Lesson video

Hello and welcome to today's spelling lesson.

I'm Mr. Moss.

I love spelling, and I'm really looking forward to teaching you.

With you for today's lesson, you need to bring your looking eyes, your listening ears, and your thinking brains, as well as that something to write with and write on, and someone to talk to would be great.

Let's get on with today's lesson then.

In today's lesson, we're going to be using and spelling the prefix un.

The outcome is, "I can spell words using the prefix un." Here are the key words for today's learning.

My turn, your turn, and make sure I can hear you saying these back to me.

Prefix, root word, brilliant.

A prefix then is a letter or group of letters added to the beginning of a word, which creates a new word.

We've been looking at prefixes and suffixes.

Suffixes are added to the end of a word.

A prefix is pre, okay? Coming before the word.

A root word then is that base word onto which either a prefix or a suffix are added.

Here's the outline for today's lesson.

We're using and spelling the prefix un.

in the first part of today's lesson, in the first learning cycle, we're going to look at the prefix un, and in the second part we're going to spell some words with the prefix un, and then apply the spelling of these words as well.

Let's get on with looking at this prefix then.

A prefix is a letter or group of letters added to the starter word to change its meaning and create a new word.

Unkind, my root word here is kind, and I've added to the beginning of it un, to create the word unkind.

Here's another example, un, unhappy.

Happy is my root word.

I've added the un prefix to the beginning of happy to create a new word, unhappy.

This changes the meaning of happy as well, from being happy to being unhappy, they're opposites.

Pre, view, view here is my root word, pre is my prefix.

I create the word preview, which means to view or watch something before it comes out, like you might preview a TV show.

Understanding prefixes can help us to work out the meaning of unfamiliar words.

So let's have a read of some words.

Unhappy, my turn, your turn, unhappy.

Undo, uncover, unfair.

Unlock, untie, unhealthy.

What do you notice about all of these words then? What's been added to the root words here? Pause the video and have a think, what prefix do you spot? Great, absolutely we can see here, oh, and there was one more there, unzip, okay.

So absolutely we can spot here, they all begin with that prefix un.

The prefix un changes the meaning of the word that they're being added to, by showing a reversal or opposite.

The prefix un can mean not.

So if we look at the word happy, for instance, and we add un to the start of it to create unhappy, it means not happy.

Look how the meaning of these words changes when the prefix un is added.

Happy, unhappy means not feeling happy.

Kind, unkind means not to be kind, not to be nice.

Lock becomes unlock, which means to open or release a lock, to make it not be locked.

Tie, and this is tie as in to tie a knot here.

Untie, which means to undo the knot, so that it is no longer tied together.

For this check, I'd like you to match the words with the same root word.

So we have the words here, my turn, your turn.

Happy, tie, kind, do.

Could you match our words here? Those root words with the words that have had their prefix added to them.

Pause the video, match them now.

Good job team, so let's have a look.

Happy and unhappy match, with our prefix un added before it.

Notice here how the root word has not had to change.

Tie pairs with untie.

Again, just adding that prefix un, our root word hasn't changed.

Kind, unkind, do, undo.

And these are obviously all opposites, aren't they? Pause the video and see how you did.

Great, so here's another check as well.

Match the definition to the word with the un prefix.

So we've got three un words here, unhappy, unzip, uncooked, and we've got three definitions, to open or separate a zip, not cooked or heated, not feeling joy or happiness.

Pause the video and match the words to their definition now.

Good job.

So to open or separate a zip, that is unzip.

It's the opposite of zip up, I unzip.

Not cooked or heated is uncooked, and not feeling joy or happiness is unhappy.

Remember that prefix un can often mean not.

Notice also how the root words when adding the prefix un had not changed.

Pause the video and check, see how you did.

So, got a little practise for us to do now.

Gonna give us some sentences, and they're gonna contain some blanks, and I'd like you to fill in the blanks.

Give consideration to the learning we've done so far in this cycle about the prefix un.

Un is a type of mm.

A prefix is a letter or group of letters added to the mm of a word to change its meaning.

And the prefix un usually means mm.

Pause the video now and fill in the blanks.

