Fear and Loathing in Grade 3 Math Class

October 29, 2015

Mathspig 5 + 5
Hellooo My Little Luvvies,

So you are in Grade 3. You are asked to do this: Use the repeated multiplication strategy to solve: 5 x 3. Here’s your answer:

……………………………………………………………………..Math homework

……………………………………………………………………..

Firstly, give the kid a cigar. According to The Telegraph, UK the kid is only in Grade 3 and can read: repeated multiplication strategy without their head exploding. Secondly, this kid understands the question.        

5 x 3 = 5 + 5 + 5  except, according to the teacher, this answer is wrong. 

The answer should be:        

3 + 3 + 3 + 3 + 3

……………………………………………………………………..

Maths  think

……………………………………………………………………..

According to The Telegraph : The National Council of Teachers of Mathematics (NCTM) in the US defended how the paper was marked, saying it gives students a better understanding of the problems they are solving.

Of course, the NCTM is suggesting:

5 x 3 = 5 times 3 = 3 + 3 + 3 + 3 + 3

5 x X = 5 times X = X + X + X + X + X

But what about:

X x 3 = ? 

X x 3 = X times 3 = 3 times X = X + X + X

Mathematicians have to think like this! They must be nibble. Mathematicians must think for themselves.

……………………………………………………………………..

CCSS MATH  THINK

……………………………………………………………………..

Too many kids hate maths due to FEAR or BOREDOM. How much would you hate maths if you got correct answers marked WRONG?

And how much would you FEAR the next maths test?

……………………………………………………………………..

National Council of Teachers of Mathematics are Idiots

……………………………………………………………………..

Needless to say, I’m with Bart. Math teachers should not mark right answers wrong for any reason. More reasons why kids hate maths here:  BEWARE OF MATHS FUNDAMENTALISTS

I’m MATHSPIG. I LOVE MATHS.

Cheerio for now

It’s a Knuckle Breaker KNUCKLE HEAD!

January 15, 2014

Australia has a problem with alcohol and violence. Yet another teenager died this week after being King Hit. According to Forensic Toxicologist, Dr Jennifer Pilgrim, in an article titled Australia, we need to talk about alcohol in The Guardian this week

‘ at least 90 young lives have been taken by single hit assaults in Australia since 2000. The overwhelming majority of these involved alcohol and no other drugs.’

While experts argue whether or not Video Games encourage violent behaviour, one fact remains about Hollywood film fight scenes:

This Hollywood Cliché can Kill

Every Hollywood Action Hero gets into a fight. But no human could survive the fight scene punishment shown in the movies.

10 Movie Cliches Debunked with Maths

Cliché 8. You can survive any amount of beating in a fight.

The Hollywood cliche is, of course, not true. One punch can kill.

And if you do the maths you’ll find even a kid can throw a knuckle breaking punch.

5 . Chair Physics or Why Heads Will Roll!!!!

February 4, 2011

Teachers hate kids leaning back on chairs for a good reason.

They may not lose their head, but they could lose a few brain cells if they fall. It’s all to do with angles, but I suggest you use an empty chair or, if you like Myth Busters, perhaps you could use a dummy.


This is not a dummy.


The Centre of Gravity rules for stability apply to a person sitting in a chair is the same way the rules apply to a kid with a backpack.

For more information this is a cool GCSE Physics link using Batman and Centre of Gravity.



This is a really cool school chair trick. The image may not appear on your iPad.

This is just a really cool chair.

9. Canteen Maths or Survival of the Smartest

February 4, 2011

You are on your own here mathspig. But when it comes to canteens you have to be smart, really smart, to survive.


Look at the maths!!!



Avoid that fattening water!!!


Ohh no, not ass pudding again!!!!!

6. Goofy Graphs

October 12, 2010

 Graphs               

When graphs are pretty but provide no real information or are misleading.

Graphs frequently appear in the media with no scales, odd scales or totally misleading scales.

This first graph from the Financial Review: Smart Investor magazine ( Oct 2010) has no scale. You could just scribble a line and call it a graph ( See Above) !!!! Then add a number at the end point to make it look real!

Why use a graph? It’s an investment ad selling an investment product.

The second graph shows that the recent Global Financial Crisis was not so bad. Now look at the y-scale. It’s logarithmic.

Buyer beware of goofy graphs!!!!!

Extrapolation.

Extending a graph or equation beyond defined limits.

Extrapolation is in your head. Just because you have a graph and, maybe, even a formula it doesn’t mean you know all the variables. Put simply, you cannot just extend a graph into the future. You may be right or……. Great Balls of Fire! You could be wrong!


Here is an extract of an article by Jeremy Laurance in The Independent, UK, on 27th April, 2009: 

‘At its worst, it could have a devastating global impact, greater than a terrorist attack, nuclear accident or environmental disaster. The World Health Organisation estimates that a mild pandemic could cause up to 7.5 million deaths.’

If you look at the current count as of 11th October 2011 verified World Wide deaths from Swine Flu are 14, 337. (See Swine Flu Count)


Any death is tragic but according to WHO in a normal year, flu kills 12,000 to 20,000 mainly elderly people in Britain and 250,000 around the world.

9. We’re All Gonna Die!!!!!!!

October 12, 2010

Statistics

Statistics apply to Groups not Individuals

or Why Death Rates are Over-Rated!!!

We’re All Gonna die!!!  Well, um, this statement is true. The morbidity rate for humans is still 100%. Hopefully, you will be happy, healthy and 110 years old before such statistics begin to worry you. 

Newspapers often run statistics stating that your chance of being killed by a shark is 1 in 271,257 as shown. It’s NOT.

Firstly, you know this statistic is a bit dodgy. If you do not go into the water ever you will never be eaten by a shark. You chance of being shark bait is a BIG 0.

Secondly, these statistics apply to groups not to the individual. In every 271,257 Australians 1 MIGHT be eaten by a shark. In 251, 257 surfers the numbers eaten by a shark would be MUCH greater. 

Finally, these numbers still seem high. What?  77 people are killed by sharks in Australia annually. NO. These are statistics over a lifetime. 80 years, say. Less than 1 Aussie a year is killed by sharks on average but just because one surfer has died you cannot say ‘Great! The sharks have reached their annual quota I can go back in the water.’

Statistics can NEVER tell you WHAT might happen to you!

It’s a GROUP THING. All you can learn from these statistics are the  exit-the-earth probabilities for Australians that, mostly, we don’t get to choose.
