Writing Numbers up to 10 in Words

In this video, we’re going to learn how to write numbers up to 10 in digits and in words.

When we’re learning about numbers, it can be helpful for us to represent them in different ways. We can write them using digits. We can show them as pictures. We could model them using maths equipment. And then we can also write them as words. And it’s this final way of showing numbers that we’re going to be thinking about particularly in this video.

Now do you know how to write and how to spell the numbers up to 10. The number 1 has three letters. And although when we say it, it makes a “wuh” sound at the start, it doesn’t begin with a W. We spell 1 O-N-E. After 1 comes 2. There’s more than one word that sounds like 2. I’m going to the park, or that jumper is too big. But when we write the number 2, we spell it T-W-O. After 2 comes 3, which begins with a “th” sound. Do you remember what letters make a “th” sound? The letters T followed by an H make a “th” sound. So the number 3 begins with the same letter as the number 2. We spell 3 T-H-R and then two Es on the end: three.

1, 2, 3, 4. This is the first of two numbers that begins with the letter F: F-O-U-R, four. The number 5 begins with the letter F too. We write 5 as a word: F-I-V-E, five. After 5 comes 6. This is a three-letter word: S-I and then an X on the end, six. 7, and we spell this word S-E-V-E-N, seven. And out of all the numbers up to 10 probably the trickiest to spell is the number 8. It’s got some interesting letters in there. The number 8 begins with an E: E-I-G, which is a silent letter, -H-T, E-I-G-H-T, eight. Then comes the number 9, which we write as a word as N-I-N-E, nine. And then, finally the number 10, which is a nice easy one to spell: T-E-N, ten.

So although this is a maths video not a spelling video, it is important that we know how to write these numbers as words. Because if we ever see these numbers written as words in questions, we’ll know what they’re talking about. Now possibly the best thing we can do to learn how to read and write numbers in words is just to keep practice doing it. So let’s start by trying some activities and puzzles just to keep us practicing.

First, we’re going to get rid of all the digits. Now you’re going to see a robot appear on the screen pointing to different numbers. Can you read them? This is number 4, 7, 10, and number 1.

Now at the bottom of the screen, we can see another robot holding a balloon. Can you now see a digit on the balloon? Which word represents this number? Can you match it? Well, we know that this digit represents the number 5. And when we’re looking for a word that represents the number 5, we’re looking for a word that begins with the letter F. Can you see it? Here it is at the top. Let’s try another one. Where can we see the word that represents this number? Well, we know that this digit represents the number 8. Now do you remember how to write the word 8? E-I-G-H-T.

Here’s a puzzle for you. Here we’ve got four different numbers. But what letter of the alphabet do these four numbers have in common? Let’s write them as words to find out. First, we’ve got the number 9. Do you remember how to write the number 9? N-I-N-E. Next, we’ve got the number 8: E-I-G-H-T. Now if we look closely at our first two numbers, there are two letters they have in common. Can you see they both contain the letter I? But they also both contain the letter E. I wonder which of these letters all of our numbers have in common.

Next comes the number 6. We write this as a word, S-I-X, and then finally the number 5. We write this as a word: F-I-V-E. This is another word with both an E and an I in it, isn’t it? But can you see which one letter all of our numbers have in common? It’s the letter I! Do you know? I’ve only just noticed this while making this video, but the letter I is in the same position in all these numbers too. Perhaps this might help us remember how to spell them.

Let’s try one more puzzle. Here are all the numbers from 1 to 10. Now when we’re writing these numbers as words, only one of the numbers has the same number of letters as the number it represents. Which one is it?

Now do you understand what we’re asking here? For example, this is the number 5. And we write the number 5 F-I-V-E. So the number 5 has four letters. We’re looking for a number that has the same number of letters as the number itself. Do we write the number 1 using one letter? Of course, we don’t. We write it using three letters. It’s not the number 7. There are five letters in the word seven. And we know it can’t be 9 or 10 because they’d be really long words to spell.

We write the number 3 using five letters, and also for the number 8. But we spell 4 F-O-U-R. The number 4 is the only number between 1 and 10 that has the same number of letters as the number itself.

Now hopefully by trying these different fun puzzles and challenges, we’ve practiced reading and writing the numbers up to 10 in words.

Let’s see how much we’ve learned now by asking some questions where we need to do this.

How many trees are there? Write the answer in words.

We’re given a picture of some trees to look at. And we know we need to count them because we’re asked how many trees are there. Let’s get counting: 1, 2, 3, 4, 5. We counted 5 trees. Now often when we’re writing the answer to a maths question, we might write the number 5 like this. This is writing it as a number using a digit. But in this question, we’re told that we need to write the answer in words. In other words, we need to use letters to spell out the word 5.

Do you remember how to write 5: F-I-V-E. And you know both this and this mean exactly the same thing. They’re just different ways of representing the number 5. We’ve counted the number of trees, and we’ve written our answer as a word. There are five trees.

Choose the model that represents this number.

In this question, we’re given a number. But did you notice we didn’t read it out when we read out the question? This is because it’s good practice to get you to have a go. What number does this word represent? It’s spelt N-I-N-E. It rhymes with line, spine, shine. Of course, it’s the number 9. We can represent the number nine as a word like this, also using digits. We know how to write the number 9 like this too. But another way we can represent the number 9 is by using a model.

Now here we’ve got some 10 frames to look at. Which one represents the number 9? Our first 10 frame shows one, two, three, four, five. This is not the number we’re looking for. And if we look at our second 10 frame, we can see it’s completely filled with counters. And we know what a full 10 frame represents. It’s the number ten. We can see how many counters are in our next 10 frame without really counting them, can’t we? This shows the number two.

There are quite a few in the next 10 frame. So let’s count them: one, two, three, four, five, six, seven, eight, nine. We knew that the word in the question represented the number 9. And so the correct model is the one that contains 9 counters.

Complete the following pattern: five, what, what, eight.

Now it might be easy to look at this question and think to yourself, “I can’t see any numbers there. It’s all just words.” But you know some of the words in this question are numbers. Did you notice as we read out the pattern, 5 and then 8 at the end? But we’ve got two missing numbers in between. What numbers might come in between five and eight?

What if we were counting in ones? 1, 2, 3, 4, and now we get to our pattern, 5, 6, 7. And then we get to our final number 8. So what do you think? Should we just write the numbers 6 and 7 as our missing numbers, 5, 6, 7, 8? The pattern doesn’t look quite right, does it? These are the correct missing numbers, but we need to represent them in a different way. As we’ve tried to answer the question, we’ve represented the pattern using models, using digits, but the numbers in the pattern itself are written in words. We’re going to have to write the numbers 6 and 7 as words.

We write the number 6 S-I-X and the number 7 S-E-V-E-N. The missing numbers in our pattern are six and seven.

Now what have we learned in this video? We’ve learned how to write the numbers up to 10 in digits and also using words.
