Objective :  Students will be able to identify common prefixes  and suffixes and how they affect the meanings of those words. 

Do-Now:  Teacher will demonstrate a suffix and prefix pair.  For example a teacher writes something on the board, and then asks the students what they just did. They say : You just wrote something. Then the teacher writes the same thing again. What did I do this time?  You rewrote it. What did I originally do.  The word rewrite is an example of the base word write with the prefix re added to it, the prefix re means to do again. So when I add a prefix I change the meaning of a word. 

Mini-Lesson/ Guided Practice: (12 min.)What is prefix suffix.  Prefixes come at the beginning of a word and change the meaning of a base word. Suffixes come at the end of a word and change the meaning of that word.  Think of the word pre and how it means to pre-heat, pre-game.  Pre means before so the word prefix means before the word. 

Independent Practice: (10 min.)  Students complete a prefix suffix addition problem worksheet where they have to think of a base word and then add a prefix or suffix to make a new word poster.

Example:  prefix + root word = new word

                Suffix + root word = new word

     Then they must create a poster with 5 of each. 

Assessment: (3 min):  prefix suffix poster
