Lesson video

Hello, I'm Mr. Marsh and welcome to this spelling lesson.

Now in this lesson today, we're going to do an investigation about a suffix.

Now a suffix is something that you put at the end of a word that changes its meaning.

And the suffix that we're going to look at today, is the suffix O-U-S.

So when you're ready, let's begin today's lesson.

Now, before we begin the lesson, I just want us to have a little look at the agenda, so you're really familiar with what we're going to do throughout this lesson.

So in the first part, so we're going to look at some key vocabulary.

And that vocabulary is going to help us with our understanding, as we look and study the suffix O-U-S.

The next part of the lesson, is going to be the main part, where we're going to do an investigation.

And the purpose of that investigation, is to try and come up with some rules, that can help us when we have words that use the suffix O-U-S.

Now it's great to have rules when we're spelling, because if we come across a word, and we're not really sure, maybe how to spell it, well, then we can always think about the rules that we've learned, and that might help us spell the word correctly.

And then in the last part of this lesson, we're going to set some spelling words, based upon the suffix O-U-S.

Okay, what I want you to do now, you're definitely going to need something to write on.

So make sure you've got an exercise book, or a pad, or a piece of paper.

You're going to need something to write with.

So you're getting into pen or pencil, and make sure that brain of yours is ready to go.

If you need to go and get anything before you start the lesson, pause the video for me now, and go away and get it.

Okay, off you go.

Okay, the first thing we're going to do in this lesson, is look at some key vocabulary.

And like I said earlier, the key thing we're looking for here, is that if we understand the key vocabulary, it's going to help with our learning, as we go through the lesson.

I'm going to do something called my turn, your turn.

So when I pointed myself, I'm going to say the word, and when I point at you, I want you to repeat it back to me, okay? So suffix, a suffix is a group of letters at the end of a word that change its meaning.

Root word, now a root word is a word, or a part of a word that can form a new word, through the addition of a prefix, which is not what we're looking at today, but a prefix goes at the start of word.

Or what we are looking at today, a suffix.

So let me read those again.

A root word, is a word or part of a word that can form a new word, through the addition of a prefix or a suffix.

Okay, so that was our key vocabulary.

Remember those who need to remember suffix, and the root word as we go through the lesson, 'cause that's going to really help with our understanding, especially in this main part of our lesson now, where we're going to investigate the suffix O-U-S.

And generate some rules that can help us with our spelling.

Okay, let's begin our investigation.

Here are two words cautious.

So a cautious person is someone who's very careful, may approach things cautiously.

Spacious, so you might think about word space, as something that describes as spacious, means there's lots of room to move around in.

Okay, cautious and spacious.

I want you to pause the video, and I want you to say those words to yourself.

I also want you to study those words.

What do you notice about them? Okay, pause the video for me now.

Okay, well what did you see? Did you notice anything about them? When you heard them, when you said cautious and spacious? Well, what did you notice? Do they sound the same? Did they sound different? I'll say that one more time, listen in, cautious, spacious.

Well, they both got that /sh/ sound, haven't they? Cautious, spacious.

What makes it tricky to know whether it's, well, look, I've highlighted T-I, and I've highlighted C-I.

Why is that tricky to know which of those it is? Cautious, spacious.

Why do you think it's tricky? Well can you hear that they sound really similar.

Cautious, spacious.

So they both use that O-U-S suffix, but they both got that /sh/ sound, before the suffix, cautious, spacious.

So it's really tricky to know whether the word that I was spelling ends in T-I, and then the suffix O-U-S, or C-I, and the suffix O-U-S.

So that's where we need to do an investigation.

That's why we need to have some rules that help me know whether it's T-I, then the suffix O-U-S, or C-I, and the suffix O-U-S.

Okay, let's start doing our investigation.

Here is two words, nutrition and then it becomes nutritious.

Nutrition and nutritious.

So the suffix O-U-S, has been added to this word.

But what's happened to nutrition when we've added the suffix? What do you notice? There's my pause symbol.

So I want you to pause the video, and have a think.

What do you notice? Okay, off you go.

So, what did you notice? Well, you might have spotted the O-U-S suffix, but nutrition, nutritious.

I want you to pause the video again, because I've made some of the letters in bold, made them a bit bigger.

Does that help you work out, maybe what's happened here? Pause the video for me now.

Okay, well did you notice here that nutrition ends in I-O-N? So my root word here, or my word is ending I-O-N.

But it becomes nutritious.

So we've got that suffix O-U-S.

So if the root word ends in I-O-N, like in nutrition, then you use the O-U-S suffix.

But you remove the N, and you add U-S.

So here, I end up with T-I, and then the suffix O-U-S.

So we still got the /sh/ sound, before my suffix.

But because my root word had T-I-O-N, well that became T-I-O-U-S.

Okay, see if you can add the suffix O-U-S to infection.

My turn, infection.

So he had an infection.

How can you make that? Or how can you add the suffix O-U-S? I want you to write it down for me.

