Add a Prefix!
Learning Objectives
Students will be able to identify prefixes, determine the meaning of words with prefixes, and use words with prefixes in sentences.
Introduction
(5 minutes)- Tell your students that they will learn about prefixes today.
- Ask your students if they know what a prefix is. Have them turn and talk to a partner, and then share with the whole group.
Explicit Instruction/Teacher modeling
(10 minutes)- Tell your students that a prefix is a word that is added to the beginning of a word and changes the meaning of the word.
- Explain that some examples of prefixes are re, dis, mis, un and pre.
- Tell them that "re" means again. An example of a word that contains this prefix is "retry." Explain the meaning of "try" and then the meaning of "retry".
- Tell them that "dis" and "un" mean not. Examples of words that contain these prefixes are "disorganized" and "undo." Explain the meanings of the words.
- Tell your students that "mis" means wrong. An example of a word that contains this prefix is "misunderstood." Explain the meaning of "understood" and show how it changes when the prefix is added. Discuss the meaning of the new word.
- Tell your students that "pre" means before. An example of a word that contains this prefix is "pretest." Ask a volunteer to help explain the meaning of the new word.
- Write the meaning and examples of the prefixes on the board. Ask students to restate the meanings of the examples to a partner.
Guided Practice
(15 minutes)- Pick a student and ask him to think of a word that has a prefix.
- Have the student come up and act out the word.
- Ask the rest of the class to guess the word and identify the prefix.
- Repeat the activity with the rest of the class.
- Write the words that the students act out on the board.
- Tell your students that they cannot act out a word that has already been done.
Independent working time
(15 minutes)- Tell your students to each write five sentences that contain a word that could be changed to a word with a prefix.
- An example could be, “I took a test yesterday." The sentence could be changed to, "I took a pretest yesterday."
- Tell your students to use each prefix at least once.
- Put students into partnerships and have them share their sentences. Prompt them to explain the meaning of the new word with the prefix and how it changed the sentence.
Differentiation
- Enrichment: Ask advanced students to write stories that contain at least ten prefixes. Have them write and illustrate the meanings of the words with prefixes.
- Support: Ask struggling students to read a short storybook, then identify and write down all the prefixes in it. Have them orally explain the meanings of the words with prefixes.
Assessment
(10 minutes)- Ask your students to identify and circle the prefixes on the Can You Find the Words with Prefixes? worksheet.
Review and closing
(5 minutes)- Divide your students into five groups.
- Assign each group a prefix and have them write as many words as they can that start with that prefix. Then, have them choose 1 to share with the class, sharing the meaning of the base word and then the meaning of the new word with the prefix.