Really great job, let's see how you did then.

Un is a type of prefix.

Remember, prefix is something that we add to the beginning of a word.

A prefix is a letter or group of letters added to the start or beginning of a word to change its meaning, and the prefix un usually means not.

Check, pause the video, see how you did.

Onto then our next learning cycle, which is going to be spelling words with the prefix un.

The spelling of the root word does not change when the prefix un is added.

You've been looking at many suffixes, I'm sure in your learning, and often when we add suffixes to the end of a word, that root word changes.

But the prefix un coming at the beginning of a word does not change that root word, which makes it quite straightforward for us to spell words with it added to.

Un plus kind, unkind, unkind.

Un plus, happy, unhappy, unhappy.

Un plus healthy, unhealthy.

Un plus zip, unzip.

So if you know the spelling of the root word, then you can work out the spelling of your new word very easily, because of course the spelling of both the un and the root word aren't going to change.

You're just gonna combine them together.

Unfair, I'm sure you know how to spell unfair for me now.

We just have have our prefix un, and then our root word fair.

And this is fair, as in, "That's not fair," the idea of fairness, something being unjust or just, so it becomes unfair.

Have a look here, untie.

Hmm, how do you think I'm going to spell untie then? Is my root word going to change? Is my un prefix going to change? Pause the video and see if you can spell the word untie for me.

Okay, it's gonna be spelled like this.

Un, my prefix, and then tie.

Again, that root word's not changing.

Uncooked, now be careful with the word cooked, because it sounds like a T at the end, but it's our E-D we have at the end there, that suffix E-D.

But this word uncooked, is either my prefix or my root word going to change? Nope.

I'm just going to combine them to create a new word, uncooked, which means not cooked.

Unfold, if I fold something up and then I unfold it, I do the opposite.

It's something that's not folded, so it becomes unfold.

So let's see if you can add an un prefix to a root word.

Choose the correct spelling from the three we have below.

My root word, that base word onto which you're gonna add the prefix un is healthy.

So which is the correct spelling of unhealthy? Pause the video and decide now.

Great, let's have a look.

A says unhealthy, now think about this.

Does our spelling of the root word change? No.

We said no it doesn't when we add that prefix un.

So I'm just gonna have that root word healthy, and I'm gonna have my prefix un.

So my correct spelling is C, it's U-N-H-E-A-L-T-H-Y, unhealthy.

My spelling of the word healthy has not changed, and I've added that un before it.

Have a look here for me, choose the correct spelling.

My root word is happy.

I'm going to add the prefix un, and spell the word unhappy for me.

Pause the video, and select the correct spelling now.

Great, again think about the rule that we said.

When adding the prefix un, the spelling of the root word does not change.

So our correct spelling is B, okay? 'Cause that spelling of happy hasn't changed, and I've just added my prefix un to create my new word unhappy, meaning not happy.

So we're gonna have a go now at writing some words.

I'd really like us to take our time when doing this.

Consider the rules that we've looked at.

I'm gonna say the words to you.

They're all going to have the prefix un in them.

Remember, does that root word change? Think about what the root word is.

So the first word is unhealthy, which means to not be healthy.

I eat lots of burgers and chips, and this is unhealthy.

The second one is unfair.

I felt the decision that was made was unfair, unfair.

C is uncooked.

You can eat that vegetable uncooked, meaning not cooked.

And finally, untie.

Before taking my shoes off, I must untie the laces, untie.

So we have unhealthy, unfair, uncooked, untie.

Pause the video and have a go at writing these words now.

Off you go.

Great, so let's see how you've done then, team.

Some really, really great application of those root words and the prefixes there, good job.

The first word that we are looking at was unhealthy.

I've seen it written in these two ways.

That root word healthy has that strange L-L-L spelling, doesn't it? But it's an E-A.

I do remember that, and it's a Y at the end, too.

Remember that Root word's not going to change.

My root word is healthy.

H-E-A-L-T-H, so I'm just gonna add my prefix un, so it's gonna be unhealthy.

Remember our rule, when adding the prefix un, the root word doesn't change.

The next word was unfair.

