Math For Dyslexic People And People With Dyscalculia - Rounding Maths Lesson
Narrated By Jodie Turner
Produced By Ashley Gaynor (aka Ash The Great)
A Word From Jodie The Narrator
I had to do over 300 takes to complete this video. There were many times when we had to record the narration one line at a time because I would mess it up. I am very dyslexic and reading aloud from a script is still very difficult. Nevertheless, if I let difficulties and hurdles stop me, then I would have spent my entire life stood still.
A Word From Ashley The Producer
Most people are completely unaware of just how many facets dyslexia and dyscalculia have. Sometimes, dyslexia presents almost as a personality disorder or a serious learning disorder. If you live with somebody with dyslexia or dyscalculia, then give them the benefit of the doubt now and again. There are times when his or her dyslexia will present almost like a borderline personality disorder, and try to remember that a dyslexic person’s performance will vary wildly from day to day.
The Script For The Rounding Maths Lesson
0001 - 0010
Rounding up is not just something that my ass is doing. Rounding up is also a way of making numbers whole.
0011 - 0016
Before we start, take a look at this and I will explain it later. Here are the numbers 0 to 9. If you are rounding and the number is between 0 and 4, then the rounded number stays the same. If the number is between 5 and 9, then the rounded number goes up by one. You don’t have to understand that yet because I will explain it later.
We round numbers to make life a little easier.
0018 - 0026
Instead of saying I had one million three hundred twenty-one thousand and eleven views, you round it up and say I had approximately one million views.
0027 - 0031
0032 - 0039
Let’s start with money. Here is £1.32. Let’s round it to the nearest pound. To make it easier, let’s draw a box around the number we are going to round. In this case, the number we are going to round is the number one.
0040 - 0044
Look at the number to the right of it, and recall what I told you earlier. Ask yourself if the number to the right is between 0 and 4 or between 5 and 9.
0045 - 0048
If it is between 0 and 4, then the number you are rounding stays the same, and if it is between 5 and 9, then the number you are rounding goes up by one.
0049 - 0053
In this case, we are rounding this number.
0054 - 0057
The number to its immediate right is between 0 and 4, so the number we are rounding…
0058 - 0059
0060 - 0061
…remains the same.
The number in the box will stay the same. The number one.
0063 - 0064
Did you know there are one billion people in china?
0065 - 0073
That means that if you are a one in a million, there are still one thousand people in your country who are just as good.
The final stage is to turn the remaining numbers to zero.
0075 - 0084
That means that these numbers to the right of the box must now become zeros.
We are left with just one pound.
Wow. That was easier than…
…after two shots of vodka.
0089 - 0091
Rounding £1.32 to the nearest pound will give you one pound.
Why do I keep saying let’s “Round” numbers rather than round up numbers?
0093 - 0100
I say it because calling it “rounding up” is a little confusing. After all, if the number is between 0 and 4, then we round down…we do not round up. Half the time, when people ask you to round something up, you end up rounding it down. I just find it a little confusing, so I refer to it as “Rounding” numbers rather than rounding up numbers...Let’s run few a few more rounding examples.
[repeat the video section between frames 0045 and 0048]
We have the number one thousand and forty one. It can be written this way.
Or this way
Or this way
And so forth
0108 - 0109
They all mean the same thing, so let’s stick with this version for now. I want to round this number to the nearest ten, which is this number because they go.
The four is one of the tens, and I want to round it to the nearest ten.
To make things easier, I put a box around the number I am going to round.
0116 - 0133
Look at the number to the right of it. It is a number one, which means the number in the box should stay…as the number four... The only thing left to do is to turn the number one into zero.
0134 - 0136
1041 rounds to 1040.
[Insert video but speed it up to make it shorter]
The process we have just undertaken is called rounding up, but in this case we rounded the number down from 1041 to 1040. That is why I say that calling the process rounding up is confusing.
