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

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

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

Don't forget that the featured transformations (ie reflections together with translations) may likewise hold out applied to the graphs of y = sinx together with y = cosx.

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

Any lawsuit together with improvement questions inwards the novel GCSE may hold out to a greater extent than challenging than what we're used to, therefore nosotros can't rely on yesteryear essay out questions together with resources. Here's an example of a novel specification lawsuit together with improvement interrogation from AQA:
A venture has book V = x3 + 2x2 
The book of the venture is 90cm3 
Work out the value of x to 1 decimal place. 
You must present your working.
Note that the interrogation doesn't explicitly tell the pupil to utilization lawsuit together with improvement, which is a notable alter from previous essay out 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 together with pressure" - run into Question three 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 postal service 'Multiplicative counting - the different types'.

AQA provides this example question:
"How many numbers betwixt 100 together with 200 accept at to the lowest degree 1 digit that is 7?"
I'm non certain this sort of affair needs straight teaching - it only needs a logical approach. This 2nd interrogation from AQA requires the production dominion - I intend it powerfulness hold out worth spending a lesson or 2 on this (perhaps to a greater extent than if nosotros extend to combinations together with permutations - I volition endeavor to honor out whether this necessary):
"Daniel has 10 shirts, 8 pairs of trousers together with 5 pairs of socks.
a) How many different combinations of shirt, trousers together with 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 accept much inwards the agency of resources for this theme therefore delight ship me anything that you lot have!

Formulae
Finally, only a reminder that your students volition bespeak to memorise to a greater extent than formulae than they used to. When the novel GCSE was start announced this made the headlines:
"The novel curriculum for GCSE maths volition run into pupils inwards England spending to a greater extent than classtime studying the champaign of report together with memorising mathematical formulae, such every bit Pythagoras's theorem."
Our students accept e'er had to memorise Pythagoras' Theorem together with enough of other facts, theorems together with formulae. I intend that the deport on of this alter was exaggerated. Saying that, I volition hold out annoyed when my students lose marks because they forget the quadratic formula... 

I'm pleased that students volition no longer hold out required to memorise purplish to metric conversions because (unlike times tables, Ms Blower), it's exclusively practical to hold off these upward online if ever needed.
I promise that this postal service has been helpful. Don't forget I accept a page of new GCSE resources together with I've written diverse posts virtually novel GCSE topics:

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