289. The secret formula for success

You may remember this advert for Frosties cereal (US Frosted Flakes) from your childhood. If you do you’ve been around as long as me:

What was Tony’s secret formula? We never found out!

Enough reminiscing I hear you cry! How does this help anyone?

Well, in the new GCSE exam specifications the formulae sheets have gone. Specific formulae may be given in an individual question, but due to the lack of a working crystal ball we don’t know the frequency with which this will happen. To help with this I have typed up the Edexcel formulae into a PowerPoint. You can print it out and put it around the room, you could have a formula of the week, you could leave a slideshow running while students work, you could even print it small on card and make a pack of flashcards. Mine are laminated and hanging from a washing line, I’m going to move them around so that students have a varied view.

Whatever you do, increased familiarity improves retention – just think back to the posters you regularly saw as a child. I have made different versions for different situations – Edexcel vs no exam board, white background vs pale blue background, pdf vs pptx. Download whichever version you need:

279. Old GCSE vs new GCSE in English: a Rough Guide

My previous infographic blog post comparing the old and new GCSE Maths was rather popular. I had requests for an English version, but I’m no English teacher. However, I’ve worked with Mr S (an English teacher at my school) to create this infographic:

This infographic specifically works for the change from WJEC to AQA English. There is also a general version of it, should it be of use for other exam boards. Download the pdfs below or click on the images for the jpegs.

278. Rough Guide to GCSE Maths (new syllabus vs old syllabus)

I mentioned on Twitter that I’d made an infographic for students to help explain the changes to the GCSE Maths curriculum. Several people expressed an interest in it, so here it is:

GCSE infographic general

There are two versions – one which specifies Edexcel and one which does not specify an exam board. We use Edexcel, but the general version would work for other boards..

I must stress that these are rough guides and are not endorsed by any exam board – I created them to help my students understand the big picture. I printed them A5 size to fit in exercise books and A4 to go on the wall. A big thank you to Mrs D for proofreading/checking it.

Update: I will be editing these files to clarify the Good Pass jigsaw piece. A good pass is a Grade 5, the Grade 4 refers to the funding rules for College/Year 12 resits

260. Filter Maths

There is a moment of satisfaction to be had when the last drip of filter coffee drops into the jug: a lovely aroma of fresh coffee and the anticipation of a well-earned drink.

Don’t worry, the ‘Sandpit’ hasn’t gone all hipster foodie overnight! The slow drip of coffee leading to a rewarding cup matches perfectly with the slow drip of revision, leading to a rewarding grade.

The exam season is fast approaching and the photocopiers are starting to crank out past papers. You start handing out papers and expect them to hand them in …

That’s the point it starts to go wrong:

  • They don’t hand them in.
  • They give up halfway through.
  • They skip pages and it takes you ages to find what they’ve done.
  • They lose confidence.
  • If you issue A5 size booklets they lose them.
  • If you issue A4 size booklets, they complain and the booklets get mangled.
  • You get frustrated – don’t they realise it’s for their own good!

This year, why not try out this idea instead:

  • Hand out the exam board formulae sheet.
  • Hand out the grade boundaries.
  • Hand out the first four pages reduced to A4, back to back.
  • Collect in the first sheet.
  • Repeat for the next four pages.
  • Collect in the second sheet.
  • Repeat until the questions start getting harder, then decrease it to two pages back to back.
  • Continue until the paper is finished.

This is time-consuming and it is best started well in advance of the main revision period, but it works. The individual sheets have a manageable amount of content and are less intimidating – they also weigh a lot less than 33 exam papers. As a teacher, you get a clear picture of which areas to revisit as the topic list is short. Each student keeps a running total of how they are doing on the paper. The grade boundaries sheet lets them keep track of their progress towards their target grade.

The consequence of doing this process with a couple of papers is that students feel more confident approaching papers. They will start to notice themes in the wording and topics. They will also realise that it’s important to ‘bank’ as many marks as they can in the first half of an exam paper.

My class responded well to this drip-feed of questions. After the first sheet they felt proud of themselves when they realised they’d achieved a grade D in just four pages of a Higher paper and were calculating how many marks they’d need for a C. The number of late homeworks dramatically dropped and the effort level went up.

This idea is simple and non-subject specific. It would work equally well with physics, chemistry, biology … in fact any paper which has a fair number of questions.

Good luck with the revision!

 

 

200. Website/Resource of the week 4

Wow! This is proper blog post number 200. How should I mark this occasion? Why, by recommending another splendid site of course!

To quote the folks themselves: JustMaths is born from the passion and spirit of three full time teachers at the “most improved school in England” (January 2013).

