What age would you say this math work is for?

[Fenicottero]

We've had some work come through today that's a different level than what we're used to. What school age would you say these questions would be for?

"There are 12 eggs in each egg tray and I bought 11 trays.
I used 38 eggs this weekend, how many full trays do I have left now?"

"I need to buy enough whiteboards for 273 students and there are 25 in a pack. When the
packs arrive 17 whiteboards are damaged.
How many whiteboards are undamaged?"

"Mum set off at 5:55pm. She arrived at her destination at 7.34pm. Mum had estimated that
the journey would take her 2 hours and 16 minutes.
What is the difference between her estimated and actual travel time?"

Y3/Y4?

I'm a Secondary maths teacher and they would be suitable for our low prior attaining y7s.

Year 5

Year 5

Mid KS2 I’d say; you need to be able to multiply by 11/12 and understand that there are four 25s in a hundred.

about age 9?

I worked in year 3/4 for many years and that would be suitable for them. Also suitable for the middle/highers in year 2.

My DS is just starting Y3 maths and he couldn't quite do it yet but not far off.

Another vote for year 5. I’m a primary teacher and it’s what my own son in Year 5 would answer now. He’s a little above average in maths, but has improved recently and would get these right now. He’d need some help with the last one as he’d probably get it wrong on his own - time word problems are pretty tricky.
It could be Year 4, for higher attaining children. Having said that, would still find many Year 6 children that would struggle with these two-step word problems. Definitely not Year 3, as they are only expected to recall the 2, 5, 10, 3, 4 and 8 times tables, not 11s and 12s. (My higher attainers in Year 3 would probably get them right though).
So really, it depends on your child!

Mid KS2 I’d say; you need to be able to multiply by 11/12 and understand that there are four 25s in a hundred. No, they teach it visually now so just need a couple of boxes of numicon.

They're counting the groups of 12 - all visual, the highers learn this in year 1!

I'd expect these kind of questions on the yr2 sats

Put it this way, I got my 10 year old son to do a ‘Sats style’ reasoning test paper this week to see how he’s getting in and these questions could have come straight out of it.

Year 4

I've used problems similar to this for my upper range of Year 4s. Towards the end of the year, more of them could do it independently, with a further group needing support.
I would say it's probably standard Yr 5.

Actually, looking closely at them, some are three step word problems - v tricky.

yr 5

I taught Year 4 for 2 years these are exactly the sort of questions they would be given

I'd go year 5 too.

Thank you all, I feel a lot better. This was set for my Y2 child and they wouldn't do it without my help.

*couldn't

It’s beyond Yr2. I‘d have said year 5 doing it on paper. Could be younger with visuals or kinetic type learning etc etc but if a paper task yr5ish.

WELL beyond Year 2!!!

I'm a teacher. Upper KS2.

This is reassuring. There were no visuals, just 10 written down questions all like the ones above.
In the end I wrote the sums and let my child work them out bit by bit, so for Q1:

12 x 11= xxxxx
xxxx - 38 = yyyyy
yyyy / 12 = zzzzz
Round zzzz up to the nearest whole to get the answer.

But even then it was tough as they only know their 2, 3, 4, 5, and 10 times tables. (They know their 11 times table up to 10 x 11)

Age 8-9
By 10, they’re doing algebra.

By 10, they’re doing algebra.

Meaningless statement. Algebra can be f +f =2f, my 3yo can do that.
