Modeling and Counting 10
In this video, we will learn how to
represent one object by another to help us count 10 objects. When we’re counting groups of
objects, it’s easy to lose our place. One, two, three, four, five,
six. Oh dear, I’ve forgotten which ones
I’ve counted. Can you think of a better way to
count the dinosaurs? A way to make counting easier would
be to place the dinosaurs in a line. This makes it much easier to keep
track of which dinosaur we’ve counted. One, two, three, four, five, six,
seven, eight, nine, 10.
We can also use maths equipment to
help us, like counters or blocks. Each time we count a dinosaur, we
can place a counter. One, two, three, four, five, six,
seven, eight, nine, 10. We used a counter to represent each
dinosaur. This makes counting a lot
easier. In this video, we’re going to learn
how to use equipment, like counters or blocks, to help us count 10 objects. Let’s practice counting with some
questions.
Count the rats. Find a piece of cheese for every
rat.
In this question, we’re shown some
rats. And we’re asked to find a piece of
cheese for every rat. This question is asking us to match
the number of rats with the same number of pieces of cheese. First, we’re going to need to count
the number of rats. One, two, three, four, five, six,
seven, eight, nine, 10. If there are 10 rats, then we need
10 pieces of cheese.
Which of our three groups have 10
pieces of cheese? To help us find a piece of cheese
for each rat, we could place the rats in a line. Then, we can try and match a piece
of cheese to each rat. Let’s start with the first
group. One, two, three, four, five, six,
seven, eight. We don’t have a piece of cheese for
every rat.
Let’s try the second group. If we give a piece of cheese to
each rat like before, we can see that there are not enough pieces in this group. One rat doesn’t have a piece of
cheese. If there are 10 rats and one rat
doesn’t have a piece of cheese, how many pieces of cheese are there? One less than 10 is nine.
We’re looking for 10 pieces of
cheese because there are 10 rats. So, this must be the group that has
10 pieces of cheese. Let’s check. One, two, three, four, five, six,
seven, eight, nine, 10. This is the group that has 10
pieces of cheese. We found a piece of cheese for
every rat. There are 10 rats and 10 pieces of
cheese.
Count the oranges. Color a square as you count each
orange.
In this question, we’re shown a
group of oranges. We’re told that we have to count
them. And as we count each orange, we
have to color a square. Once we’ve counted the oranges and
colored the squares here, then we can select the picture which shows the same number
of squares that we’ve colored.
So, let’s count the oranges and
each time we count, color a square. Here’s one orange, so we needed to
color one square. Two oranges, we’ve colored two
squares, three, four, five, six, seven, eight, nine, 10. We counted 10 oranges and we
colored 10 squares.
Which of the pictures shows 10
squares? It’s this one. All of the squares are colored. It shows 10 squares to represent
our 10 oranges.
Count the hats. Use the counters to show how many
hats there are.
In this question, we’re given a
picture of some hats. And we’re told that we have to use
counters to show how many hats there are. We have to select the group of
counters that has the same number as the number of hats. Let’s start by counting the
hats. Let’s use a counter each time we
count a hat. One, two, three, four, five, six,
seven, eight, nine, 10.
Which of our groups has 10
counters? We know there are 10 hats, so we
need the group with 10 counters. Does this group have 10
counters? One, two, three, four, five, six,
seven, eight, nine, 10. Each hat has a counter. This is the correct group of
counters. It shows how many hats there
are. There are 10 counters and 10
hats.
Count the snowmen in the
picture. Use blocks to show how many there
are.
In this question, we’re shown a
group of snowmen. We’re asked to count the snowmen
and then use blocks to show how many there are. In this question, we’re asked to
pick the group of blocks which has the same number as the number of snowmen. Each time we count a snowman, we
could place a block.
One, two, three, four, five, six,
seven, eight, nine, 10. We counted 10 snowmen and we used a
block to show each snowman. We have 10 snowmen and 10
blocks. Which of our three pictures shows
10 blocks? It’s this one. It has 10 blocks. We counted the snowmen in the
picture and used blocks to show how many there are. There are 10 snowmen.
Count the presents. Put counters into a ten frame as
you count.
We’re shown a group of
presents. And we’re told we have to count
them. We’re also told to put counters
into a ten frame as we count the presents. Here’s our ten frame. Let’s count. One, two, three, four, five, six,
seven, eight, nine, 10. We counted the presents and put a
counter into the ten frame as we counted. Our ten frame is full. It has 10 counters.
Which of our three ten frames shows
10 counters? It’s this one. This ten frame is full. That means it contains 10
counters. We counted the presents and put
counters into a ten frame as we counted. There are 10 presents and 10
counters.
What have we learned in this
video? We’ve learned how to represent one
object by another to help us count 10 objects.
