Reading and Writing Eight and Nine

In this lesson, we’ll learn how to read, write, and model the numbers eight and nine. What do the numbers eight and nine look like? We could model the number eight using a ten frame. Or we could model the number nine by shifting nine beads on a counting string. But you know, we can also write the numbers eight and nine using symbols. We call these symbols digits. When we write the number eight, we start at the top. We begin by drawing a curve that points backwards and then a curve that points forwards, just like we’re writing the letter s. Then we carry on with a curve that points backwards and another curve that points forwards, all the way back up to the top.

Can you see how the number eight looks like two circles on top of each other? We started at the top. And first, we drew a curve that pointed backwards. Then we continue to draw it downwards and drew a curve that pointed forwards. Now, we hit the bottom. And it looks like we’ve written the letter s. Now, it’s time to make our way back up again. We draw another curve that points backwards across the middle and a curve that points forwards to connect back up to the top again. This digit represents the number eight. So whenever we see this symbol, we know that it means eight. We could even label the number eight next to our ten frame. Start at the top, write a letter s, and then come across and all the way back up to the top again.

Now, what about the number nine? We can start writing the number nine at the top. But a good place to start is at the side because we’re going to start by drawing a circle. We draw a circle all the way around and then back to the side of the circle where we began. Now, we continue the line up and then down. In other words, we draw a circle and a line. A good way of remembering this is a circle and a line makes the number nine. Let’s trace our number nine.

So we start at the side. And first of all, we draw a circle, back to where we started. Now, we need to draw a straight line all the way to the top, which isn’t very far. Turn round and continue all the way to the bottom. Let’s try writing the digit nine without any dots to help us. Start at the side, draw a circle, all the way up to the top, all the way down to the bottom. And again, wherever we see this digit, we know that it represents the number nine. Let’s practise answering some questions that involve these numbers, eight and nine.

Pick the basket that has eight flowers.

This question has a digit in it. It’s the number eight. We’re asked to pick the basket that has eight flowers. And we’re given three different baskets to choose from. We need to count the flowers to find the answer to the question. How many flowers are in the first basket? We can see one, two, three, four, five, six, seven. This is too small; we’re looking for a basket with eight flowers.

How many flowers are in our second basket? One, two, three, four, five, six, seven, eight — we can see this is going to be more than eight — nine, 10. This time, we have too many flowers. We only have one more basket left to count. Hopefully, there’s going to be eight flowers in this one. One, two, three, four, five, six, seven, and a yellow one makes eight. We found the answer by counting each basket of flowers. The basket that contains eight flowers is this one.

Select a group of nine.

The pictures in this question show lots of tubs of popcorn. Our question contains a digit. And this digit represents the number nine. We need to look at each of the three groups of popcorn that we have and to select the one that is a group of nine tubs. Which group contains nine tubs of popcorn? Let’s count them. We could put a counter on each tub as we count it. This way, we know we haven’t missed any out. How many tubs are in our first group? One, two, three, four, five, six, seven, eight, nine. We found the group of nine straight away. It looks like this might be the answer we’re looking for.

Let’s count the other groups just to check. In the second group, we can count one, two, three, four, five, six, seven — only eight tubs of popcorn in the second group. And in the third group, we can count one, two, three, four, five, six, seven, eight, nine — we can see this is going to be more than nine — 10. We’ve counted all the tubs of popcorn to find the answer. The group of nine is this one.

What is the number on the domino?

Different dominoes represent different numbers. And the way they do this is by showing different numbers of dots. In the picture, we can see a domino that we’re being asked about. We’re being asked what is the number on the domino. To find out, we need to count those dots. So that we count every single dot and we don’t miss any out and we don’t count any twice, let’s put a counter on each dot to start with. We have the same number of counters as dots. So let’s move each counter one by one onto the ten frame. And as we do, we can count them.

So how many dots are there? There’s one, two, three, four, five. We know this cause we’ve filled the first line of our ten frame. Let’s keep counting, six, seven, eight. We’ve counted eight counters. So there must be eight dots. We can write the number eight using the digit eight, just like this. We found the number on the domino by counting each of the dots. We found there were eight of them. The number on the domino is eight.

Count the dogs. Write the number in digits.

In this question, we’re given a group of dogs to count. How many are there? We can see one, two, three, four, five, six, seven, eight, nine. There are nine dogs altogether. But to answer the question, we’re asked to write the number in digits. How do we write the number nine as a digit? We know that we can form the number nine by drawing a circle and then going up to draw a line all the way down. This digit represents the number of dogs that there are. We counted nine dogs, and so we recorded our answer writing the digit nine.

What have we learned in this video? Well, firstly, we’ve learned how to read, write, and model the numbers eight and nine. In particular, we now know how to write both numbers as digits.
