What to look at when you are ringing

This morning was the first session of a Plain Bob Doubles course in East Dorset. There are 4 learners, and all of them came along, already able to manage a plain course on the Two. This was a nice surprise – it isn’t usual for the course to have such advanced trainees!

The trainer advised one of the learners not to look at the floor, and a short discussion followed. I want to take the opportunity to expand on that a bit more.

Look at the rope you are following

You will usually be advised to look at the person you are following. This enables you to strike nicely. The rope moves, and after the correctly-judged interval, your rope moves. Bingo, a perfectly spaced pair of blows.

My own experience

When I learned to ring, I was only really comfortable looking at the floor. When I tried to look at people’s faces, I felt overwhelmed by the sheet quantity of information and it was hugely distracting. I was struggling to learn my first method (as I have struggled with almost every facet of learning to ring as an adult) and when I looked up, my striking worsened. The fact was, I was happier ringing wholly by ear, and I didn’t want to look around.

However, not wanting to annoy my Tower Captain, I made a huge effort to look around more. I gradually got used to it, and found it less distracting, and more helpful.

I settled for a compromise – if I am confident in the method, I look just above the head of the person I am following. This lets me see the rope, Sally and hands as they move. If I get a bit lost, I look at the conductor and try to assume a puzzled expression, hoping for a word from the wise! If I notice someone is lost and I know they should follow me, I do the head wave to catch their eye. This discipline has enabled me to develop proper rope-sight – an impossible challenge if you don’t ever look at the ropes! The benefit of having rope-sight is that I can make adjustments if the bell in front of me is fractionally early or late. This smooths out any small errors and is good team playing.

Don’t Look Up

Actually, none of the ringers in this group were looking up, but many people do in the early stages. It is risky (something could easily fall through the hole and get in your eye), and it isn’t providing you with any useful information apart from the path of the Sally. If a learner is looking up, it usually means they are anxious about missing the Sally, so they probably wouldn’t be attempting Bob Doubles in any case.

Don’t Look Down**

If you gaze at the floor, you will miss all the useful hints people may give you that will help to put you back in the right place if you are a little bit lost. It’s fine later on when you are more experienced, but at the moment, when you are likely to make the odd method mistake, an occasional wink or a wave is a lifesaver! Of course you could be corrected verbally, but this distracts the other ringers (who have to listen out in case the correction is aimed at them) and it can be surprisingly hard to hear what is being said, over the sound of the bells. So the gold standard for a bit of correction is to receive it visually, and you need to be looking at the person giving it.

** When you CAN look down

You may notice plenty of experienced ringers who appear to be gazing at the floor. The whole band is absolutely confident of the method, and so they are ringing correctly at every blow. They don’t need any winks or waves, so they are listening to the striking and aiming to make it as perfect as they can. However, I would bet that 90% of them are, in reality, looking really carefully at the movement of the other ropes. They are using peripheral vision and can process the movement of a group of ropes at the same time. They are picking up lots of useful information from what they are seeing, and many of them will look up if they hear a mistake, and offer some correction. If you want to build this skill, practice using your peripheral vision when you are not ringing.

Ringing blindfold

I had to throw in this video for your entertainment! Please read the disclaimers at the start – pretty much “don’t try this at home”.

You may be surprised that the ringing starts with more than 2 minutes of rounds, as the band acclimatise to ringing without ropesight and the inevitable errors that creates. The rounds are a bit wobbly at the start, but after a while they iron out the striking until it is good enough to start the method. Thereafter the ringing is, whilst not up to that band’s usual standard, excellent by the standard of 95% of bands.

Funny Bob Doubles Made Easy

This excellent method is recommended by the association of ringing teachers (ART). If you want to download a complete explanation of the method, head to https://ringingteachers.org/application/files/8316/1426/5228/Funny_Bob_Doubles.pdf

Here are all the lines written out seperately:

Before you start:

You will need to be confident ringing Plain Hunt from several different bells.

To help you learn it, practice writing your chosen bell out onto blank dot paper. Here is a blank dot paper suitable for Funny Bob Doubles:

Brilliant (free) Factors and Multiples game on NRICH website

I am having a bit of a craze on Factors at the moment. I searched the web for “Fun with Factors” and came across this brilliant and very simple game on the NRICH website.**

There’s a neat online version or you can play a pen and paper version. I am likely to spend a while playing the online version today! What’s the longest chain you can make? I managed 18.

If you are aiming for a depth of understanding of Factors, then play as many games as possible – this is a really simple game for 2+ players that just needs 2 dice and a CASIO scientific calculator.

If you know another great factorising game, put it in the comments below!

**The game works brilliantly on a laptop but not so strong on an android phone.

How to find all the factors of a number using a Casio scientific calculator

I had an email from B. this morning. He is helping his granddaughter with her Maths and things have changed a bit since he was at school! (I can relate to that too). He said:

“Can the factors of a number (360) be found by using a casio calculator fx -85GTX? Ans: 1, 360, 2, 180, 3, 120 etc”

The answer is yes.

Method using an FX-83GT PLUS
Method using an FX-83GT X Classwiz

Tip for clever clogs… if you “end” your table with the square root of the number (in this case, √360), you won’t get any repeats, and you can be confident you have found all possible factors!

Angles in a Regular Polygon

You can find the Exterior angle in a regular polygon by using Ratio Grids if you want to.

Video Example – finding the number of sides of a polygon given the exterior angle

Percentages Using Ratio Grids

If you are not already confident using RATIO GRIDS then watch this video first!

What is 35% of £14?

What is 15% of £85?

My savings target is £5500. I have saved £2640. What percentage have I saved?

Jo scored 65% in a test. She scored 26 marks. What was the test marked out of?

A tree was 15m tall in January. Now it is 18m tall. What is the percentage increase in height?

Another tree has grown 15% since January. It is now 46m high. What was its height in January?

Now try some problems yourself:

Currency Conversion using Ratio Grids

Check out the Introduction to Ratio Grids if you are not already an expert!

When you are asked to do a currency conversion, you will usually be given an exchange rate first, as in this question:

“George changes some pounds into Euros. The exchange rate is £1=€1.18. If he changes £350 into Euros, how many Euros will he receive?”

Draw a simple Ratio Grid and give headings of £ and €. Put the numbers 1 and 1.18 in the correct columns. Then, the final number from the question, £350, goes in the £ column under the 1. Putting the numbers into their correct places is easy if you have headings! Put a ring around the empty space – that is where your answer will go.

In this grid, the 2 multiplying numbers are the “1.18” and the “350”, and you will divide by 1. So the sum will be 1.18×350÷1.

The answer is 413, and it is clearly in the Euros column, so give your answer as €413.

It’s easy if you get the headings right!

If you want lots of practice, Mr Corbett has a great set of currency conversion questions.

Exam-style questions are here** and the answers are here. (Mr Corbett doesn’t use Ratio Grids so his methods won’t look the same, but the answers are all the same, obviously!)

** Some of these questions are really challening – they may require 2 ratio grids, so think carefully! If an exchange rate changes, you will need a new grid for the new rate.
