Killer Easter Egg Math

March 30, 2022

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.

 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:

60%

The weight of sugar in the giant egg equals:

What’s the Maths Curriculum got to do with it? WHEN Maths is, like, soooo BORING!!!!!

February 22, 2022

Australia is reviewing its Maths Curriculum.

Sides are taken. Arguments are rife. See the excellent article by Donna LuCracking 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

BOREDOM.

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:

2D Random Walk or doing the Bell Curve Shuffle

July 28, 2021

This is the best Middle School Probability outdoor exercise  EVER!

Equipment:

1 coin per student. 

Instructions:

In the schoolyard, students move back and forward with the flip of a coin. Must be a good flip. This exercise works best with a grid drawn on the schoolyard in chalk, perhaps. (See pic below) If possible film the exercise from above.

Now here are lots of people doing this 2D random Walk on Wall St. The results are totally amazing.

…………………………………………………………

 

Watch for the Bell Curve. It’s AWESOME.

This video was made by The National Museum of Mathematics NY.

Godzilla vs Kong 2021: do the math! … USA Units

January 25, 2021

METRIC version here.

This is the teaser trailer for the Godzilla vs Kong movie out in MAY, 2021. The voiceover is a poem by UK poet W. B. Yeats called The Second Coming.

The poem is a truly horrifying reflection on WW1.

What would happen if a middle school student grew as much as GODZILLA!!!!!!

Might need bigger chairs at school!!!

 The problem for the 2021 film Godzilla vs Kong is that Kong has never been as big as Godzilla even in the obscure 1962 Japanese movie King Kong vs Godzilla (below).

So either The Zilla will have to shrink or Kong will have to grow for the 2021 film.  BUT HOW MUCH should Kong grow? Remember Kong was still a teenager in Kong Skull Island (2017) so he was still growing.
