Five Things Y'all Mightiness Non Know Virtually The Novel Gcse Content #1

This is the kickoff of 2 posts listing changes to GCSE content that aren't widely known. If you're actually familiar amongst the novel GCSE specification hence you lot likely already know all of this. But if you're worried that you lot powerfulness bring missed something, read on.

1. Graph Transformations
No to a greater extent than stretching of functions. I missed this i hence thank you lot to @MrBenWard for pointing it out today. This is an strange alter - I can't run across the rationale. Here's what's inwards too what's out:
I'm going to bring to edit a lot of resources...

Don't forget that the featured transformations (ie reflections too translations) may every bit good move applied to the graphs of y = sinx too y = cosx.

2. Trial too Improvement
Contrary to pop belief, case too improvement hasn't gone! I idea it had until I saw these tweets from AQA:
AQA's Teaching Guidance says that "students should move able to use systematic case too improvement to honour justice solutions of equations where in that location is no uncomplicated analytical method". 

Any case too improvement questions inwards the novel GCSE may move to a greater extent than challenging than what we're used to, hence nosotros can't rely on by examination questions too resources. Here's an illustration of a novel specification case too improvement interrogation from AQA:
A company has book V = x3 + 2x2 
The book of the company is 90cm3 
Work out the value of x to i decimal place. 
You must exhibit your working.
Note that the interrogation doesn't explicitly tell the pupil to utilization case too improvement, which is a notable alter from previous examination questions.

3. Compound Measures
The novel specification lists pressure nether chemical compound measures - this is novel to maths GCSE. The specification says, "Use chemical compound units such every bit speed, rates of pay, unit of measurement pricing, density too pressure" - run across Question iii inwards this blog post virtually teaching pressure. There are some delineate per unit of measurement area questions inwards the here.
Example interrogation from toticity.co.uk

4. Rounding
It was Mel's post 'Multiplicative counting - the different types'.

AQA provides this illustration question:
"How many numbers betwixt 100 too 200 bring at to the lowest degree i digit that is 7?"
I'm non certain this variety of affair needs straight teaching - it simply needs a logical approach. This instant interrogation from AQA requires the production dominion - I intend it powerfulness move worth spending a lesson or 2 on this (perhaps to a greater extent than if nosotros extend to combinations too permutations - I volition sweat to honour out whether this necessary):
"Daniel has 10 shirts, 8 pairs of trousers too 5 pairs of socks.
a) How many different combinations of shirt, trousers too socks does he have? 
b) He chooses a shirt. How many combinations are in that location now?"
Apart from this lovely PowerPoint from newmrsc on TES, I don't bring much inwards the means of resources for this theme hence delight ship me anything that you lot have!

Formulae
Finally, simply a reminder that your students volition ask to memorise to a greater extent than formulae than they used to. When the novel GCSE was kickoff announced this made the headlines:
"The novel curriculum for GCSE maths volition run across pupils inwards England spending to a greater extent than classtime studying the discipline too memorising mathematical formulae, such every bit Pythagoras's theorem."
Our students bring e'er had to memorise Pythagoras' Theorem too enough of other facts, theorems too formulae. I intend that the behavior on of this alter was exaggerated. Saying that, I volition move annoyed when my students lose marks because they forget the quadratic formula... 

I'm pleased that students volition no longer move required to memorise regal to metric conversions because (unlike times tables, Ms Blower), it's only practical to await these upwards online if ever needed.
I promise that this post has been helpful. Don't forget I bring a page of new GCSE resources too I've written diverse posts virtually novel GCSE topics:

Watch out for my adjacent post when I'll listing 5 to a greater extent than changes that you lot powerfulness non know about.
