Add a Prefix!
Students will learn the meanings of various prefixes.
Introduction (5 minutes)
- Tell your students that they will learn about prefixes today.
- Ask your students if they know what a prefix is.
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."
- Tell them that "dis" and "un" mean not. Examples of words that contain these prefixes are "disorganized" and "undo."
- Tell your students that "mis" means wrong. An example of a word that contains this prefix is "misunderstood."
- Tell your students that "pre" means before. An example of a word that contains this prefix is "pretest."
- Write the meaning and examples of the prefixes on the board.
Guided Practice/Interactive Modeling (20 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 (30 minutes)
- Tell your students to each write ten 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.
- Enrichment: Ask advanced students to write stories that contain at least ten prefixes.
- Support: Ask struggling students to read a short storybook, then identify and write down all the prefixes in it.
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 (10 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.
