Counting in twos, fives and tens.

Hello everybody, I'm Miss Sidhu.

And we're going to be doing some wonderful maths with you today.

And today's lesson we are going to be learning to count in twos, fives, and tens from a given number within 50.

Now let's get started.

Welcome to today's lesson.

We are going to be counting in twos, counting in fives and counting in tens.

We also have an independent task to complete and an end of lesson quiz to see everything that we have learnt.

In this lesson, you will need a pencil and a paper and a number squared to 50.

But let's begin this lesson with a brainteaser.

Now, which number has the greatest value? And how do you know? So looking at the two numbers, 25 and 41, which number has the greatest value and how do you know? You may want to pause the video to have a go.

To think about which number has the greatest value.

How did you get on? Did you find out which number has the greatest value? Now let's use the bead strings to help us to find out which value is the greatest.

So looking at the bead strings, 25 has two tens and five ones.

The number 41 has four tens, and one, one.

41 has the greatest value because it has more tens than 25.

Did you get the same answer as me? Well done.

We have some cubes.

How can we count these cubes? Have a think.

And after three, I want you to say your answer.

How can we count these cubes? One, two, three.

Lots of different answers.

Let's have a look.

If you've got the same as me.

We can count in tens, so if we count these cubes in tens, how many cubes are there altogether? Let's count.

10, 20, 30, there are 30 cubes altogether.

Great counting.

Let's have a look at this one.

How can we count these cubes? Can we use more than one strategy? So how can we count these cubes? I want you to say after three.

One, two, three, Oh, lots of really good ideas.

Let's have a look, if you've got the same as me.

Now, you can count these cubes in tens and twos.

I want you to pause the video and see if you can find the total amount counting in tens and twos, pause and freeze, macaroni cheese.

So how many of have we got all together? There are 10, 20, 30, 32, 34, 36.

There are 36 cubes altogether, counting in tens and twos.

You've done some amazing counting in twos, fives and tens today.

Now I think you're ready for the independent task.

For today's independent task.

I want you to count the cubes in either twos, fives, and tens, and then write the total in the box.

Here we've got lots of cubes.

I want you to count the cubes in either twos, fives, and tens, and then write the total in the box.

You may need to use a number square to help you.

I want you to pause the video to complete your task and then resume once you're finished.

The total cubes are 16, altogether, there are 16 cubes altogether.

You may count in 10 and then twos.

This time you can count in tens and you might count in tens and then five and then twos.

You might count in just fives or maybe just twos and then add the rest of them at the end.

There are 49 cubes altogether if you would like to share your work with Oak National, please ask your parent or carer to share your work on Twitter, Instagram, or Facebook tagging @OakNational and #LearnwithOak Now, I want you to complete your quiz to see everything that you've learned, because you have done an amazing job today in counting in twos, fives and tens.

And now that's the end of the lesson.

Bye.
