Learning Jump Strategy from a Young Mathematician

June 8, 2018

Mathpig just learnt this from a young Mathematician age 9.

It is a great way to do maths because you are thinking ‘Mmmm! How can I work these numbers.’

Getting maths students to think about what they are doing is so much better than just having them guess ‘ Arrrr!  Whatever. Click B.’

More jump strategy information here.

This will be very useful later when it comes to a similar method used to simplify long division:

Trick 8: Spooky Maths Magic

May 4, 2018

Spooky Maths Magic

Requirements; Smart board/data projector.

 This is mental maths, but not hard maths. You can play this video by Marco Frezza  directly to the class.

It may not work on everybody, but it would be very interesting to see how many students are fooled by this spooky magic man.

QWERTY Math for MAC

April 16, 2018

QWERTY Math uses KEYBOARD SHORTCUTS

There are 10 math questions

(pdf version and pdf ans below).

The boxed sections are keyboard math symbol shortcuts.

When the students push these keys the Qs finally make sense.

eg. option v = square root sign

BUT:

1. They must have a computer with a KEYBOARD (not a tablet)

2. The computer must be a MAC*

*Mathspig tried to find the QWERTY Math shortcuts on her old PC and it went crazy!!!!

Amazing Maths Clock

March 17, 2018

Albert Digital Mathematical clocks are fascinating.

You calculate the time using +, -, x and ÷ . Such fun and ideal for the math classroom.

Mathspig found the Albert Mathematical clock at the Horsham International Hotel (below).

More info on the Albert Digital Clock here.

You can set the level of difficulty. You get 1 minute to work out the answer and that’s long enough.

Survival Maths: Close encounters with Sharks

January 12, 2018

Drone’s Eye View: AWESOME!!!!!

Australia takes it’s sharks very seriously. Shark detecting drones are being trialled on beaches in NSW as a part of the NSW Government’s $16 million Shark Management Strategy. 

The film JAWS has given sharks a bad rap. Here are the STATS:

Deaths by shark attack in the world:

Australia       About 2 a year

USA               1 every 2 years 

UK                  None EVER

CANADA          None EVER

More deaths occur due to falling off chairs in Australia. Quad bikes are deadly anywhere. 

Full Stats and references here.

Meanwhile,  you see a shark fin. You can swim BUT what distance do you need to be from the shark to make it to the beach.

You will find some interesting maths here.
