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.
