    S    tudents should be made ware that word parts called
         prefixes and suffixes can be added to words they already
    know. If students know the meanings of the prefixes and

    suffixes, they will be able to read and understand, and also
                                                                     After students are comfortable with several prefixes and
    write, many additional words.                                    suffixes, present further activities that include both

    Print these sentences on the board:

        Did you tie that package?                                    you read. Print help, pain, harm, less, and ful on five large

    Read the sentences aloud with students and ask if anyone         and ask a volunteer to give a word that makes sense made
    can figure out what un means in untied. Confirm that it          from any two of the five word parts in the sentence. Then

    something again.”                                                The two then stand back and you read the next sentence.
                                                                     There are many sentence possibilities, which might

                                                                     include the following:
    to base words, we get a new word with a different
    meaning—rename means “to name again,” unclean means                  My brother can’t swim. He is _______ in the water.
    “not clean,” etc.                                                    A broken arm can be very _______.
    Print a sentence on the board, leaving a space to the left
    of a base word where a student is to fill in the prefix un
    or re to fit the definition you give. For example, write
    They __loaded the truck, and ask for the word that means         Jeanne S. Chall and Helen M. Popp, Teaching and Assessing Phonics:
                                                                     A Guide for Teachers, available from Educators Publishing Service.
    the truck was not loaded (unloaded). Or ask for the word
    that means they had to load the truck again (reloaded).
    Another example: Write The cat was __wise to chase that
    chipmunk up the tree. Ask for the word that means the cat
    was not wise (unwise).

    Similar activities should be undertaken for suffixes. For
    example, print base words on the chalkboard and have
    the students read them aloud: rest, quick, thank, forget.
    Then print the suffixes less, ly, ful, and ness on the board.
    Point to the base word rest and ask students to add a
    suffix to it to make a word that means “full of rest.”
    Students should then print the suffixed word on their
    papers (restful). Do the same with the remaining base
