Child Maths Homework - Values??

[tgm1974]

Ok so we are doing MATHS homework at the moment and I'm questioning myself if I am doing these sums correctly.

The question is "what is the value of 23, 87, 234, 8453"

Am I correct in saying that 23 is 2 tens and 3 ones?? Is that how it is supposed to be written as the answer?

All the way up to 8453 - should that be wrote 8 thousands, 4 hundreds, 5 tens and 3 ones??

HELP!

It's hard to see how else to interpret the question. I can only assume it's checking that people understand place value, ie 8 on its own means "eight ones", but write 81 and now the 8 means "eight tens". But without knowing the context it's possible that there is something else the teacher had in mind.

I think it's likely to be place value though. In which case the answers you're suggesting seem the most senisble.

Yeah I agree with Jim -wh is kinda lucky since he did 6 y of this at uni

We did this years ago under the category of tens-and-units

so the eight has a different value depending on where it is in a number

We also did Roman numerals - of course - and this gave insight that a number two may have two different numerals 2 and II

Hey Jiim do you think next week they will be doing reverse polish notation ?

I think I'd go back to the teacher and ask what they meant. They seem unable to be clear. One is presently being asked for the value of a list of values !

Meanwhile the value of 23 is 23, the value of 87 is 87, the value of 234 is 234, and the value of 8453 is 8453.

Are you sure that is how the question is worded ? It all seems very strange.

I am wondering if they meant sum rather than value.

The actual question reads "What is the value of each number, 23, 256, 19, 87, 8453"

My son is only 7 and in year 2 so I think it literally is - 23 is 2 tens and 3 ones, 256 is 2 hundreds, 5 tens and 6 ones!!

Lol!!!

If you want to annoy your teacher, tell your kid to start the answer with, "In base ten, the values are..." and then proceed to answer the question properly.

[jim360]

Or even:

"In base n, where n> 8, the values are 23 = 2 n's and 3 ones; 234 = 2 lots of n squared, 3 lots of n and 4 ones..." and so on.

My nephew was given similar homework a few weeks ago. You've got the right idea. He's 7 also.

This should of been explained better by the teacher though, either that or your son wasn't paying attention.

Primary school teachers eh ?
Huh ! They need another training day.

My son "forgets" everything unlwas its xbox related!!

Back in the 1950s we did 'tens and units' then progressed to ' thousands,hundreds , tens and units. I think this is the same, 23 is two tens and three units.
234 is two hundreds three tens and four units. They all follow the same pattern.

[weecalf]

why not just add them up or is that too simple?

[Mamyalynne]

That would work if the question was 'What is the sum of all of these...'

Question is 'What is the value of each of these...'
