When reading, we all encounter unknown words at times. But how do we figure them out? In this lesson, students learn how to become a “human dictionary” by using a variety of strategies to figure out the meaning of unknown words.
Beyond just prefix identification, this meaty lesson taps into your students’ thinking. Using a combination of analogies, constructing, and deconstructing words with prefixes, students will learn the meaning and mechanics of prefixes.
When students learn the patterns and structures of words they become word wizards! They are able to more fluently convert a word from one part of speech to another, adjust the meaning, or translate a word from singular to plural (or vice versa). In this set of activities students will build on their knowledge of word structure and practice adding prefixes and suffixes, changing tenses and using contractions.
It is not only important for students to recognize words with prefixes, but also be able to choose the right prefix for the base word. In this lesson, students will work in groups to come up with as many words as possible with particular prefixes.
A prefix is something that is added to the beginning of the word to change its meaning. For example, adding the prefix “un” to “happy” creates a new word, “unhappy.” When students master the use of prefixes, their vocabulary increases tremendously. With our worksheets and resources, your students will learn how to use prefixes properly and improve their reading comprehension and writing skills.

A prefix is what is called an “affix”— an additional element placed at the beginning or end of a root, stem or word to modify its meaning. Another type of affix is a suffix, an element added to the end of the word. The four most common prefixes account for more than 95 percent of prefixed words. They are dis-, in-, re- and un-.
dis- (not or none): dislike, disappear, disagree, disconnect, disinfect