Okay, this spelling of fair that I'm looking for is that idea of something being just.

The other spelling of fare, F-A-R-E is a word, it's a homophone, but that would be the fare that you would pay to go on a bus or a train.

That would be the ticket that you're buying.

So I'm looking for that fair, F-A-I-R spelling.

And remember when adding that prefix un, the root word is not going to change.

So the correct spelling is unfair, U-N-F-A-I-R.

Next one was uncooked.

Be careful with this, sounds like a t-t at the end, doesn't it? But it's not, it's our E-D suffix on the end, 'cause it's that past tense of the verb cook, and when we're adding then our prefix un, it's just gonna remain the same, that root word doesn't change, so it's uncooked, U-N-C-O-O-K-E-D.

And finally we had untie, and that word tie is that I-E spelling at the end.

I'm going to add my prefix un, my root word's not going to change.

So the correct spelling for untie is U-N-T-I-E.

Great, pause the video now share any successes, make any corrections, off you go.

So we are going to write a sentence containing some of our focus spellings now.

When we write the whole sentence, we need to do several things at once.

We need to remember the whole sentence.

We need to form our letters correctly.

We need to sound out each word.

We need to make sure we look out for common exception words, and we also need to remember sentence punctuation, capital letters, and full stops.

So just listen to me say the sentence first.

Yesterday, I felt so unhappy when I tried to undo the knot in my laces.

Yesterday, I felt so unhappy when I tried to undo the knot in my laces.

So we're gonna use some strategies now to help us remember this sentence.

First one is tapping it out.

You can do this in your head, your shoulders, on the table, on the floor.

I'll have a go first.

I find this really helps us to make sure that we get those syllables and those beats in the words, so we don't miss any sounds.

Yesterday, I felt so unhappy when I tried to undo the knot in my laces.

Yesterday, I felt so unhappy when I tried to undo the knot in my laces.

Have a go at tapping that out now and saying the sentence, pause the video.

Great, the next one is saying it in a silly voice.

Yesterday, I felt so unhappy when I tried to untie the knot in my laces.

Pause the video and say it in your silliest voice now, and see if you can make me laugh.

Brilliant, some really silly voices there.

And finally, counting the words on our fingers to make sure we don't miss any.

Yesterday, I felt so unhappy when I tried to untie the knot in my laces.

Yesterday, I felt so unhappy when I tried to untie the knot in my laces.

Pause the video and count out those words on your fingers now and say the sentence.

Good job.

So we're gonna have a good writing the sentence now.

Remember to sound out each word, think about any common exception words or any tricky words, and also remember to check your sentence punctuation, capital letters and full stops, and any other punctuation that might be in it.

I'll say the sentence one more time.

Yesterday, I felt so unhappy when I tried to untie the knot in my laces.

Pause the video, write that sentence.

Okay, great job everyone, some brilliant handwriting there, some great application of the prefixes that we've been looking at today, and some careful consideration of some of those trickier common exception words as well.

Also really impressed with seeing everyone with their punctuation, capital letters and full stops.

So let's see how you did.

Make any corrections as we go along.

Yesterday needs to have a capital letter, and also a comma after as well, because it's a sentence starter here.

I felt so unhappy.

So it's our root word happy there, and we've added our prefix un.

It's not changed the spelling of that root word.

When I tried to undo, un there, as our prefix ahead of the word do, undo.

So not to be done up.

The knot, watch out for that silent K there.

That K and the N are working as a digraph to make a nn, or N sound.

Knot in my sh laces, maybe you put shoe laces there as well, but don't worry if you haven't.

Shoe laces or laces, careful with that one.

Obviously we need to have a full stop at the end as well.

Brilliant.

What did you learn, what successes did you have? Did you make any magical mistakes that you can learn from? Pause the video, share your learning now, and make any corrections, off you go.

Excellent work today, everyone.

Today we've been looking at the prefix un.

A prefix is a letter or group of letters that we add to the starter word to create a new word.

The prefix un is added to the beginning of a word without changing the spelling of the root word, and the prefix un usually means not.

Keep up the great spelling everyone, I'll see you again soon.
