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.

A Maths Fairy Tale for Grade 2

May 12, 2016

A Maths FAiry Tale Mathspig

Once upon a time, Grade 2 students did very boring work in maths. And they had to do lots of tests too.

Exam-question-trending-small_trans++qeu1EEj63qgC2KauuzlUjPS5plK0DADLTnlqUSkScwo

Sometimes evil witches wrote the test questions. These Year 2 (Grade 2) questions were very, very scary. Here is one of those very scary questions. It was so scary lots of people turned into angry birds when they saw this question. The angry birds tweeted that this question is ” too hard’. Tweet! Tweet! (The Telegraph , UK, 9 May, 2016)

A very wise old Mathspig worked out the answer.

X -19 +17 = 63

                X = 65

Mmmmm, this is a scary question for Grade 2. 

Many Grade 2 teachers are Wonderful Maths Wizards. They make maths magical and fun everyday. Students must sharpen their pencils and put on their wizards thinking hats to practise their maths. But maths can be magical and fun too. So here is:

A MATHS FAIRY STORY

A Wonderful Maths Wizard teacher can read the story out loud and the little Grade 2 Maths Wizards can write down their answers.

How Oops! Try again Maths is killing us …………………………………………………………………………… MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig ….…. with Kerry Cue

The New Age of Guess-amatics!

Mathspig pill bottle Hellooooo Sweeties,………………………………………………………………………

Some frightening maths this week. When researching DANGEROUS MATHS, Mathspig found one branch of maths is the most dangerous maths of all. Let’s call it GUESS-AMATICS. Today, maths is often taught via computer program packages. Some of these computer packages turn maths into a guessing game.

1 plus 1

This exact and rather frightening scenario was described to me by the mother of a 5 year old. The mother decided it was time to turn the game off. When students play mathematical computer games too often they don’t have to think, they just guess the answer and try again. But be warned this ‘Oops! Try again’ maths can kill you’! Some maths you cannot ‘try again’. You HAVE to get it right the first time. Medication is one area where ‘Oops! Try again maths kills”

Do the Maths and Do NO HARM.

You need sufficient maths to understand medication doses or you might do yourself harm.…………………………………………………………………………………..

And here is just one very frightening statistic:……………………………………..

According to FDA data 1.3 million people in the USA are injured each year from medication errors. Mathspig First Aid Saves

Meanwhile, we need nurses, caregivers, doctors, paramedics, First Aide volunteers, parents, grandparents, babysitters, teachers and all health care professionals to have sufficient maths to be able to calculate simple medication doses. Or we need them to simply READ the dose and make sure it is correct. Unfortunately, many of those who should be able to work out medication doses are either incapable or not paying attention. And your life could be in their hands:

UK

In the UK 1 in 20 hospital deaths is due to medical error. Nearly 12,000 patients die needlessly in hospital every year due to blunders by staff, researchers warn. Drugs or fluid mismanagement  was identified as a problem in 21% of preventable deaths (NHS   2012) or, doing the maths, 21% of 12,000 is approx 2,500 deaths due to bad maths! Mathspig Do meds do maths

USA

According to a new study just out from the prestigious Journal of Patient Safety, four times as many people die from preventable medical errors than we thought, as many as 440,000 a year. Mathspig Do meds do maths

Canada

Reports show between 9,000 and 24,000 hospital deaths due to medical error. Mathspig Do meds do maths

Australia

Official Australian government reports reveal that preventable medical error in hospitals is responsible for 11% of all deaths in Australia or 1 in 9 deaths.

………………………………………………………….

Other DANGEROUS MATHS include:

Dangerous Maths 1:Young drunk dead

Dangerous Maths 2: Death by Snake, Spider, Quad bike, Kangaroo, Raccoon and Vomit

Dangerous Maths 3: Shark Attack

Take care and do the maths……………………………………………………

Dangerous Maths 2: Death by Snake, Spider, Quad bike, Kangaroo, Raccoon and Vomit

August 7, 2015

This post is really a PR exercise for sharks. We fear them. We’re horrified by the thought of being eaten alive!!!. We only have to hear the sound track from JAWS to feel the fear.

Why do we fear sharks? Look at the numbers. REALLY. Show your students. What about stairs??? Quad bikes? Chairs? Bees? That’s when you should feel the fear!!! We are irrational beings. This is why we need maths. We can make rational decisions using maths. There is also a safety message here. The maths speaks for itself. We won’t hammer it.

THE MATHS:

There is lots of maths you can do with these tables.

  • Bar Graphs
  • Pie Charts
  • Ratios (What’s the ratio of death by Snake to Quad Bike?)
  • Fractions (Show death by jet ski to falling down stairs as a fraction)
  • Percentages
  • Powers to the base 10. How many deaths occur in each country per 100,000 or 1 x 10head of population for, say, Quad bikes or ATVs? We can use these numbers to compare death rates and find out how dangerous riding a Quad bike is in each country.

……..Population Data

……..Aust…23 million = 23 x 106

……..USA…319 million = 319 x 106

……..Canada…35 million = 35 x 106

……..UK…64 million = 64 x 106
