Explain to learners that antonyms are pairs of words that mean the opposite of each other. This is very common with adjectives. Show the three examples; then ask learners to come up with three more pairs themselves. Check to make sure they are using adjectives.
Next, explain that antonyms can also be nouns. Ask learners to complete the list of five pairs. The solutions are in the next slide, but you can also accept alternatives. Ask if the learners notice any pattern (or lack of pattern) in the list of pairs.
In the next slide, explain that each of these pairs shows two distinct words that don't appear similar to each other, i.e. they are spelled very differently. However, in many cases, antonyms are very similar, and are formed using prefixes. Show the two example words and highlight the prefixes in red. Ask learners to think of any other examples.
Explain that these prefixes are used to show the absence or lack of the original noun, which is usually an abstract noun. Check to make sure learners understand this term and take time to explain if need be. The next activity is a mix-and-match. Have the learners copy the boxes and have a go at matching them individually before checking as a whole class. Drag the cards together to match and double click to separate.
To consolidate, ask learners to write a sentence using each word with a prefix. Compare with a partner and share the best with the whole class.
Explain to learners that there is another type of prefix that expresses opposite in a different way. All the ones they have previously seen simply denote the absence or lack of something. There is another prefix which also means that something is done wrongly or incorrectly. Show the leaerners the three example words and ask if they can add a prefix to change the meaning. Show the answers in the next slide (mis-). Ask learners to write a sentence using each word, using a dictionary if they need help with the meaning.
Next, explain that the same noun can take one or more prefixes, each of which slighly changes the meaning. Give the example of 'appearance' and how each prefix creates a different word and meaning.
Finally, ask learners to look at the two example words. For each one, add two different negative prefixes and write a sentence for each.
disease, unease
disinterest, uninterest

To understand the meaning of antonyms and how they are formed.
In the lesson on synonyms, we saw how words can have similar meanings. They can also be related through opposite meanings. This is very common with adjectives:
We call these pairs of words antonyms. Can you think of three other pairs of antonyms?
Nouns can also have antonyms. Complete the list of five pairs:
What do you notice about all these pairs of words? Do they have anything in common?
In the examples we've seen so far, the pair of antonyms are two distinct words. However, antonyms can also be formed by adding a prefix. For example:
Can you think of any other similar examples?
These prefixes denote the absence or lack of the original noun, usually an abstract noun.
In the next activity, match the appropriate prefix to the noun. Drag the prefix to the front of the noun card. You can double click them to separate.
Once you've finished, try writing a sentence with each word.
All the prefixes we've just seen denote the absence of something. However, there is another negative prefix that expresses oppositenes, but also that something is done wrongly, improperly or dishonestly.
What prefix can we add to these three words to create this new meaning?
Write a sentence using each of the words with the mis- prefix.
Some nouns can take more than one negative prefix with an accompanying change in meaning. For example:
appearance
Look at these two nouns. For each one, add two different negative prefixes and write a sentence for each.

Explain to learners that they will continue to look at antonyms, but this time by looking at adjectives. Make sure they understand these key terms by discussing the three example pairs.
In the next slide, show the learners the five sentences. Each sentence has a gap which can be filled with an adjective or its antonym. Have learners copy the sentences and fill the gap with two possibilities. Reveal the answers and accept any other reasonable options.
Remind learners that they have already seen how prefixes can be used to form antonyms. Use the two example sentences to explain how the same antonym can be formed in different ways.
Show the learners the four sentences in the next slide. Each sentence has an adjective that can be replaced by an antonym combined with a negative prefix. Ask learners to copy the sentences and think of a word they could use to replace each adjective. Use the 'Adjectives' button to reveal some possible solutions.
Feedback the answers and show the four possible solutions in the next slide.
Move on to the next slide. Explain these patterns that can help learners with the spelling of words with different origins. Have them copy down the rules.
Ask learners to copy down the list of 12 adjectives. For each one, they must add the appropriate prefix to form the antonym, and then write a sentence for both the original and antonym word. Once they've finished, encourage them to share their answers in pairs or small groups and feedback the best answers to the whole class.

To examine how adjective antonyms are formed and used.
Adjectives commonly have opposite words, or antonyms. When we think of an adjective, we often immediately think of its opposite. For example:
For each of these five sentences, write down the pair of adjective antoynms that could fill the gap.
Just like with nouns, adjective antonyms can be formed by using prefixes.
For example, we can write this sentence in two ways:
In the second example, we took the antonym of 'sad' and added the un- prefix.
Read these four sentences. Identify the adjective and replace it with an antonym and a negative prefix to keep the same meaning.
If you need a hint, click the 'Adjectives' button to see a list of possible antonyms.
kind, obedient, inspiring, experienced
Here are the sentences with some antonyms with prefixes you could use:
English uses several different prefixes to form antonyms. Here are some clues that help you know which one to use:
Keep these hints in mind in the next activity.
Add the correct prefix to the 12 adjectives. Next, write a sentence using each word.

Explain that this lesson will continue to focus on antonyms and prefixes, but this time by looking at verbs.
Check to make sure your learners know the meaning of these key terms. Use the two example sentences to help.
Show the learners the list of six verbs. Ask them to add a prefix to each one to form its antonym. Use the next mix-and-match activity to check answers as a whole class. Bring the cards together to connect and double click to separate.
Show the list of the correct answers on the next slide. Ask learners to write two sentences for each word, one for the original and one for the antonym. Ask learners to share their best sentences with the whole class.
Look again at the list of six verbs. Ask learners if they notice any difference between 1-2 and 3-6. Give your learners time to discuss and share their ideas.
Reveal the answer in the next slide. Explain that different prefixes change the meaning of the original word in different ways. Ask the learners to look at the nex tlist of verbs and to add the right prefix to make them reversative. Check answers on the next slide and ask learners to write pairs of sentence for each word.
Remind learners that they have already looked at the prefix 'mis-' in previous lessons on antonyms. Just like with nouns, we can add this prefix to show that something is done improperly or badly.
Ask learenrs to read the list of six verbs and to add the prefix 'mis-' to each one. Finally, ask learners to write a sentence for each word and its antonym. Share the best sentences with the whole class for feedback.

To examine verb antonyms, and how they are formed and used.
Antonyms are also very common with verbs.
Just like adjectives and nouns, they can be formed by adding a prefix.
1. I tied my shoes.
2. I untied my shoes.
Look at this list of six verbs.
What is the antonym for each one? Which prefix do we use to change it?
Match the appropriate prefix to the verb. Drag the prefix to the front of the verb card. Double click to separate.
Here are the correct prefixes. Write a sentence using the original word and its antonym.
Do you notice any difference in meaning between 1-2 and 3-6?
Not all prefixes change the meaning of the verb in the same way:
Examples 1-2 are negative. The simply mean the opposite of the original verb.
Examples 3-6 are reversative. This means the antonym denotes that the action was reversed or undone.
Here are some more verbs. Choose the right prefix to make them reversative.
Here are the correct prefixes. Write a sentence using the original word and its antonym.
Like with nouns, we can also use the prefix mis- with verbs.
E.g. to spell - to misspell
This prefix implies oppositeness, but also it also implies something else - what?
The prefix mis- implies that the verb was performed badly or wrongly.
Add the mis- prefix to these six examples, and then write a sentence for the antonym and the original word.
