  • Teacher Modeling

    will explain that knowing what parts of a word mean can help you understand the entire word. I will explain that some words have a prefix that can be used to help you identify the meaning of the word. I will introduce the prefixes un- (not), non- (not) and re- (back or again). I will show a chart of sentences (example is provided) and read the first sentence. (See Direct Teaching and Guided Practice Teacher Example Chart in Teacher and Student Materials below.) I will discuss the prefix of the bolded word and use this to figure out the meaning of the entire word. We know the word believable means that something is easy to believe. The word has un- before it, which is a prefix that means not. So I know that unbelievable means the speaker thinks something is difficult to believe. I will repeat this for sentences 2–4.

    TIP: Provide visuals of prefixes that explain their meaning. For example, provide a picture of a happy face with the word “happy” and a picture of a sad face with the word “unhappy”.

  • Think Check

    Ask: How did I determine the meaning of the unknown words? Students should respond that you looked at the prefix and root word separately and thought about the meaning based on the meaning of the prefix.

  • Guided Practice

    will read the remaining sentences on the chart and discuss the meaning of the prefix in each bolded word. We will use the prefixes to help us determine the meaning of the words.

  • Independent Practice

    will read the sentences on the independent practice worksheet and use the prefixes to determine the meaning of the words in bold. (Student Independent Practice is provided below.)
