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.
