Lesson video

Hello everybody, I hope you're ready for another exciting maths lesson.

Here we go.

Today we're going to be learning to compare numbers within 100 using a place value chart.

So that means we're going to be comparing numbers, using all of the information we learned yesterday.

This is lesson seven.

Wow, we've done so many lessons already for the topic of numbers to 100 and beyond.

You will need a paper and a pencil.

There are times when you will have to pause the video to have a go at some of the activities yourself.

Now let's get started.

Today we're going to be looking at a quick starting quiz to think about all the things we did yesterday.

Some key vocabulary, our star words, counting with numbers to 100, identifying numbers using a place value chart, writing numbers within 100, an independent task, some answers as well, and finally a quiz to see what we have learnt.

Now let's do our star words.

Star words, star words.

My turn then your turn.

Greater than, less than, equal to, value, most, least, compare.

I want you now to pause the video to complete your start of lesson quiz.

Once you've finished, you can restart the video.

Here we've got lots of dienes in our piece value charts.

This is super exciting cause we've already done counting with dienes already.

I want you to have a look at the place value chart, and think about what numbers are represented.

Remember, we need to count the tens first, and then count the ones.

Do you think you can count with me? I cant hear you.

Do you think you can come with me? Super, let's start with the first one.

One, two, three, four, five, six.

Six tens makes 60.

Now let's count the ones.

One, two, three, four, five, six, seven, eight, nine.

60 plus nine is equal to 69.

Now I want you to count the next place value chart, counting the tens first.

Shall we count it together? That's right, one, two, three, four, five, six, seven.

Seven tens makes 70, good job.

Now we've worked out the numbers we need to compare and see which one is greater.

I want you to have a think.

Which number do you think is greater? How did you get on? Did you manage to work it out? I know we need to look at the tens first.

So I know that seven tens is bigger than six tens.

So 70 has a greater value then 69.

What do you think? Did you think the same as me? Good job, thanks everyone for helping me.

Let's see if you can help me with some more.

What a great start to our lesson.

Here we've got a new place value chart, and I've got one, two, three, four, five.

Five tens makes 50, and one, two, three, four, five, six, seven.

Seven ones makes? 50 plus seven makes? 57, good job.

Now I'm wondering how many are in the next place value chart? Do you think you can help to count? One, two, three, four, five.

Five tens and one, two, three, four, five, six, seven, eight, nine, nine ones.

Five tens is equal to 50, plus nine ones is equal to 59.

There were 59 dienes in the place value chart.

Now we need to find out which place value chart has the greatest value.

Having a look at both the piece value charts, let's have a look at the tens.

Five and five tens, they're both the same.

Same, same, matchy-matchy.

That means we need to check the ones.

If the ones are different from each other, then we need to find out a which ones is the bigger number.

That means it has the greatest value.

I know that nine ones is greater than seven ones.

Therefore the number 59 must be the bigger number, which means it has the greatest value.

Have a look and see if you think the same as me.

Here we have a place value chart, but instead of the dienes we've got the numbers.

I need some help to put the dieness onto the place value chart.

Can you help me count the correct amount? Super, let's get started.

So the number eight.

We need eight tens, so let's count.

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

Eight tens, which makes? 80, good job.

Now let's count the ones.

One, two, three.

There are three ones.

Eight tens is equal to 80, and 80 add 3 is equal to? 83, good job.

The place value chart shows 83.

Now let's see if we can do this one.

Let's look at the tens first.

How many tens do we need? Can you shout it out? Can you shout it out to the ceiling? Super, we need seven tens.

Let's get ready to count.

One, two, three, four, five, six, seven.

Seven tens is equal to 70.

Now let's count the ones.

How many ones do we need? That's right, three ones.

One, two, three.

70 plus three is equal to 73.

Super, now let's compare the two place value charts, we've just worked out, 83 and 73.

We want to find out which one has the greatest value.

How do you know? What is the same and what is different about these numbers? So let's do this one together.

I can see that the ones are the same.

They both have three ones, but the tens are different.

One number has eight tens and the other one has seven tens.

I know that eight has a greater value than seven.

That must mean the number with eight tens is the greatest.

So 83 has a greater value than 73.

Can you tell me? Let's say it again.

83 has a greater value than 73.

Good job, now let's have a look at the place value charts.

They look a little bit different than the ones we have done before.

Instead of using dienes we've changed it to counters.

And so we've got a green counter and a yellow counter.

This makes it easier when we're doing our independent task, in case you want to draw them on some paper.

The green counters represent the tens dienes, and the yellow counters represent the ones dienes.

Here we have the number 31.

There are three tens and one, one.

The number is 31.

What is the next number? Who can tell me? Good job, 41.

Let's count how many tens.

One, two, three, four, there are four tens, and one, one, one.

Excellent work there.

We have the number 41 and we on the other place value chart we have the number 31.

Now, if we were to compare these numbers, which number would be greater? Let's look at the tens first.

Three tens and four tens.

I know that four tens is greater than three tens so the number 41 is greater than 31.

The number 31 is less than 41.

Use this to help us when we do our independent task.

Here we have some more numbers but I need some help to put the counters on the place value charts.

Can you help me? I want you to think about the first place value chart, and I want you to pause.

How many tens and how many ones do we need? How did you get on? I heard some of your thoughts, so if I'm right we need to use the green counters for the tens and the yellow counters to represent the ones, that means we need one green counter here for the 10, and eight yellow counters.

Let's count one, two, three, four, five, six, seven, eight.

Great counting every one.

How about the number 81? What do we need here? I think I heard someone say we need eight tens.

Can you count eight tens with me? One, two, three, four, five, six, seven, eight.

And now let's count out ones.

We only need one, one.

There we go, well done.

Eight tens makes 80, and we've got one, one, so 80 add one is 81.

And in the place value chart, we've got the other one, which is one ten and eight ones, which makes 18.

Now let's compare the numbers.

18 and 81.

81 has eight tens, which is a greater number.

Then 18, which only has one 10.

Super duper maths.

Let's see if we're ready for today's task.

Today's tasks, we're looking at the tens and ones, and we're comparing them on the place value chart.

Can you write the numbers down? I did one earlier as well.

I didn't have the colours green and yellow, so I used brown and pink to help me to write too.

Let's have a look.

The second task for today is different numbers now in the place value chart.

And this time you need to say which one is less than, and then we've got task three, which you need to complete too, and find out which one is greater than.

Finished already, super job.

Let's go through the answers.

Check that you've got the correct ones.

Done task two, super duper job.

And we did task three, great work.

Now I hope you had lots and lots of fun in today maths, and did lots of comparing of the numbers.

You might want to try your own numbers to compare.

Now, I want you to complete your end of lesson quiz to see how much you remembered, bye.
