Lesson video

Hi there, my name is Byrne Smith and today we're going to be doing some spelling in particular we're going to be looking at the O-U-S suffix, today we'll have a chance to practise and apply our knowledge of the O-U-S suffiX.

I'm really looking forward to that So come along Here's the agenda for today's lesson first, we're going to look at some key vocabulary.

Then we're going to recap the spelling rules we've learned so far.

Next, we'll learn a brand new strategy before finally taking our test in this lesson, you'll need an exercise book or paper a pencil, and of course last but not least your brain.

If you need to rush for getting any of these things, pause the video now let's run through some key vocabulary.

My turn your turn which means repeat after me.

Suffix.

A Suffix is a group of letters at the end of a word that change its meaning and sometimes class.

Adjective.

An adjective is a word that describes a noun it tells you what it's like.

Noun.

A noun is a person place or thing.

Root word.

A root word is the most basic version of a word before it's had any prefixes or suffixes added.

Let's recap the rules we've learned about today's suffix.

The suffix we're looking at is O-U-S Spell it like this, O-U-S OUS is used to change words into adjectives.

Some of these words do not have an obvious root word, like in this instance, enormous.

This is often because the root word actually comes from another language and therefore isn't recognisable in English.

When words do have an obvious root, we can use the root to help us understand their spelling.

Like here for example, poisonous has the root word poison.

If I'm struggling to spell the word poisonous, I can apply my understanding of the O-U-S spelling rules and I can get that poison becomes poisonous.

Let's remind ourselves of the four main rules for adding the suffix First.

The first is just add O-U-S.

In many instances, you can just add O-U-S without changing the spelling of the root word.

The second is change O-U-R to O-R and then add O-U-S if a root word ends in O-U-R it's first necessary to change it to O-R before adding O-U-S.

The third rule is remove the E and add O-U-S.

This is a rule we see really quite often with suffixes before adding O-U-S it's necessary to remove the E at the end of the root word.

Finally, we have removed the Y add I and add O-U-S this is another rule that's very common when it comes to suffixes.

Let's have a quick challenge here I'm giving you a root word Vary your job is to tell me which of the four rules applies and then have a go at spelling the O-U-S version of this word Vary.

Pause the video now and have a go.

Okay, great.

The rule that applies in this instance is this one seems Vary ends in a Y it's first necessary to remove the I before adding O-U-S Vary becomes Various and there is the I.

Let's have another go.

In this instance, the word is, Continue Pause the video and have a go.

Okay.

The rule that applies is this one Continue ends in an E therefore, before adding O-U-S, we must remove the E Continue becomes Continuous.

Next word, Poison.

Pause the video now and have a go.

Okay, great.

When we add O-U-S to the word poison there's nothing we need to do.

Therefore, the rule we apply is this one you can just add O-U-S in these instances, it's necessary to rely on how the word sounds, Poisonous.

I can hear that, that there's not much change from the root word, Poison poison becomes poisonous.

Next word, Odour, pause the video and have a go.

Okay.

The rule that applies in this instance is this one, since Odour ends in O-U-R, we first have to change the O-U-R to O-R before we can add O-U-S Odour becomes Odorous, and there's our suffix.

Here I've had a go at spelling the word Dangerous.

Now I know that the word Dangerous has the O-U-S suffix at the end And I also know that it comes from the root word Danger.

The problem is I'm not sure which of these two options is correct, but I've tried my best.

I need your help deciding between the two pause the video and have a go.

Okay, great.

In this instance, we're having to add the O-U-S suffix to the root to form the adjective and the correct option is this one what's gone wrong with the other option.

Pause the video now and have a go.

Okay.

With the other option of adding I before adding O-U-S now is sometimes necessary to put an I before the O-U-S but not in this instance only when I'm replacing a Y at the end of the root.

Now I'm having more trouble So I need your help here we have the word humourous.

I've had a go and I have two options help me out, which is Correct? And why have I made a mistake with the other one? Okay, great.

The correct option is this one, but what's gone wrong? I can see that in the other option I've left O-U-R at the end of my root word and actually if a root word ends in, O-U-R I have to replace it with, that's right O-R before adding O-U-S.

How about here? Two options, which is correct and why? Pause it again now and have the go okay.

The correct option is this one any other option you can see I've left the E at the end of my root word Fame if the root word ends in E it's necessary to remove the E before adding O-U-S so Fame becomes Famous with no E in this instance, I've tried to spell the word Various.

I know that various makes use of the root word Vary as well as the O-U-S suffix.

The question is which of these two options is correct and why? Pause the video and have the go Okay.

The correct option is this one.

If the root ends in a Y we have to first remove the Y before adding O-U-S.

In fact, we don't just remove the Y We replace it with an I which you can see I've done here with the other option I haven't removed the Y and I haven't replaced it with an I.

I want to let you in on a little secret all to do with the sound.

You often hear the sound before the suffix O-U-S.

There's a top tip, which can help us spell any words ending in sound plus O-U-S.

Let's have a look at some examples.

Serious, you can hear it in this instance, sound is felt with an I Obvious, once again in this instance, sound is spelled with an I Previous.

Hold on a second again sound is spelled with an I Furious.

Again I can hear that sound and it's spelled with an I.

It seems to me as though most often the sound before O-U-S is spelled with an I However, not always.

Hideous in this instance the sound is spelled with an E looking at these on balance I think it's fair to say that our best bet is to spell the sound with an I rather than an E So if ever you're unsure, I would go with I let's learn a brand new spelling strategy.

The strategy we're learning today is called Jumble and Order.

This is a strategy I really, really like Let's use the strategy on the word various in order to have a go at this strategy you have two options.

Option Number one write out all of the letters from your word on paper and cut them out into little squares Sort of like I've got here.

You can then jumble them up and your task is to put them back in the right order.

Obviously it's really useful if you hang onto these little squares so you can use them again and again, and again if this isn't possible, you can write out the letters in a jumbled order on a piece of paper, then your task is to reorder them here we have the letters from the word Various and they've been jumbled.

My task is to put them back in order Paraah! Done.

This is a really fun strategy the question is, why is this a useful strategy? Firstly, you're forced to interact with the word and think about everything that it contains.

This process is great because it slows things down and it forces you to think a bit more deeply about your word secondly, you have to think about every single letter in the word you can't rush on and forget that is because you have to write them down before you cut them out.

Lastly, it's physical especially if you're creating little cards that you can cut out since we're having to audit them and move them about we're using our body quite a lot This makes a nice change and it means that we're really engaging and interacting with the word which can be a really useful tool to help us remember.

Time for us to have a practise on some of this week's Spelling words.

I've given you four options here.

However, you can practise on any of the words it's up to you pause the video now and have a go.

Okay.

Great time for our test I like to write numbers one to ten pause the video now to do this.

Okay.

I'm going to read out each of the words slowly, twice and then going to put them into an appropriate sentence.

I'd like you to pause the video whenever you need more time don't feel as though you're in a rush you don't have to do things at the same time As I'm saying that please, please, please, if necessary pause the video and take your time.

Just want to remind you that getting words wrong is not a big deal so I don't want you to feel overly pressurised doing this test.

This is just a really good chance to see where we're at.
