Lesson video

Hello, everyone; I'm Miss Saab.

Today, we're going to do some grammar learning together.

Today, we're going to explore compound sentences.

First, we're going to recap simple sentences, then we are going to define what a compound sentence is, and then finally, we are going to write some compound sentences.

In this lesson, you will need an exercise book or a paper, your pencil, and your brains to be switched on.

Can you pause the video now to grab your pencil and your paper? Great, you are now ready to start your learning.

First, we're going to recap simple sentences.

Can you help me to define what a simple sentence is by filling in these blanks? So a simple sentence consists of one hmm-hmm.

It makes hmm on its own.

Pause the video now to have a go.

Let's check.

A simple sentence consists of one main clause.

It makes sense on its own.

And we said a main clause is a little bit like a superhero Batman clause because it can make sense on its own, just like Batman can work on his own.

He can go on missions on his own.

Which of these is a simple sentence? Mrs. Clonkers shouted at Sophie, or as the cat chased the mouse? Can you point to the simple sentence? Let's check.

The simple sentence is, Mrs. Clonkers shouted at Sophie, because this makes sense on its own.

As the cat chased the mouse, that doesn't make sense on its own.

As the cat chased the mouse, what happened? We don't know the rest of it.

So that is not a simple sentence because it doesn't make sense on its own.

Now we are going to define what a compound sentence is.

Can you work out how many main clauses are in a compound sentence? Look at the picture to help you and tell your screen.

A compound sentence has hmm main clauses.

Let's check.

A compound sentence has two main clauses and they are joined together by a coordinating conjunction.

So my turn, coordinating conjunction.

Your turn.

And again, coordinating conjunction.

Well done! In the word conjunction, we have the smaller word junction; and a junction is where two roads or two railways meet.

So a coordinating conjunction helps to main clauses to meet together.

There are three different coordinating conjunctions: but, or, and, and we can remember them by thinking of a boa snake.

B for but, O for or, A for and.

We also need to remember to use a comma before the but and a comma before or.

And does not need a comma.

Can you spot the three coordinating conjunctions? Pause the video now to point to them.

Let's check.

So the three coordinating conjunctions are: but, and, or.

Just be careful that be in BOA stands for but, not because.

Can you help me to fill in these blanks to define what a compound sentence is.

A compound sentence consists of two hmm-hmm joined by a hmm-hmm, either hmm-hmm or hmm.

You can use these words to help you fill in the blanks.

Pause the video now to have a go.

Let's check.

So a compound sentence consists of two main clauses joined by a coordinating conjunction, either but, or, or and Well done, everyone; you are working so hard.

Can you now help me to match the sentence types to the pictures? How many main clauses are there in a simple sentence, and how many main clauses are there in a compound sentence? Can you pause the video now to have a go? Let's check.

So a simple sentence has one main clause and the compound sentence has two main clauses.

Well done! Now it's time for us to write some compound sentences but we need to know which BOA we need to use to join two main clauses together to form a compound sentence.

When do we use but, when do we use or, when do we use and? We use but to join two opposing ideas, so maybe a positive and a negative or two opposites.

For example, we have, she hates apples, she loves oranges.

We are going to join these two main clauses together using a but because they are two opposing ideas, hate and love are opposites.

So this is what the compound sentence looks like.

She hates apples, but she loves oranges.

Now we have one longer compound sentence with just one capital letter at the beginning and one full stop at the end.

And we need to remember to put the comma before but.

Now it's your turn.

Can you have a go at joining these two main clauses together using but to make a compound sentence? We are joining them together using but, because again, they are opposing ideas.

He was in pain, that's a negative, but he cycled to school.

So he still managed to go to school.

So that's a positive thing.

So can you pause the video now to write your compound sentence using but? Let's check it together.

So the longer compound sentence is, he was in pain, but he cycled to school.

We have one capital letter at the beginning, one full stop at the end, and a comma before but.

Can you pause the video now to check that you have all the correct punctuation and to make any changes if you need to.

Great, let's move on to the next coordinating conjunction.

We use or when we are talking about a choice or a consequence.

So for example, we can use or to join these two main clauses together.

You can eat now, or you can eat later because we are talking about a choice.

So here's what the compound sentence looks like.

You can eat now, or you can eat later.

Again one capital letter at the beginning, one full stop at the end, and a comma before or.

Now it's your turn.

Can you have a go at joining these two main clauses together using or.

And we are using or because this time we were talking about a consequence.

Be careful, or you will fall down as a consequence, as a result.

So can you pause the video now to write down your compound sentence using or to join these two main clauses together? Let's check.

So be careful, or you will fall down.

Again, ane capital letter at the beginning, one full stop at the end, and comma before or.

Can you pause the video now to check your work and make any changes if you need to.

Well done, everyone.

I love how you are going back to check your work Last coordinating conjunction, so we have and.

We use and when we are adding onto our first idea.

So for example, we can say, we ate ice cream and we played in the park.

So I am adding another thing that we did to my first main clause.

This is what the longer compound sentence looks like.

We ate ice cream and we played in the park.

So that's one longer sentence with one capital letter at the beginning and one full stop at the end and we don't need a comma before and.

Your turn.

Can you join these two main clauses, they swam in the pool; they had fun, together using an and? We are using and because we are adding another idea.

They swam in the pool, that's one thing, and they also had fun, that's another thing.

So can you pause the video now to write your longer compound sentence using and? Let's check.

So they swim in the pool and they had fun.

one capital letter at the beginning and one full stop at the end and we don't need a comma before and.

Can you pause the video now to check your work and make any changes? Fantastic! Now you know when we use but, and, or to join two main clauses together to make a longer compound sentence.

Can you help me to match the sentences to their sentence types? The colossal figure appeared.

Is that a simple sentence or a compound sentence? The thunder roared and the owl hooted incessantly.

Is that a simple sentence or a compound sentence? Can you pause the video now to have a go at matching them up? Let's check.

The colossal figure appeared.

That's a simple sentence.

We do not have any coordinating conjunctions.

We don't have an and, but, or, and it makes sense on its own.

The thunder roared and the owl hooted incessantly.

That's a compound sentence because we have a coordinating conjunction, and, joining two main clauses together.

The thunder roared.

That's a main clause; it makes sense on its own.

The owl hooted incessantly.

That's another main close because it makes sense on its own.

You are working so hard.

This is our final section.

Is this a compound sentence and how do you know? They swam in the pool and the beach.

Can you pause the video now to tell your screen what do you think? I think.

I love how you are trying to explain your thinking.

Let's check together.

So this is not a compound sentence.

Yes, there is a coordinating conjunction.

There's an and there, but it's not joining two main clauses.

They swam in the pool, that's the main clause; it makes sense on its own, but the beach, that's not a main clause; it doesn't make sense on its own.

And for a compound sentence, we need to have two main clauses that make sense on their own joined together by a coordinating conjunction, which can either be but, and, or.

Well done, everyone.

We have reached the end of our lesson.

Let's recap what we went through today.

So first, we recapped what a simple sentence is.

Then we defined what a compound sentence is.

So a compound sentence is two main clauses joined together by a coordinating conjunction.

The coordinating conjunctions are: but, and, or.

And finally, we had a go at writing some compound sentences and thinking when we need to use but to join two main clauses, when we use or, and when we need to use and to join two main clauses.

You have worked so hard today on your grammar.

There were some tricky bits, but you persevered, so well done for not giving up.

If you would like to, please share your work with a parent or carer or someone at home so that you can show off all of your amazing grammar learning today.

Well done, everyone; bye.
