Exploring Prefixes: Changing Word Meanings – Define prefixes – Prefixes are word parts added to the beginning to alter meaning – Common prefixes: un-, dis-, in-, im-, non- – ‘un-‘ means not, ‘dis-‘ means opposite, ‘in-‘ and ‘im-‘ mean not, ‘non-‘ means not or without – Prefixes alter word meanings – ‘happy’ to ‘unhappy’ shows how ‘un-‘ changes the meaning to its opposite – Practice with examples – Find words with these prefixes, discuss how the meaning changes | Introduce the concept of prefixes to students, explaining that they are groups of letters placed before the root of a word to adjust its meaning. Provide examples for common prefixes such as ‘un-‘, ‘dis-‘, ‘in-‘, ‘im-‘, and ‘non-‘, and discuss how each one alters the word it precedes. For instance, ‘un-‘ can change a positive word to negative, as in ‘known’ to ‘unknown’. Encourage students to think of additional examples and consider how the meaning shifts. This will help them understand the power of prefixes in language and enhance their vocabulary skills. Prepare a few exercises where students can practice identifying and using these prefixes in different words.

Exploring the Prefix ‘un-‘ – ‘un-‘ means ‘not’ or ‘opposite’ – Example: happy ’ unhappy – ‘unhappy’ means not happy – Discover more ‘un-‘ words – We’ll search for words starting with ‘un-‘ – Understand ‘un-‘ usage – Learn how ‘un-‘ changes word meaning | This slide introduces the prefix ‘un-‘ and its function to indicate negation or opposition. Start by explaining the definition of prefixes and how they alter the meaning of root words. Use ‘happy’ and ‘unhappy’ as a clear example to show how ‘un-‘ transforms the word into its opposite. Engage the class in an interactive activity where they find and share words that begin with the prefix ‘un-‘. This will help them understand how common this prefix is and how it’s used to change the meaning of various words. Encourage students to think of ‘un-‘ words in their writing to express negation effectively.

Exploring the Prefix ‘dis-‘ – ‘dis-‘ means negation or separation – Example: agree ’ disagree – ‘disagree’ means not to agree – Find ‘dis-‘ words in class activity – Think of words like ‘dislike’ or ‘discover’ – Understand how ‘dis-‘ changes meaning – ‘dis-‘ can turn a word into its opposite | The prefix ‘dis-‘ is a powerful tool in the English language that alters the meaning of a word to indicate negation or separation. For example, when we add ‘dis-‘ to ‘agree’, it becomes ‘disagree’, which means not to agree. During the class activity, encourage students to brainstorm and list out as many ‘dis-‘ words as they can, such as ‘dislike’, meaning not to like, or ‘discover’, meaning to find out something that was hidden or unknown. This exercise will help them understand how prefixes can change the meaning of base words and enhance their vocabulary. Provide guidance and support as needed, and ensure that each student participates in the activity.

Understanding Prefixes: in- and im- – ‘in-‘ and ‘im-‘ mean ‘not’ – Example: ‘correct’ to ‘incorrect’ – ‘incorrect’ signifies not correct – ‘im-‘ used before ‘p’ or ‘b’ – ‘im-‘ precedes words starting with ‘p’ like ‘imperfect’ – ‘possible’ becomes ‘impossible’ – Changes ‘possible’ to mean not possible | This slide introduces the prefixes ‘in-‘ and ‘im-‘ which are commonly used to negate the meaning of a word. It’s crucial for students to understand that ‘in-‘ is used generally, but ‘im-‘ is specifically used before words that start with the letters ‘p’ or ‘b’. Provide additional examples such as ‘impatient’ or ‘imbalanced’ to reinforce the rule. Encourage students to think of other words that follow this pattern and to be mindful of these prefixes when reading or writing. This understanding will enhance their vocabulary and comprehension skills.

Understanding the Prefix ‘non-‘ – ‘non-‘ means ‘not’ or ‘without’ – Example: toxic ’ nontoxic – ‘nontoxic’ means something that is not poisonous or harmful – Create a list of ‘non-‘ words – Think of words like ‘nonfiction’, ‘nonprofit’, ‘nonsense’ – Discuss the meaning of each – How does ‘non-‘ change these words? | This slide introduces the prefix ‘non-‘ and its meaning. Start by explaining that ‘non-‘ is a common English prefix that negates the word it precedes. Provide the example ‘nontoxic’ to illustrate how ‘non-‘ changes the meaning of ‘toxic’ from harmful to not harmful. Encourage students to brainstorm and list words that start with ‘non-‘ as a class activity, fostering collaborative learning. Discuss the new meanings of these words with the class to ensure understanding. This activity will help students recognize patterns in word formation and enhance their vocabulary.

