Counting Objects up to 10
In this video, we’re going to
practice counting up to 10 objects. And we’re going to learn that the
number of objects doesn’t change even if they’re arranged in different ways. Here are some birds. They’re standing in a line
balancing on a wire. How many birds are there? One, two, three, four, five, six,
seven. There are seven birds, and we could
represent our seven birds by using seven counters in a line.
Now, let’s imagine that the same
birds fly off making a circle shape. How many birds are there now? One, two, three, four, five, six,
seven. Even though the arrangement or the
position of the birds is different, the number is still the same. We can show seven in many different
ways. Now, let’s practice counting some
objects in different arrangements.
How many cats are there?
The cats in this problem are
standing in a line, and we’re being asked how many are there. We need to count the cats. We could use a 10-frame and
counters to help us. To start with, let’s put one
counter underneath each cat. We know we have the same number of
counters as cats. Now, let’s move each counter onto
the 10-frame. And as we do so, let’s count
them. One, two, three, four, five, six,
seven, eight, nine, 10. There are 10 counters, and our
10-frame is full. We’ve counted the number of cats
using counters. How many cats are there? There are 10 cats.
Let’s practice counting more
How many stars are found in the
flag of Singapore?
Singapore is a country, and this is
what its flag looks like. It’s made up of a moon shape or a
crescent and some stars. We’re asked, how many stars are
there? The stars are in a circle
arrangement or pattern. To help us remember which stars
we’ve counted, why don’t we draw rings around them as we say each number? We’ll start counting at the
top. One, two, three, four, five. We’ve counted five stars. The flag of Singapore shows five
The objects in our next question
make a rectangular shape, but we can still count them.
How many umbrellas are there?
To answer a question that asked us
how many, we need to count. And we’ve been given a picture of
some umbrellas to count. How could we make sure we count
each umbrella? We could start by putting a cube
next to each umbrella. There we go. There are the same number of cubes
as there are umbrellas, so all we need to do is to count the cubes. One, two, three, four — that’s the
top row done, let’s carry on counting — five, six, seven, eight.
So, we know there are eight
umbrellas. The cubes are in a tall tower and
the umbrellas are making a rectangle shape. But both arrangements show the
number eight. We can show the same number in
different ways. We’ve counted the umbrellas and we
can say there are eight.
The objects in this question were
in nice neat patterns. But what if they’re all jumbled up
and not really making a pattern at all? Can we still count them? Let’s try.
Count the jewels aloud, and then
write the number.
In the picture, we can see some
shiny jewels. Now, they’re not making a nice neat
line, but this doesn’t matter. We can still count them. In the question, we’re asked to
count the jewels aloud. And then once we finish, we need to
write the number. Let’s point to each jewel and say
each number out loud. And as you watch the video, count
aloud too. One, two, three, four, five, six,
seven. We’ve counted the jewels, and there
are seven of them.
So to answer the question, we need
to complete the second part. We need to write the number
seven. And the number seven looks like
this. We counted the jewels out loud, and
then we’ve written the number to represent how many there are. There are seven jewels.
We’ve counted objects in all sorts
of shapes. In our final example, let’s see how
we can represent the same number in different ways.
Count the red cubes. Which set of cubes has the same
number as set A?
In the first picture, we can see a
line of red cubes, and they’re labelled set A. We’re asked to count the red
cubes. How many are there? One, two, three, four, five, six,
seven. There are seven red cubes. Now, we’re given three more sets of
cubes to look at, this time they’re yellow cubes. And we’re asked, which set of cubes
has the same number as set A? Well, if we look at our cubes, they
For a start, they’re not red;
they’re yellow. And they’re not in a line. They’re all jumbled up. None of them look the same as set
A. But we know different arrangements
of objects can still show the same number. Let’s count our sets of yellow
cubes until we find one that has seven cubes just like the red. Let’s count the first set to begin
with. One, two, three, four, five, six,
seven, eight. We’re looking for a set of seven
cubes. So, this answer is not right.
Let’s count our second set. One, two, three, four, five, six,
seven. This set of cubes has the same
number as set A. Let’s count the final set just to
check. One, two, three, four, five, six,
seven — oh this is going to be more than seven — eight, nine. We counted seven red cubes. And we know that it doesn’t matter
how cubes are arranged or even what color they are. We can still show the same number
in a different way. And so, the set of yellow cubes
that has the same number as set A is the one that contains seven cubes.
Well, what have we learned in this
video? Well, firstly, we’ve learned to
count up to 10 objects. We’ve had lots of practice at doing
this. We’ve also learned that even if we
change the arrangement of the same number of objects, the number stays the same.
