Core Maths in summer 2020 – what we know

Well, that was unexpected! I won’t go over the same things you’ve no doubt read many times already but I will say that I hope you and your loved ones are safe and well.

We are starting to find out about how GCSEs and A levels are going to be handled but I still have a number of unanswered questions about Core Maths qualifications.

In this post, I want to collate those questions and provide answers where/when I can find them. I will only use reliable sources (ie Ofqual, DfE, Exam boards) and will avoid speculation. If you have your own questions, please post them in the comments or tweet them to me. If you have links to answers to any of these, please let me know as well.


Are Core Maths exams going ahead?

No. From the Ofqual press release: (emphasis is mine).

This year’s summer exam series, including A levels, GCSEs and other qualifications, and all primary assessments, have been cancelled as we fight to stop the spread of coronavirus.

Will Core Maths students get a grade?

That isn’t 100% clear but the answer seems to be “yes”. From the Ofqual press release: (emphasis is mine).

This means ensuring GCSE, A and AS level students are awarded a grade which fairly reflects the work that they have put in.

I note that Core Maths is not, technically an AS level. It may well be phrased like this as a simplification.

There is a very wide range of different vocational and technical qualifications as well as other academic qualifications for which students were expecting to sit exams this summer. These are offered by a large number of awarding organisations, and have differing assessment approaches – in many cases students will already have completed modules or non-exam assessment which could provide evidence to award a grade. We are encouraging these organisations to show the maximum possible flexibility and pragmatism to ensure students are not disadvantaged. Ofqual is working urgently with the sector to explore options and we will work with them to provide more details shortly.

This is the part that makes me think they will be given a grade.

Core Maths is taken in year 12 at my establishment. Will they get a grade?

That isn’t entirely clear but the answer seems to be “yes” based on the things above.

Will year 12 Core Maths student be able to take the exam next year?

Still not entirely clear but seems to be a “yes”.

In addition, if they do not feel their calculated grade reflects their performance, they will have the opportunity to sit an exam at the earliest reasonable opportunity, once schools are open again. Students will also have the option to sit their exams in summer 2021.

At the very least, I can’t see any reason why current year 12 students would not be able to take the qualification in the Summer 2021 series.

If there are additional opportunities to take the exam (early next academic year) will they use the same preliminary material?

There’s no information on this yet.

My students take Core Maths in year 12. Should they be continuing to try and study the course from home?

There’s no real way to answer that. You’ll have to be guided by your establishment.


Once again, if you have your own questions or answers I can add to this please let me know.

I’ll finish with a kind of Core Maths question. “How much more water is being used per day now that people are washing their hands properly?”

Mortgage calculations

In the most recent Core Maths exam for AQA, they made use of a scary-looking mortgage repayment formula.

Now, I don’t think it’s really that bad but it is a challenging substitution formula for anyone that isn’t very confident with maths. It’s also a fair bit of a challenge to be able to use a calculator correctly with a formula as complex as that one.

I think that future exams may make use of other complex looking financial formulae so I’ll try to see what else is out there as possible candidates. While I don’t think that AQA will be using this particular formula again any time soon, I have written a few questions that you might like to use so that students can (hopefully) become less fearful of complicated substitutions. (Both files are the same, just different formats.)

Do let me know if these are any use and if you find some other financial formula candidates!

Critical Analysis – Claims about France

In my scheme of work for Core Maths, I have a two week slot near the end for Critical Analysis. My original thinking was that I’d use the preliminary material as the catalyst since the questions are most likely to be about them anyway.

I was hoping/intending to weave some critical analysis throughout the course and that’s one of my main aims for this year. We’re working on estimation at the moment and this leaflet came in a gift box I received.

I think that points 4 and 10 both have opportunities for fact checking. 4 seems intuitively unlikely to me but I’d like to know more. 10 sounds believable but I think there’s something about “well, how many would that be per day?” That could help check its validity. Seems like a useful skill to develop for helping with newspaper headings.

I can’t quite put my finger on why these feel like they belong in the estimation section of my SoW but that’s where they’re going.

Do share your own critical analysis activities please!

