Help me with DS(7)'s maths homework!

[LightShinesInTheDarkness]

These are the instructions:

Work with a partner:
You will need a set of shuffled 0-20 cards and a sheet of paper each
Take turns to take the top card and put it onto the table in front of you
Write as many subtraction sentences as you can using the number on the card.
The winner is the one who wins the most rounds

Coud you tell me exactly what you would do, please?

ah now I think titchy really has this by the short and curlies - well done! THAT makes sense.

titchy - but how did you know you are limited to sums using the numbers up to 20?

That is a really bad homework task! It is a game to play as a numeracy activity in class surely?

The number of combinations for each round is infinite too, so could go on for ever unes you time it.

My DD is in Y2 and there are definitely used to using 3 digit numbers.

The rules in Op don't say the number sentences should be limited to include onlu the numbers 0-20.

Some of the Y2 children I know are using minus numbers too - so it really could go on for infinite sums!

I'm pretty sure this is a number bonds task for numbers 0-20. I think the point of it is that any addition, even of very long numbers, is just the combination of simpler sums. So getting instinctively familiar with numbers bonds between 0-20 will be very useful for longer sums. Working with 3-digit numbers doesn't really add anything to the task. 120-18 isn't really more difficult than 20-18.

cor, and I thought the teacher was hard to understand - what the hell are you on about, SomeGuy? Is it "new maths teacher" speak? Or is I just fick? (Before you answer that, I'll have you know I have 2 maths 'A' levels )

So do I. I think you can do three actually. They have Additional Further Maths as well. Possibly even a fourth?

I'm not a maths teacher though. Number bonds is one of the buzzwords I've seen them use though. Just means recognising the pairs of numbers that sum to make a certain total.

I think you can do lots of different maths A levels now - when I did mine, it was all lumped together as Maths (Pure and Applied) and Further Maths (Pure and Applied). Shortly afterwards, they introduced Pure, Applied, Pure + Stats, and other variations. With Further options in each as well. But this was a looooong time ago.

I haven't got a school-age child yet, hence not being up to speed with the buzzwords (although if they're talking that level of gibberish, probably just as well )

I think they change it constantly. From what I can tell there is Maths, Pure Maths, Further Maths and Additional Further Maths. But I would imagine Pure Maths is mutually exclusive with the others.

They seem to have come up with something called 'Use of Mathematics'. They could just called it 'Applied Mathematics' but I think it's designed to sound user-friendly and reflect the fact that it's a dumbed down version of Maths.

Perhaps it's like Use of English - we had to do that in 6th form and it was meant to try and increase general literacy, spelling and grammar. ComPLETE waste of my time - 3 hour exam, iirc, that I finished in 45 mins - and we weren't allowed to leave . Mind you, I seem to remember writing a couple of "good" poems on my blotting paper (see, I told you I was Old )

My version of Applied Maths was more like Advanced (for me) Mechanics, so maybe that's why they don't use that term now?

Thumbwitch - I am quite proud of my distinction in 'Use of English' - out-performing the people doing arty A levels when clearly, as a science/maths geek, I should not be able to string a sentence together, was most satisfying . Even if it is an entirely useless qualification which no-one has heard of.

oh me too - I got almost full marks in it despite being a maths/chemistry geek and am still more articulate and pedantic than most other people I know.