Pause the video, and write it down.

Off you go.

Okay, how did you get on? Well, remember infection ends I-O-N.

So I needed to move the N, and add U-S.

So I end up with the suffix O-U-S at the end of infectious.

So it's still got the /sh/ sound, but because my root word had T-I, then when I'm adding the suffix O-U-S, we'll have T-I-O-U-S.

So, a quick recap.

If the root word ends in I-O-N, so infection, and use the O-U-S suffix.

Remove the N, and add U-S.

So I end up with T-I-O-U-S.

Infection becomes infectious.

It was an infectious disease.

Okay, let's go back to nutrition, and nutritious.

I'll read these two sentences to you.

Through his meals, he gets good nutrition.

He ate a good nutritious meal.

What we're going to focus on now, is how that suffix O-U-S changes the word class of a word.

So I want you to think, in the first sentence, what word class is nutrition? Through his meals, he gets good nutrition.

So by word class, I mean, is it a noun, a verb, an adjective and adverb.

And there are many others.

Or, when we look at it, when it become to nutritious, what word class is it, he ate a good nutritious meal.

Okay, I'm going to give you a bit of a clue.

One of them is a noun, a person, place or thing.

And the other one is an adjective, a describing word.

So, is nutrition a noun, or an adjective? Or is nutritious a noun or an adjective? Pause the video, and think how is each word used in each sentence? Okay, off you go.

Okay, well how did you go on? Through his meals he gets good nutrition.

Does that sound like a describing, is it describing anything? Or is it sound like a person, place or thing? He ate a good nutritious meal.

Does it sound like it's describing something, describing a noun? Or does it sound like a noun itself? Is it a person, place or thing? Okay, well let's have a look.

Nutrition is noun.

Through his meals, he gets good nutrition.

'Cause nutrition is a thing.

But he ate a good nutritious meal.

Well, there is an adjective, because we're describing the meal.

So when you change it you change it from the I-O-N ending of the word, to using the suffix O-U-S, generally it changes from a noun into an adjective.

So that can help us when we're spelling, because if we hear the word ous, at the end, word like nutritious, we can think, "Okay, is it describing a noun? "Yes, okay, well then I know it's an adjective." Great, let's look at these two words.

Space, spacious.

Again, I want you to think about the suffix O-U-S.

And I want you to think how has space changed to become spacious.

What do you notice? Remember they both still got the /sh/ sound in space, and then spacious.

Okay, your turn.

Pause the video for me now.

Okay, what did you notice? Well, here space, and then I've highlighted spacious.

I've highlighted the I.

Pause the video for me again.

How is space changed into spacious, with the suffix O-U-S? Okay, do that for me now.

Well, what did you notice? Well here our root word, to part a word, to form a new word, with the addition of the suffix O-U-S.

But what happened to space, to becomes spacious? Well, if the root word ends in E, so as in space, you use the O-U-S suffix, but you do that by removing the E, add an I, and then add the O-U-S suffix.

So space becomes spacious.

Let me repeat that rule again.

If my word ends in an E, my root word ends in an E, then use the O-U-S suffix by removing the E, adding an I, and then add the O-U-S suffix.

So space becomes spacious.

Still got that /sh/ sound.

But this time, we've got C-I and then O-U-S.

Okay, your turn.

Can you change the word grace, using the word, sorry, using the suffix O-U-S.

So grace, is going to become gracious.

I want to write it down for me, think about the rule that we've just discovered.

Okay, off you go.

Okay, how did you get on? Well, grace becomes gracious, like I said.

But again, have a quick think.

What was our rule? What's happened when we've added the O-U-S suffix to our root word.

Grace has become gracious.

So what have we done, when we've added the suffix O-U-S? Let's see how you remember the rule.

So if the root word ends in E here, we've got grace.

So they carried themselves with grace, which means they move elegantly.

We need to remove the E, then use the O-U-S suffix, by removing the E, adding an I, and then adding the O-U-S suffix.

So grace becomes gracious.

So they moved with grace.

He was a gracious individual.

He was gracious in defeat.

Okay, let's move back to looking at space and spacious.

I've got two sentences again, and we're going to look at word class, like we did when we looked at nutrition and nutritious.

Here are two sentences.

Listen to me say them space them.

Space, so there is a lot of space in their house.

This house, or their house is spacious.

There was a lot of space in their house.

Their house is spacious.

So again, one of these is a noun.

And one of them is an adjective.

Remember a noun is a person, place, or thing.

And an adjective is a describing word.

Okay, pause the video, which one is which? Off you go.

Right should we see how you got on? See if you got it right.

But if you didn't, it doesn't matter.

That's how we become better learners.

We learn from our mistakes.

So let's see how you got on.

So there's a lot of space in their house, well space is a thing.

So therefore, it's a noun.

And their house is spacious.

Well, we're describing what their house is like.

Therefore it's an adjective.

So again, we know if we add the suffix O-U-S, then it changes a noun from an, sorry, it changes a word from a noun into an adjective.

