My 9yr old grandson's math question....

[Jimaroid]

I think I finally understand the question. I still think it's phrased very poorly but I agree that this...

I believe the way they teach children maths these days is similar to the way I was taught. We used Hundreds, Tens and Units, now they call units 'Ones' So numbers that have two digits and five 'ones' are 15,25,35,45,55,65,75,85,95. So as already said, the answer is 'No' there are nine.

Is correct.

Probably. The answer could also be "No there are ten" if you're supposed to consider a leading zero in a two digit number of 05. But who knows if that's what they're asking given the poorly formed question in the first place.

not poorly formed for the child that is taught about, and understands, 'ones' - then it is perfectly formed

Well thanks guys for the wide range of responses. Like some of us 'old' guard I over complicated the question which, as many of you declared, was a logic issue. There are 9 two digit numbers with 5 'ones' - 5 units. Thus the statement is false the '8' was a red herring.

So despite 3 degrees and a 40yr career in econometrics my grand-kids think I've lost the plot!

What's worse and further proves my stupidity is I should have realised and read the whole task sheet because it was actually my 6 year old grand daughter's homework !!!

I suppose it was a break from the debacle of the politics and perhaps suggests we should send the Westminster and EU numpties to my grand kids school and send the 6 year olds' to run the country.

Just like me.

Oof, it was hardly socket science, too many of you looking for a complicated answer.

I entirely disagree but there you go.

I didn't get it at first - but did when @SR reminded me of how I learned 'sums'.
