Lesson video

Hi, and welcome back to your unit on number sense.

Today, we are going to be using comparative symbols to compare numbers within 100.

Now, today, we are going to be learning a song or practising a song.

If you already know it with an alligator, we can using different comparatives symbols to compare numbers.

I'm really excited because I love this song, and I love this lesson let's get started.

Here, is our lesson agenda for today.

We're going to be looking at comparison symbols.

We'll do some exploring, practising what we've learned, and then we're going to do our independent task and quiz.

So let's get started with this lesson before we continue with our learning.

That's a great song that will help us today with our comparative symbols.

And it's all about an alligator with a hungry tummy.

If you know it join in.

Alligator Alligator which one will you eat? The greater one, the smaller one, it will be sweet.

Now we know our alligator has got a hungry tummy and he's feeling a little bit greedy therefore he's going to be want to be facing towards the greater number.

So remember our alligators jaws, are going to be facing the greater number today.

So now we have sung our alligator song.

We can move on a do some exploring and we know our alligator is always going to be facing the greater amount because he's got a greedy belly.

So make sure our comparison alligators are always facing the greater number.

We also have a third symbol, which is this one, which is equal to.

This is where we know that two numbers are equal or they are the same.

For example, four is equal to four.

Brilliant let's move on together.

Here, we have some different numbers.

We have 43, 42, 40, 30 and 13.

We also have that dienes representation.

It's now a job to put them into correct order using our comparison symbols or alligator jaws.

Here are alligator jaws that already facing ready for the bigger number.

Our first number is going to be thirteen because it is the smallest number.

We know that 30 is greater than 13 and 13 is less than 30 because 30 has three tens and 13 has one 10.

Our third number is 40.

40 is greater than 30 and 30 is less than 40.

This is why all crocodile jaws or comparative symbol it's facing towards 40.

Our next number is 42 And there are their comparison dienes and our final number is 43.

Now it's your turn.

We have the numbers that 32, 31, 29 and 37, you now need to put them into the correct order.

Now remember our crocodile is facing towards the greater number.

So pause this video and put the numbers into the correct circles.

Good job, well done.

Let's keep going, let's have a look at the answers.

So our first number will be 29 followed by 31 because 31 is greater than 29 and on here it says 29 is less than 31.

We have the 32 followed by 37.

Good job.

But what happens when the symbols are the other way around? Now, we can see that they are facing the other way.

So we have something is greater something, is greater than something, is greater then something.

So I know the largest number needs to go first because it's the greatest number therefore the first number will be 37.

It will then be followed by the 32.

Now remember our crocodile is always facing the greatest number, so it will be followed by 31.

And finally, by 29, you can see our crocodile is working its way up from 29, all the way up to 37.

So now it's you turn.

You're going to be completing your independent task, where you're going to be ordering the numbers into the correct order using our alligators.

Now remember alligators really greedy and you'll always be facing the greater number.

So here are full set of numbers.

Let's go through them quickly.

Set number one, 33, 31, 29, 37, set number two, 12, 21 18, 19, set number three, 42 43 53 and 50, and set number four, 12, 8, 2, 18 and 2.

Don't forget to pause this video while you complete your independent task.

Well done everybody.

Now, it's time to tick and fixed.

So make sure you have a pen or pencil in a different colour.

And here we go.

Our first set.

29, 31, 32, 37.

Or if you wanted to challenge yourself, you would have done it in the other way.

That's the 37, 32, 31 and 29.

Make sure you pay attention to which ways those alligators are facing.

Set number two 12, 18, 19, 21, or 21, 19, 18, 12.

Set number three, 42, 43, 50, 53 or 53 50 43, 42.

Remember to be careful of those alligators.

The final set.

2 is equal to 2, 8, 12, 18, or 18, 12, 8, 2 is equal to 2.

Great job, everybody give yourselves a big pat on the back.

If you'd like to, please ask your parent or carer to share your work on Instagram, Facebook, or Twitter time @OakNational and #LearnwithOak.

It's been wonderful learning with you today, and I can't wait to get into another lesson with you.

So now it's time to complete the quiz, good luck.

See you again soon.

Bye.
