Lesson video

Hello YouTube, my name is Miss Jones and I'm going to be teaching you maths today.

Before we start, I thought I'd introduce a little bit about myself.

My favourite hobby is riding my bike.

Recently, I rode my bike 65 miles.

Afterwards, I was very tired.

Let's begin our lesson.

Today, we are going to be recognising the place value of each digit in a three-digit number.

We will begin at looking at the place value of each digit in a three-digit number, or in a place value chart.

Then there will be a talk task followed by an independent task and then finishing off with a post-quiz.

You will need a pencil and some paper.

Please pause the video to get these items if you haven't done already.

Let's start with our new learning.

Here we have our place value chart with the ones and the tens column labelled.

Count with me as I place my ones in the ones column.

Are you ready? One, two, three, four, five, six, seven, eight, nine, 10.

Is that correct? When I have 10 ones, I need to regroup into the tens column.

I can replace my 10 ones with a 10 stick.

Now I have a 10, one 10 in my tens column, and zero ones.

Let's look at that now with our three digit numbers.

This time I'm going to add more tens.

Count with me, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.

This is correct, can I have 10 tens in my tens column? You're right.

When we have 10 tens we need to regroup just like we did with our ones.

We need to have another column on our place value chart, this is called the hundreds column.

Here I have replaced the 10 ten sticks with a hundred block.

This is because 10 ten sticks is the same as the 100 block.

Now I have 100 in my hundreds column, zero tens in my tens column and zero ones in my ones column.

My number is 100.

Here I have a picture of pairs that have been grouped into hundreds, tens and ones.

We need to match the picture to the correct number.

Say the sentences here aloud with me.

There are one, one, two, three ones.

There are one, two, three, four, five, six, seven tens.

And one, two, three, four, five, there are five hundreds.

The number is 573.

Now it's time for today's talk task.

Today for your talk task, I would like you to match up the pictures to the correct number.

Just like we did in the previous example, say the sentences aloud to help you.

Pause the video while you complete this task.

Let's look at the answers.

In the first example I've got one, two, three, four ones.

I haven't got any tens, I have one, two, three hundreds.

The number is 304.

In the second example I have one, two, three, four, five, six, seven ones.

One, two, two tens and one hundred.

The number is 127.

Now let's look at one example together with a common mistake that's often made when reading three digit numbers.

What mistake has been made here? I will give you a few seconds to think.

Are you ready? Tell me your answer.

That's right, three tens has been counted instead of 300.

There were three ones, there were zero tens, there were three hundreds.

Notice how when there were zero tens we still record this in the place value grid in order to write the number correctly.

Now we're going to look at some pictures and read what they represent and place them correctly in the place value chart.

So here we have one, two, three, four, five, six, seven ones.

There are one, two, three tens, and there is one hundred.

The number is, read it with me, 137.

Well done.

Now it's time for you to complete your independent task.

To do this, look at each image and next to it, write the number into the place value chart.

Pause the video to complete your task.

Resume once you have finished.

Here are the answers.

Let's go through them together.

In the first one, there are one, two, three, four, five, six ones.

There are one, two, three, four, five tens.

There are one, two, three hundreds.

The number is 356.

For the second one, there are one, two, three, four, five, six ones.

There are one, two, three, four, five tens.

There are no hundreds, so the number is 56.

For the third question, there are one, two, three, four, five, six ones.

There are one, two, three, four, five tens.

There are one, two, three, four, five hundreds.

The number is 556.

And then for the final question, there are one, two, three, four, five, six ones.

There are one, two, three, four, five tens.

And then there is one hundred.

The number is 156.

Now it's time to complete the post-quiz.

Pause the video whilst you do this.

Thank you for working so hard today, hopefully I'll see you again soon.
