Go to **BASIC MATHEMATICS** here. It will take you through basic maths by your Grade level.

NB. If you can’t remember how to ‘borrow the 1’ for division or ‘carry the 2’ for multiplication here go back to the link above.

**WARNING**: Mona Chalabi INSTAGRAM account is politically graphic and contains sexually explicit graphs. Yeah! Dick graphs etc. The Instagram links in this post connect with individual illustrations.

I found Mona Chalabi through her illustrated New York Times article (7 April, 2022) **9 WAYS TO IMAGINE JEFF BEZOS’ WEALTH.**

So Jeff Bezos personal wealth is $172 Billion (US$) Her Toblerone Block vs Mt Everest comparison was in this article.

NOTE: Median wealth is the mid-point wealth ie. 50% of Americans have more wealth. 50% of Americans have less wealth.

Mona also includes relevant the data in her posts. eg.

** Egg Weight = 7,200 kg = 15,873 lbs**

**Height = 10 m = 34 ft**

**Circumference = 19.6 m = 64 ft**

**The sugar content for easter eggs is: 55-65% by weight**

**So we will assume the sugar content of the giant egg was in the middle:**

This idea comes from Burkard and Giuseppe @ the fabulous MATHOLOGER channel. Students can make a pattern called a cardioid that pops up all over math according to Burkard.

Follow these steps. There is a pdf file below the first diagram for printing exercise sheets.

And then watch the MATHOLOGER video for a really interesting explanation.

**x2 Tables on a Circle pdf file for printing**

**This circle graph blank could also be used for x3 and x4 tables, ****which produce totally different yet equally amazing patterns.**

Halfway there, now it gets tricky. +52 to each point on the circle and keep multiplying by 2.

ie. 27 x 2 = 54, 28 x 2 = 56 and so on.

so 0 = 52, 1 = 53, 2 = 54, 3 = 55, 4 = 56 etc

This shape is called a CARTIOID.

He played drums for Nirvana and is considered by many to be the best drummer in the world. Meanwhile, Taylor Hawkins, the drummer for the Foo Fighters, is also considered one of the best rock drummers ever. **

**In honour of this auspicious occasion and to work out what might be going on inside these rock legends’ heads, I’m reposting (below) the math article about drummers’ brains.**

**In a 2011 article in the New Yorker Burkhard Bilger wrote about neuroscientist David Eagleman and his research into time and the brain especially drummers’ brains.**

**Some of the drummers he has interviewed and/or tested include William Champion of Cold Play, Brian Eno of Roxy Music and Larry Mullen, Jnr of U2.**

**Eno, on keyboards (above) who was working on a U2 album, talks about Mullen’s amazing timing. They were using a click-track (computer generated beat) when mMullen complained he couldn’t drum to it. ENO adjusted the beat. Mullen was happy.**

**ENO adjusted the beat by 6 milliseconds!!!!!!!!! **

**Tempo is measured in beats per minute or bpm. **

**‘Like perfect pitch, which dooms the possessor to hear every false note and flat car horn, perfect timing may just makes a drummer more sensitive to the world’s arrhythmias and repeated patterns, Eagleman said—to the flicker of computer screens and fluorescent lights. Reality, stripped of an extra beat in which the brain orchestrates its signals, isn’t necessarily a livelier place. It’s just filled with badly dubbed television shows.’**

Sides are taken. Arguments are rife. See the excellent article by Donna Lu, **Cracking the formula: how should Australia be teaching maths under the national curriculum?**, The Guardian,13 FEB, 2022)

Should teachers teach? Or students explore problems? (Called Cognitive Activation in academe!)

Why not, both? Then add **outdoor maths** (below) plus **defronting the classroom** sometimes and **try some maths selfies** for homework. More ideas **here**.

It doesn’t matter what’s written in the curriculum, the biggest problem in maths for students is

Here, to tackle boredom are:

“**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:

**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.”**

**According to the fab NBC 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.

Four scores are removed. Two by the random selector (in brackets) and then the top and bottom scores (with line drawn through them)

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:

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!!!!
