Just wanted to come back and thank you all. DS got a 5a and was over the moon, he actually got 95%. The teacher gave him a choice to go up to top group but he declined it. I think he did the right thing as he might miss out on things as he doesn't necessarily understand things straightaway and top set moves fast!
He is a hard worker and tries very hard, hence the extra work at home in the lead up to sats.
Thanks to all you wonderful MNetters who helped

I remember doing this at about age 12, so that fits with about y9.

Any idea how I can test him on this tomorrow? Draw another one with different measurements?

Different angles, just move the triangle in an anticlockwise motion so the 12 degrees gets bigger. The way to work it out is the same.

One tip from my slightly dotty maths teacher. When it comes to trig and diagrams write down all you know about it then use that to work it out.

So you ds new each internal angle of the triangle is 60deg, that a right angle is 90 deg etc etc.

Her other advice was to use 'your feminine intuition' - not sure that's such good advice.

Back in my day.... Am getting old!

You also need to bear in mind that the level expected at the end of primary school is level 4. Level 5/6 is the level expected by the end of year 9/the end of KS3, so there will be lots of work covered that is part of the KS3 curriculum.

It seems hard to us when we see it for the first time in decades ... but they do it all in little bits, term after term, year on year, to build up the knowledge gradually. smile

Is anyone else quite shocked/surprised how hard the level 5/6 maths is? I got an A GCSE and def don't think we did much beyond times tables in primary school.

Thanks. Tomorrows revision will be extended if he is up for it. Hugs

YoullNeedATray Thu 04-Apr-13 20:00:29

Sorry - should point out that second link is L5 and L6, so make sure he doesn't get dismayed when he doesn't yet know it all!

Random L5 questions here in SAT format:

Nice online quiz format here, which might be more palatable!

givemeadvice Thu 04-Apr-13 19:23:13

Wonderful ... It all makes sense. Any idea how I can test him on this tomorrow? Draw another one with different measurements?
He is eager for this level 5 .... I'm no teacher though!

(I x-posted with you - ignore that diagram I linked to)

The corner of a rectangle is 90 degrees in total (right angle).

The corner of the triangle is 60 degrees.

The angle marked is 12.

angle x, plus 12, plus the triangle corner, equals a right angle.

amidaiwish Thu 04-Apr-13 19:15:42

I am v rusty but here goes:
The right angle must be 90degrees
The triangle angle is 60degrees
The other side is 12 degrees
So the missing angle is 90-(60+12) = 18

chickensaladagain Thu 04-Apr-13 19:15:08

right angle 90 deg
interior angle of the triange 60 deg


YoullNeedATray Thu 04-Apr-13 19:14:14

Ahh .... is it like this? (move the @ symbol up and down to change the angle that the triangle sits at)

givemeadvice Thu 04-Apr-13 19:11:30

Hope this iPad link works. It is the question of page 15

YoullNeedATray Thu 04-Apr-13 19:07:31

Where is the 12 degree angle? That's a very acute angle! Can you describe how the 12 fits in amongst the right angles of the rectangle and the 60 degree angles of the equilateral triangle?

givemeadvice Thu 04-Apr-13 18:13:37

Following on with more revision .... Please help! This is the last question on today's revision and we can't answer it. It is a level 5 question and ds would like to achieve level5 as he is just off but this revision is definitely showing his areas of need.
Anyway, help us please with this. An equilateral triangle is inside a rectangle. One angle is 12 degrees we then need to work out angle x. Now he knows the triangle has 3 angles of 60 degrees and the right angles 90 so how does he use the 12 degrees to help him? He thinks mumsnet is awesome so please please help him.
Last nights lesson has stuck in his head so I think he will remember lol.

n2 would be n squared, so if n was 5, then n2 would be 25 not 10.

Thanks all. Ds is happy, he got there but will he and me remember this in future? Hugs to all

Thanks Claydavis

To understand the basics, make n a number. Then work out what 5n (5*n) would be and see if it is the same as n+n+n+n+n. try different multiples and different numbers for the n. Demystifies it!

ClayDavis Wed 03-Apr-13 18:54:44

2n is correct.

n+n is the equivalent of 2 times n.

givemeadvice Wed 03-Apr-13 18:53:05

Hi ds is revising for his sats and we have a query. My algebra is v rusty so could someone help with this?
N plus n equivalent is... He thinks 2n but isn't that 2 times n? The only other option is n2.
Also is 6n 6 times a number?
Many thanks
