MATH JOKE 9: Seriously Funny

MATH JOKE 10: Seriously Funny

We are good at graphs in maths, even funny graphs, but we often forget the power of story telling. Here’s a story about HOW NOT TO DO your MATHS HOMEWORK*.

*NOTE: Homework has never been recorded as the cause of death of a 13 year old.

4. If you are involved in a car chase, hijacking, explosion, volcanic eruption or alien invasion, you will not go into shock.

Here are just a few of the popular disaster movies:
Avalanche (2001), Earthquake (1974), Armageddon (Involves meteors 1998), Deep Impact (More meteors 1998), 2012 (Tsunamis, earthquakes, the lot. 2009), Twister (tornadoes 1996), Backdraft (Fire. 1991) and Towering Inferno (They don’t make thunderous movie titles like that anymore. (1974)  

But what percentage of people involved in, say, an explosion suffer from SHOCK! There are many statistics about Post Traumatic Stress Disorder (PTSD) available. In one excellent study in The National Centre for PTSD Journal involved an explosion in a paint factory in Norway (1976), the 246 employees were ranked for their exposure to shock as follows:.

A. 66 Narrow escape

B. 59 Involved but not in danger

C. 121 Not present on the day.

 80% Group A suffered shock and PTSD. Both Groups A & B showed symptoms of PTSD 7 months later. If, say, a plane crashed into your school sports field and your class survived with minor injuries calculate  how many students in your maths class would go into SHOCK and how many would be left to take action using the above statistics.

These stats can also be used as a fraction or decimal exercise using 0.8 or 4/5 as the fraction of students in shock.

NOTE: Many schools in Australia today not only practise fire drills but terrorist attack lockdowns.

Why Math Teachers should, um, speak proper!

Students can misunderstand teachers.

If math teachers mumble this is the result:

So I’m helping a Year 7 student. Smart kid. This is her test paper. 

NOTE: Students must hear terms clearly pronounced to learn them.

Trick 1: The Great MATHoudini

The Great MATHoudini

Requirements: 1 phone book, Great showmanship

Start by handing one member of the class a sealed envelope. It contains a name that you have seen in your mathematical mind.

All will be revealed at the end of the performance.

Ask one student to write a 3-digit number on the board.

Ask a second student to turn this number around and subtract the smallest number from the largest number.

Ask a third student to turn that number around and add the last two numbers.

Example: N1 = 371.

N2 = 173

N1 – N2 = N3 = 371 – 173 = 198

N4 = 891

N4 – N3 = 891 + 198 = 1089

Give a fourth student a phone book. Ask them to go to page 108 and count down 9 places on the first column and read out the name.

Now open the envelope.

Da! Da!

 

How does it work? The numbers ALWAYS add up to 1089 so you had plenty of time to check out the name in the phone book.

Trick 2: The Math Teacher Knows

……………………………………………………………………………………

The Math Teacher Knows Everything

Requirements: 1 die, a fanfare would be nice.

You will find a fanfare here.

Ask a student to roll the die, double the number and add 5.  He can show the class the number, but not you.

Ask the student to multiply this number by 5.

Ask the student to roll the die again and add this number to the total.

Now you can tell them the numbers they rolled.

Example:

N₁ = 3

Double: 2N₁ = 6

Add 5: 2N₁ + 5 = 11

x5:   5(2N₁ + 5) = 55

Roll dice:

N₂ = 4

Add 4:

55 + 4 = 59

The Math Teacher Knows:

Secretly subtracts 25 from this number:

59 – 25 = 34

Da! Da! There are the two numbers rolled.

Oops! We forgot. Our 1st software Engineer was a Woman!

Margaret Hamilton joined the Apollo Project as NASA’s first computer programmer in 1965!!!

Not only was she the first person to use the term SOFTWARE ENGINEER, her computer programming skills saved the Apollo 11 space capsule from crashing during the 1969 landing on the moon.

She was presented with the PRESIDENTIAL MEDAL OF FREEDOM by President Obama in 2016.