Okay, time to test how you got on, and what you can remember about these rules.

So let me read both our rules.

First rule, if the root word ends in E, then use that ous suffix, O-U-S suffix.

Remove the E, add an I, and add the O-U-S suffix.

Or is it our other rule? If the root word ends in I-O-N, then use the O-U-S suffix, you remove the N, and add U-S to the end of the word.

So it's your turn to have a go.

We've got caution.

They moved with caution.

And that's going to become cautious.

They were a cautious individual.

What rule do I need to follow, to know how I can correctly spell by adding this suffix O-U-S.

Okay, off you go.

How did you get on? Did you work it out? If you're not quite sure, you can always pause the video again, and give it a bit more thought.

But let's have a look.

Well, here, my word ends in, my root word ends in I-O-N.

So caution will change to cautious, by removing the N, adding U-S, and then I end up with the O-U-S suffix at the end.

So cautious, okay? Now we have malice.

My turn, malice.

So doing something maliciously, or malicious.

So doing something with malice, is doing something quite aggressive, with quite an aggressive intent.

Again, which of the rules, think about them, does this follow? Okay, off you go.

It follows off first rule, doesn't it? Because our word here ends in E.

So then we use the O-U-S suffix.

You remove the E, add an I, and then add the O-U-S suffix.

So malice becomes malicious.

Still got the /sh/ sound, but this time it's C-I, and then O-U-S.

Okay, so that's our investigation.

We've discovered two rules about using the O-U-S suffix.

Now we're going to set some spelling words, based upon those rules.

What I want you to do, is I want you to make sure you copy down these spellings correctly, and over the next week or so, I want you to take them away, and I want you to practise them in the most effective way, which is little and often.

Maybe 10, 15 minutes a day, if you can.

And using some spelling practise strategies, is the best way that we can be effective spelling learners.

Okay, let's have a look at our spelling words.

There are 10 spelling words, and I'm going to go through each and every one of them with you.

Just in case, if you're not sure, and you go, "Mr. Marsh, I don't know the meaning of that word." Well, we're going to look at each one of them.

So don't panic.

I'm going to do my turn, your turn, before every word, just so we're clear how we pronounce them.

Spacious, the house was spacious.

So it had lots of room.

Conscious, so if you're talking about someone who's conscious, it means that they're aware.

So he was conscious that there was a lot going on around him.

He was really aware that there was a lot going on around him.

Gracious, so someone who's gracious.

You might be gracious in defeat.

You might have heard that phrase.

And that means someone that, even though they've lost, they don't throw a big strop.

They accept that they've lost, and they congratulate their opponents.

They were gracious in defeat.

Vicious, so vicious comes from the word vice, so if someone who's vicious, is someone who's like maybe really aggressive.

Delicious, now I said delicious, because it always makes me think about food, delicious food.

Cautious, so a cautious individual, is someone who maybe does things very carefully.

Contentious, so contentious is something that maybe not everyone agrees with.

You might have a contentious decision, which might mean that some people might agree with it, but others might not, it's contentious.

Ambitious, someone is ambitious.

It means that they think that, they're looking to do the best that they can.

They are striving, they're looking to always improve.

They might be an ambitious individual.

Superstitious, so someone who's superstitious may believe in things that maybe not others believe in, but maybe they always want to do things in the same way.

I'm a bit superstitious, because I always want to, when I leave my house, make sure that I check all the doors in a certain order, so that I know that they're all locked.

That makes me a little superstitious.

Infectious, so you might talk about this to do with an illness, or maybe a disease.

So if someone is infectious, it means means that people could maybe catch that from them, infectious.

But you also might describe other things as laughter being infectious.

If someone's laughing, and you start laughing along with them about something, you could describe that laughter as being infectious, 'cause you have caught on, and kind of caught it from them.

Okay, what I want you to do now, is I want you to pause the video, and make sure you've copied down each, and every one of those spellings really carefully.

'Cause we need to make sure we have done, so that when we're practising , we're actually copying, and practising the right spellings.

Okay, pause the video, and do that for me now.

Fantastic, well just before we finish the lesson, I just want us to do a quick recap of everything we've done in this lesson, because it's worth celebrating, definitely.

So the first thing that we did, is that we looked at some key vocabulary.

We looked at the word suffix, the word root word.

And both of those things helped us with our understanding, when we moved on to the next part of our lesson, where we carried out our investigation, and generated our two rules related to the suffix O-U-S.

And then finally, we've just set 10 spelling words.

And those 10 spelling words are based upon those two rules that we've looked at, for the suffix O-U-S.

Congratulations, you've completed this lesson, and you worked really hard.

'Cause that investigation was tricky.

What I want you to do now, I want you to take those spelling words, practise little and often, over the next week or so.

So that in the next lesson, you can be ready to do a spelling test.

Okay, I hope you enjoyed the lesson.

I certainly did, and I'll see you next time, bye bye.
