Is anyone able to tell me what year level of maths simplifying fractions is in the new National Curriculum?

I imagine knowing 2/4 is the same as 1/2 may be very early primary school level but specifically what year level would the following example be typically from

simplify 18/81

At a quick glance looks like Year 7-8.

you would need to know the 9x tables, long division and fractions, so I'd say year 3-4

I've done that kind of work with my more able grade 5/6s (in Vic), but I agree with Howdo that it's more year 7ish according to the national curriculum.

I currently teach grade 3/4 and a couple of my able kids would be able to do this if shown (it's simple really - divide by common factor of 9 leaves 2/9) but it's certainly not expected at this level.

18/9 and 81/9 is short division, not long division, isn't it?

I am totally surprised by people saying year 7!!

My grade three-r says she does not want to answer ( which probably means that she does not know!) but I would have expected it to be before high school....

I have done problems like that in a grade 5/6 composite and most do pretty ok with it.  I would say it is starting in grade 5/6 and consolidating the skills more in yr 7

DD is in year 4 (NSW) and said they have started doing those this year, but only in her maths group (the top group) as extension work, not the class as a whole. I guess that makes it year 5/6?

Year 4-5, that's a pretty simple example. Son (year 3)was doing that in his 4-5 extension work, quick glance at his ixl exercises (based on the 2010 Australian curriculum) confirms that.

yep, thats exactly why I asked the question because DD has come across it in both Mathletics and IXL in the hard yr 3 or easy yr 4 stuff (so both programs have it placed in the same area) yet it doesnt seem to correlate to where the school seems to think it fits.

Our DD was doing simplification of fractions like that in Year 4.

DS is in yr 3 and his teacher taught them about equivalent fractions this year before the Naplan test.  They didn't do it with 9s though, just 3s, 4s, 5s and 10s.