Back to School – The New Normal

My school started back last week:

  • Tues was Inset
  • Weds we had just year 7 and 12 in
  • Thursday was years 7, 11, 12 and 13
  • Friday was with everyone.

There were clearly quite a lot of nervous people, both staff and students, and a fair bit of uncertainty around some things but that was to be expected and I think can only really be found out when things actually start.

While I’m not a fan of the phrase “The New Normal”, I can tell you that I found that most things really were surprisingly close to “The Old Normal”. Aside from some extra hand sanitising on the way in and out of classrooms the actual lessons felt pretty normal to me. I tried to just get on an do some maths with my classes and honestly, it felt a lot like back to being an “Old, Normal Teacher”.

If you’re worried about all the rules at your school, I’m going to tentatively suggest to you – don’t worry, things will be fine!

Core Maths lesson 1 – September 2020

Hi everyone and welcome back to my blog.

What a year eh? Let’s not dwell on that and get in to some nice Core Maths work. This post has what I’m intending to use with my classes (and for the first time I have a second teacher with a class).

I’ve chosen to use the Corona virus as the theme for the first lesson. Here are my reasons:

  • I think that to ignore it would feel weird
  • I’ve picked some aspects that are relatively light hearted (to avoid issue of students that have suffered losses)
  • I normally launch straight into the course but there are always students that chop and change subjects. These are a nice couple of activities that aren’t vital if they’re missed!

The lesson uses hand sanitiser to have a quick ‘which is best value’ question and also introduce that massive Core Maths aspect of , “Well, it kind of depends what you mean…”

I’ve also looked at toilet roll because it was such a massive issue and there’s some good maths to be had there. You could, of course, use Mark’s QUIBANs on it if you like.

As ever, please use and adapt as you wish. If you have better ideas that I can use then please share.

If you are new to the blog, please leave a comment and subscribe – it’s always nice to hear from people!

Wrong but Useful podcast – the end of an era

Today sees the release of the final episode of the podcast I’ve been recording with Colin for 7 years.

You can listen to it here

We’ve talked about a lot of maths over the years and had special guest co hosts that try to represent people from a broader demographic than Colin and I. It’s a good time to point out that Colin did the vast, vast bulk the co host finding work here and I’m grateful for that.

If you didn’t know I recorded a podcast, you might like to check out the back episodes.

We started the podcast to fill a gap in the maths podcasting world and there are now, fortunately, a number of other options available. Colin and I still like each other and haven’t ruled out working together in the future but it was time for this podcast to come to its end.

I have got loose plans for a new podcast with more of a focus on maths education. Given where we are in the world now, I don’t think it’ll happen any time soon but I’m sure I’ll mention it here when it does.

Thank you to all of the listeners and anyone who has contributed with suggestions for items to discuss. Thanks also to the (approximately) 40 special guest co hosts – it has been wonderful to be able to talk maths with such a great bunch of people.

Finally, thanks to Colin for all he’s done and for being willing to talk to me every month. If you weren’t aware, Colin writes books and they are actually good. Available in all good book stores, some less good book stores and probably your local library too.

So, this has been episodes 1 to n of Wrong, but Useful. I’m @reflectivemaths, that’s Dave in real life. Cheerio!

(Now, how do we get into pretending this didn’t happen?)

Core Maths Estimation Question

Here’s a slightly different approach to asking an estimation question and I’m using it with my year 11s going into year 12 next week.

It occurred to me that while getting an average/estimated result for something is certainly useful, there may well be times when knowing what reasonable boundaries are. There’s probably a loose link here to the idea of confidence intervals too.

Bonus points if you can work out what Len’s accent is!

Bridging work for Core Maths – year 11 into 12

If you’re anything like me, you’ll have a lot of people tell you that things are very weird at the moment. There’s no denying this at all and one of the aspects a number of teachers are trying to deal with is that of helping get students ready for the beginning of their courses in year 12. In this post I’ll outline what my school has done and then be more specific about the Core Maths tasks.


Whole school approach

I’m really pleased with the way my school has handled the transition work. We already had our applications in for 6th form so, students have been put into classes on SIMS based on their options. We have been able to include external candidates as guest students so they are not missing out. The classes appear on the relevant teachers’ timetable in a new “lesson 6” slot. (We have 5 lessons a day and are not moving to 6, this is just a temporary thing.)