The site has both free and subscription resources. The latest initiative is the ‘Bread & Butter’ worksheets. It consists of straight-forward starter worksheets to practice essential skills for students: Just Maths: Bread & Butter. My class use them every lesson and I’ve noticed a real improvement in their confidence and quality of solutions in just two weeks.

188. Ducks, chalk and gravity

So how did TeachMeet result in me standing in a supermarket one evening doing a price comparison of duct tape?

Let us go back in time to #mathsmeetnorthwest. Dave Usher did a brilliant presentation on ‘Big Maths’, including the use of gaffer (duct) tape in lessons. I thought this was a genius idea – sticky, sturdy and temporary. I didn’t get a chance to buy any at the weekend, so I ended up in the supermarket on a weeknight.

But what to buy?

Cheap own brand duct tape at £2.95 for 15m or branded ‘Duck’ tape at £3.95 for 25m?

I started school the next day with one idea on how to use it, which quickly developed into three..

Lesson 1: Averages

Equipment: Duct tape, liquid chalk marker

I did averages and range indoors. This meant I couldn’t chalk the walls or floor. However I could mark out key features with tape. I used the activity Averages and marked out the median, the highest and lowest values on the floor. It was at this point I figured out I could write on black duct tape with liquid chalk marker – brilliant! We labelled the wall with the highest and lowest heights of the class so we could see the actual range of heights.

Lesson 2: GCSE Revision

Equipment: Exam papers, scissors, glue, wall paper, duct tape

I have been using the Foundation GCSE Review with my Higher GCSE resit group. Reviewing ten Higher GCSE papers involves over 200 questions – that’s a big wall display! Both of the TeachMeets I have attended have used the idea of learning wallpaper. So that’s what we used – I’m grateful that some of my students are over 6ft tall or the wall display wouldn’t have gone up.

Now the duct tape was used to secure the top of the wall display and to ‘passer-by’ proof the bottom. It should last longer now that the lower end is reinforced.

Lesson 3: A-Level Mechanics

Equipment: Duct tape, liquid chalk, mobile phones, calculators, soft ball (I used a ball of wool)

It’s all very well drawing diagrams for A-Level Mechanics questions, but how about a life size diagram? We were looking at vertical motion under freefall/gravity. I gave the students pieces of duct tape chalk labelled with a, s, u, v, t. We went to the staircase and labelled the wall with the tape – so u (initial velocity) was taped to the top of the bannister and v (final velocity) went on the floor at the bottom of the stairs, etc.

image

The students then labelled what they knew: a=g, u=0, v=?, t=?, s=?

The students used mobile phones to time the drop from the bannister to the floor and calculated the distance and final velocity. The physical activity allowed us to think about how to draw these kinds of diagram.

And finally …
Just some pictures of an alternative whiteboard:

149. Cold Questioning

Cold calling is the infuriating practice of randomly contacting people in order to sell something that they don’t want and didn’t ask for. Don’t ask me for my opinion on this business idea!

image

Cold questioning is the practice of putting a random question on the board and asking pupils to solve it.

Example: GCSE revision
I have a class of critical C/D students who are sitting their GCSE in November. We have been revising prime factorisation, indices, simplifying, standard form and HCF/LCM. Today I put this question on the board:

A pair of trainers are reduced by 30%. The sale cost is £75, how much were they originally, to the nearest £1?

I was pleased to see them talk about the problem and have a go.

Students were randomly selected to share their answers and only two answers occurred – both of them wrong, but with a hint of understanding. Answer A resulted from calculating 30% of £75 and adding it on. Answer B resulted from subtracting the 30% from £75.

Now this isn’t as depressing as you may think, because as we discussed this it became evident that the class were confident calculating simple percentages – they just struggled to apply this knowledge. One student said they had used a multiplier. This opened up the task as we developed the link between reverse percentages and multipliers. Some of the class weren’t convinced, so we had a quick ‘converting percentages to multipliers, including inc/dec’ quiz. We even extended it to fraction to decimal conversion.

Finally, we looked at rounding as it was specified in the original question.

Review
I could have prepared a step-by-step revision lesson, gently taking them through these topics. I think ‘ambushing’ the class with a topic they haven’t studied for a while was more effective as they used a variety of skills to solve the problem, rather than repeat given procedures.

Ambushing your class
*Pick a topic you haven’t looked at for a while
*Avoid easy/obvious questions
*Try to include more than one skill
*Allow sufficient thinking/discussing time
*Finish off with another question, which requires similar skills
(Eg my second question was a reverse percentage involving an increase)
