This is a great way for students to learn their prefixes. Under each flap their is a list of words that uses each prefix. This is a good tool to have when students are writing. They could do this in their writing journals so when they are stuck they know where it is.
Exploring Affixes: Write the affix down. Give an example of a basic word with that affix. Eg. DIS - Dislike. As a class, figure out what it may mean and write down the definition. Students brainstorm examples of other words with those affixes and use dictionaries to see if there is a common meaning for the affix.