Each subject is responsible for setting appropriate work to help them bridge the gap between year 11, especially finishing early, and the start of year 12.


Core maths

There are 5 weeks in this term so I’m setting five chunks of work with the help of the KS5 coordinator, Elliot. We are looking to strike a balance between introducing some new aspects and brushing up on some of the most important fundamentals.

We are using Google Classrooms so all of the tasks are set and handed in on there with all of the students being in one single class for the sake of this.

Introduction

I recorded a short audio for them to listen to. I can’t upload it here but if you want to hear it, get in touch and I’ll see if I can send it to you. (It’s only 1 minute long and basically says “Welcome. Tell me why you chose Core Maths.”)

Week 1 – Estimation

Task 1 – Mental arithmetic warm up. Complete the 30 seconds challenge (like these ones here) and type the answers into a google forms quiz.

Task 2 – Read the extracts of Rob Eastaway’s book Maths on the Back of an Envelope. Then leave a comment giving an example of when estimating might be useful.

Task 3 – “What is the total value of all the boxed Easter Eggs sold in England this year?” Answer this and submit a picture of their working. I told them not to just google the answer but it was ok to google something like “What’s the population of England?” I’m marking this and giving them (very positive) feedback.

Task 4 – Optional extra. Looking ahead to next week. Percentages revision.

Week 2 – Percentages practice

Look at these two examples of percentages being used in the news (here and here).

“Their report ‘Parenting Generation Game,’ says 81 percent of under-18s in the UK regularly play online games, but only 58 percent of parents have tried it for themselves.”

  • Does that 81% value fit with what you’d expect?
  • Give an example of why writing ‘online games’ is not very clear

Forty-nine percent of male parents agreed that gaming was a valid form of quality time with their child, while only 39 percent of female parents felt the same way.

  • In your view, is 49% much different to 39% in this context?

From the jobs article:

The overall results show they are three times more likely to want to be a YouTuber (29%) than an Astronaut (11%)

  • Is it acceptable to say that 29% is “three times more” than 11% ?

After this, I’ll put some percentage revision questions (these ones) into a google quiz for them to answer.

Week 3 – Critical analysis with QUIBANS

Two fairly short tasks based heavily on Mark Dawes‘ QUIBANS blog posts:

Christmas Chocolate recycling

European Royal Families

I’ll probably simplify these a little and give my students a bit more structure as I’m not there to talk them through.

Week 4 – Budgeting

Some questions taken from this article about ‘money maths’.

I’d like to put a simple budgeting task in here. It’ll be something like getting them to think about what monthly expenditures they’ll probably have to think about when they’re adults, then trying to figure out the general price of some of them. Finally, how much does that come to in a year.

Week 5 – The Power of Data

Search for a news website and tell me the name of the first type of graph you see. (Data representations are used all the time.)

Watch Hans Rosling’s amazing video 200 years in 4 minutes.

  • What have you learnt about the world that you didn’t know before? (Not a Core Maths Question as such but still.)
  • Describe one way in which having the graphs makes it better than a table of values.

Then, two options to do with histograms (I haven’t found these resources yet):

  •  A simple intro to histograms for those that haven’t done them before,
  • A more advanced question for students that have seen them before.

These aren’t set in stone, especially the later ones so if you have any good ideas, I’d like to hear them.

I hope these plans are of use to you and if there are any you particularly like, let me know!

 

Critical Analysis – Royal Mail

royal-mail

Nice and simple fact-checking task this one. You can see in the image that Royal Mail claim to deliver 16 billion items every year. Does that sound believable?

Here are some prompts if needed:

  • Is this just household post or business too?
  • Letters and parcels?
  • Are they counting ones delivered abroad?
  • How many letters does a school send in a year?
  • How many Christmas cards does your house get?
  • Are the ones to Santa ‘delivered’?

 

  • Extension -how much money would they take in postage?

Preliminary Material – Initial Thoughts

It’s that time of year again when AQA Core Maths teachers get hold of the preliminary material  on which some of the exam questions (roughly 25% in recent years) will be based. There is the following warning on the front:

This Preliminary Material is to be seen by teachers and candidates only, for use during preparation for the examination on Wednesday 13 May 2020. It cannot be used by anyone else for any other purpose, other than as stated in the instructions issued, until after the examination date has passed.
It must not be provided to third parties.