Understanding Context: Prefixes in Action – Use prefixed words in sentences – Example: ‘unhappy’ means not happy. ‘She felt unhappy after losing her toy.’ – Context affects meaning – ‘Incredible’ can mean unbelievable or amazing, depending on the sentence. – Group activity: sentence creation – Work together to write sentences using words with prefixes like un-, dis-, in-, im-, non-. | This slide aims to teach students how the addition of prefixes like un-, dis-, in-, im-, and non- can alter the meaning of root words. Students should use these prefixed words in their own sentences to understand how context can change their meaning. For the group activity, divide the class into small groups and assign each group to come up with sentences using a list of new words with different prefixes. This will help them grasp the concept of context and how it influences the interpretation of words. Encourage creativity and sharing among groups to foster a collaborative learning environment.

Exploring Prefixes in Literature – Discovering prefixes in texts – Look for un-, dis-, in-, im-, non- in your reading – Authors’ use of prefixes – Prefixes alter the meaning of base words to express negation or opposition – Individual activity: Find prefixed words – Read a paragraph and highlight words with prefixes – Understanding word meanings with prefixes | This slide aims to help students recognize and understand the use of prefixes in literature. Encourage them to actively search for words with the prefixes un-, dis-, in-, im-, and non- while reading. Discuss how authors use these prefixes to change the meanings of words, often to indicate the opposite or absence of something (e.g., ‘unhappy’ means not happy). For the activity, provide a paragraph and ask students to identify and underline all the words with prefixes. This exercise will enhance their vocabulary and comprehension skills. After the activity, discuss as a class how the prefixed words contribute to the overall meaning of the text.

Class Activity: Crafting Words with Prefixes – Create words with prefixes un-, dis-, in-, im-, non- – Share your new words and meanings – For example, ‘happy’ becomes ‘unhappy’ with ‘un-‘ – Discuss prefix impact on base words – How does ‘dis-‘ affect ‘agree’ to form ‘disagree’? – Reflect on the activity and learnings | This activity is designed to reinforce the students’ understanding of the prefixes un-, dis-, in-, im-, and non-. Have the students use these prefixes to create new words from a list of base words provided. They should then share their new words with the class, explaining the meanings. Facilitate a discussion on how the addition of a prefix can alter the meaning of the base word, often creating an opposite or negative. This will help students grasp the concept of prefixes and their powerful role in language. Possible variations of the activity could include working in pairs, creating a word wall, or even a prefix challenge game.

Review and Practice: Prefix Power – Recap: un-, dis-, in-, im-, non- – Review the meaning of each prefix and how they change a word’s meaning. – Complete the practice worksheet – Apply what you’ve learned to reinforce your understanding. – Fun quiz next class! – Get excited for a game-like quiz to test your knowledge! – Keep practicing at home | This slide is aimed at reinforcing the students’ understanding of the prefixes discussed in today’s lesson. Start with a quick recap of the prefixes un-, dis-, in-, im-, and non-, and discuss a few examples for each to refresh their memory. Distribute the practice worksheet and guide students through the first few questions, ensuring they grasp the concept of how prefixes alter the meanings of root words. Inform them about the upcoming quiz to motivate them to study these prefixes. Encourage them to create their own examples at home for additional practice. The quiz will be designed to be engaging and interactive to maintain their interest in the subject matter.

Wrapping Up: Prefixes and Homework – Recap on prefixes un-, dis-, in-, im-, non- – Homework: 5 words with prefixes in sentences – Find words like ‘unhappy’ or ‘dislike’ and craft sentences – Reminder: Study for prefixes and suffixes quiz – Understanding the impact of prefixes – Prefixes change the meaning of root words, often to the opposite | As we conclude, remind students of the importance of prefixes in altering the meanings of root words. For homework, they should find five new words that include the prefixes discussed and use them in original sentences. This will help reinforce their understanding and prepare them for the upcoming quiz on prefixes and suffixes. Encourage them to think creatively and use context to form their sentences. During the next class, review the homework and clarify any misunderstandings before the quiz.