0137-01 - 0137-02
Let’s recap a few of the principles. Pick a number you are going to round and put a box around it. In this case we are rounding to the nearest ten, so we put a box around the five. Putting a box around it makes rounding a little easier. Your job is to decide if the number in the box should remain the same or go up by one.
0137-03 - 0137-06
Your job is to decide if the number in this box
Is going to remain the same or go up by one.
0137-08 - 0137-12
To decide, we use the number to its immediate right.
We decide by using this.
0137-14 - 0137-16
This is in the red category, which means the number in the box has to go up by one.
0137-17 - 0137- 21
The number in the box goes up by one and you have rounded your number.
0137-22 - 0137-31
Once the rounding is done, all the numbers to the right of the box must become zeros. That is the last thing you need to do when you are rounding numbers. Once you have decided what you are going to do with the number in the box, you must convert the numbers to the right into zeros. …..Now, let’s get back to some more examples.
If we wish to round the number 1041 to the nearest….
Thousand. Then we should put a box around the number one in this case.
0140 - 0148
With our box around the number we are going to round, we look to the right to see a zero. The zero is between 0 and 4, which indicates to us that the number we are rounding should stay the same.
0149 - 0156
Next, we turn the numbers to the right into zeros.
If we round….
0158 - 0160
1041 to the nearest thousand, then it becomes 1000
Fancy doing some more?
0162 - 0164
[in low, sexy voice]

0166 - 0171
Three hundred and seventy seven. Let’s round this number to the nearest hundred. That means we put a box around the hundred and look at the number to its immediate right.
0172 - 0174
The number is between 5 and 9, so we have to round the number up. The number in the box needs to round up from…
0177 - 0188
Now we have done that, we need to look to the right of the box again. Now that we have rounded the number in the box, we need to look at all the numbers to the right of the box. They all need to become zero.
0189 - 0191
When we round the number 377 to the nearest hundred, we get 400. We have rounded the number up to 400.
Let’s do a final one where we round a number to create a whole number. This is the final one because my girlfriend says I go on too long and I do not want to take up too much of your time. She said it in the winter of 2013. I was a rosy cheeked fella and she was a pale skinned runway model. She had ezema, which made stroking her skin tricky, but I was brought up to take the rough with the smooth…anyway, I digress. My girlfriend says I go on too long… She is both right…and imaginary.
[Changing the subject humorously]
A whole number!!!!!
…..This isn’t one of them.
A whole number doesn’t have decimal numbers in it, unless the decimal numbers are all zeros. This number has five seven five in it. I am going to use the power of rounding to create a whole number and get rid of those decimal numbers.
To make this a whole number, I have to do some rounding. To make a whole number, we need to round the number just before the decimal point. Here I have placed a box around that number.
0195 - 0201
The number to the right of the box is a five. This means the number we are rounding is going up by one. It is going up from a number two to a number three. Now the rounding is done, we need to create some zeros.
0202 - 0215
All of these need to become zero.
And there we have it. We have made the number 42.575 into a whole number. You can write your 43 to three decimal places such as in this image.
Or, you may choose to remove the decimal places and simply have the number 43. You can write it as you wish because they both mean the same thing because they both have the same value. If you are doing a math exam, then write it to whatever decimal place your math test tells you to. In other words, write it the way it is written in your exam question.
0218 - 0220
We have rounded 42.575 to create a whole number. This turned our 42.575 in to 43.
Seek out a few more examples and train yourself to help you become an expert at rounding. Look over this video again right now, and again in about a week and see how much you remember. Notice…how when you watch it again you are a little less frustrated and are somehow able to re-grasp it a little quicker than when you first watched the video.
Remember that with dyslexia and dyscalcia, you are going to have good days and bad days. Re-watch it again right away, and try the video again another day. If you don’t get it right away, then you are probably just having a bad day. Move on and re-try the video another day. You will get there eventually.
This video was narrated by Jodie Turner, who is utterly dyslexic. That is why the audio for this video sounds a little odd in places because we had to do over 300 takes and cut it together to get it right. Here are two of our favourite bloopers that she did.
