha in the Daily Mail here. Once again Mathspig has rounded off the length of hair for easy calculation. The Daily Mail puts Natasha’s ‘mane’ at 5 feet 2 inches or 157 cm. This is the length of hair to be cut off. So Mathspig adjusted the length to 180cm or the approx length of her longest hair.
