the question kind of suggested to me you were taking one of the halfs and halfing that, so I'm in the Eames camp

 

Let me rephrase (as I can't remember the exact phrasing of the guy who told me) but Stevo and Gareth are right in one sense so far.

 

 

Have you seen that 'Are you smarter than a 10 year old' program?

 

Well in the spirit of that, here's a word problem for you all.

 

I have a plank of wood 8 metres long. I cut it in half. Then I cut them in half. Then in half one final time. How many pieces of wood do I have now?

 

How long is each piece of wood?

Sorry, I meant them.

 

So 8m piece.

 

Cut it in half.

 

Then both again. Then again.

 

I was trying to phrase it without giving the answer away. It would be in more child friendly speak in a proper question.

In that case 8x1m lenghts

My other answer, if I was being pedantic about how the question was originally phased (i.e. it wasn't explicitly stated that you kept both halves of the plank after cutting), would have been "1 piece, 50 cms long".

Exactly. I thought it was really interesting how many assumptions we make in maths problems when trying to put things in a real world context (eg the very reason we use word problems). For example, another question that I found interesting was:

 

A boat holds 6 people. There are 74 people. How many boats do you need?

 

This is an attempt to put a division/multiple question in context to show there can't always be a remainder. However, how real is it really? Are all people the same size? Are those 74 people all adults? Disability?

 

Interested me anyway :-)

Yeah but you'd look a right word removed if you got asked that boat question in a maths test and put something like "15 boats. I included 2 extra to allow for wheelchair users"

There's the conundrum.

 

Do we teach children to be lateral thinkers or to learn what they need to pass exams? Big debate raging atm about it.

1) the bloke sailing the boat reduces the capacity to 5 so you'd need 15 boats/trips to transport 74 people.  

EDIT. Clearly I'm a word removed.

1 boat

 

maximise the profit

 

1 boat, get them half way across the Med

 

get another boat

 

repeat

Different subjects though.

 

Surely maths is based on fact, if you like. You can't **** with numbers. They are what they are.

 

Lateral thinking is something else. It's not one or the other.

In calculations yeah. But the purpose of words problems is to put a calculation in a real world context, because more often than not, the average person will need maths in that context rather than a specialised context (accountants, architects etc). And by being so narrow minded with our approach (which everybody does), you're narrowing that 'real world context'. As I said, it's an interesting debate and something I'm going to research further for a paper.

 

And cross-curricular approaches are 'in' at the moment. You'll rarely see a lesson that is just one subject these days.

Ah, yes, the Bowery factor.

Only what they need.  I want to be able to outsmart the rampant gangs of youths when society goes all Mad Max 2.