It’s a pretty strong warning but, last year, I phoned AQA and asked about this. They were very helpful and after the conversation, sent me this clarifying email:

Thank you for your recent call regarding the preliminary material for our Level 3 Mathematical Studies.

I can confirm that you may not publicly share the document containing the preliminary material in any form. However you are free to create and share ideas of questions relating to the material, and to suggest possible resources that you feel might be useful for preparing students based on the material, and we would even encourage this kind of action. – Customer Services Adviser, Teacher Services AQA

So, I can’t post the preliminary material on here and all of the following thoughts and questions are based on you having access to it. If you don’t yet, it might be worth holding off on reading this post until you’ve had a chance to see it yourself.

Paper 1

Income Tax and National Insurance

This makes a welcome return with nice, straightforward tables. They are in the same format as last year so shouldn’t throw up any major surprises.

Exchange rates

These are there and it’s a very simple table. My initial feeling is that there may well be some involvement of additional charges and perhaps travelling to multiple countries.

Tennis

 

Well, I have to say this is much more open (pun intended) than last year’s material. There’s plenty of scope for some Fermi estimation here and my early thoughts are that it could be something to do with:

  • Tickets sale revenue
  • Revenue from food and drink (but particularly Pimm’s (£8.50), scones (can’t find this) and strawberries (£2.50))
  • Revenue from merchandise
  • Charity money raised (from resold tickets and used tennis balls)

A super rough guess of a question would be “Estimate the revenue taken from sales of strawberries and cream over the course of the Wimbledon Tennis Championships this July.”

For this part of the material, I think I will make use of Tom Rainbow’s suggestion of just showing students the material a bit at a time. I’ll just show the picture first and ask what they think it might be about. Then I’ll reveal a sentence or paragraph at a time and get them to mindmap their thoughts as we go. I’ll let you know how that goes.

Some links that might be useful:

Wimbledon’s own website which has an FAQ, Facts and Figures section. For example, Centre court has 14,979 seats while Court No 1 has (the super-pleasing) capacity of 12,345 seats. The food section isn’t particularly helpful though. The Facts and Figures link is one I can see myself spending a lot of time looking at over the next few weeks.

So just how much are strawberries and cream at Wimbledon 2019? Metro 2019

Facilities Management Catering are the official caterers for Wimbledon and the link gives you information on quantities used.

Wikipedia (I know you could find this yourself but it’s got a lot of background in there and I have never really been that interested in Wimbledon.)

Paper 2

Spending Habits

Last year, I found the paper 2 preliminary material much harder to get into and it’s the same feeling this year! I’m going to need some help on this one.

The full ONS report is here and the Guardian article is here.

I honestly don’t have much to say about this at the moment (sorry, I assume that’s probably why you’re here) but I hope there’s some value in knowing that someone else is a bit lost with this if that’s the way you’re feeling too. Still, I do have a couple of comments…

The graphs aren’t terrible so I expect there not to be much of the criticise the graphs types task.

The use of the average spend is weird. Let’s say you added up all the amounts that boys spent on mobile phone downloads and then found the mean average to say that “Boys spend an average of £1.25 per week on downloads” (I made that up) it’s a bit bizarre because presumably all the ones that spend £0 are dragging the average down. It’s almost as if some sort of measure of spread or confidence interval would be useful…

Houses

The original briefing note seems to have been reproduced in full in the preliminary material so a link isn’t much help.

I find this material genuinely overwhelming and will need to re-read it many times. I assume my students will need to do that even more so. I think this whole preliminary material needs to be significantly broken down and fed out to my students in small pieces.

A couple of super quick thoughts:

Why does the first bullet point pick that specific age?

The third bullet point has a statement that could be verified.

What next?

Well, I’ll re-read it and think some more.

After that, I’ll be logging onto  the AMSP Core Maths Pre-release Webinar on Thursday and will hopefully have a chance to talk to you there.

After that, hopefully I’ll be able to post some resources based on discussions I’ve had with various people.

Do let me know your thoughts!
