Modelling and Counting One, Two,
Three.
In this video, we will learn how to
represent one object by another to help us count one, two, or three objects. Here, we have a picture of a
marble. We could use one counter to
represent the marble. Now, we have another marble. So, we need another counter. Let’s count how many counters there
are. One, two. If we have another marble, we need
another counter. How many counters do we have
now? One, two, three. There are three marbles and three
counters.
We could also use a five frame to
help us count the marbles. For every marble, we can draw a
square inside the five frame. Here is one, two, three, three
marbles and three squares in our five frame. We could also use blocks to help us
count. There are three blocks and three
marbles. We used a block to represent each
of the marbles. One, two, three. We can use objects and models to
make sure that we count correctly. Let’s practice using models to help
us count with some examples.
Use counters to show how many
oranges there are.
We’re shown some oranges. We have to use counters to show how
many oranges there are. Let’s look at the first model. The first model doesn’t have enough
counters. There’s only one counter. Let’s look at the second model. We have one counter to show the
first orange and another counter to show the second orange. There are two counters and two
oranges.
These are the counters which show
how many oranges there are. There are two oranges and two
counters. Let’s count how many counters there
are in the third model. One, two, three. There are more counters than
oranges. The picture which shows the correct
number of counters to show how many oranges there are is the middle one, the one
which shows two counters.
Count the apples and match them
with the same number of blocks.
We’re shown a picture of some
apples. We have to show the number of
apples using the blocks. Let’s look at the first model. Can we match the number of blocks
to the number of apples? Let’s count. One apple, one block, two apples,
and two blocks. We have one more apple, but no more
blocks. Let’s try the second model. One apple, one block, two apples,
and two blocks, three apples, and three blocks. This is the model which shows three
blocks. There are three apples and three
blocks. The number of blocks in this model
matches the number of apples.
Place a counter for each crayon in
the five frame as you count them.
We’re shown a picture of some
crayons. We have to put a counter for each
crayon in the five frame. We’re shown three completed five
frames. We have to choose the one which
shows the same number as the crayons. We can quickly draw a five
frame. Then, we can add a counter or a
square for each crayon as we count them. One crayon, there is a one counter
or a one square. Two crayons, we have two crayons
and two squares or two counters in our five frame.
Which of the three five frames that
we’re given shows two? It’s the second five frame. One crayon, one counter, two
crayons, and two counters. The model which shows the same
number of counters as crayons is the five frame in the middle.
What have we learned in this
video? We’ve learned that we can use
models to help us represent objects. Models can help us to count
accurately. One, two, three.
