Put the definition for whatever part of speech is being studied (such as "NOUN") on the board. Pass out a one- or two-paragraph text and have students label the page "NOUNS" and underline every noun with a pencil. Then, students highlight all the "person" nouns in 1 color, all the "place" nouns in another color, and all the "idea" nouns in another color, etc.

Additional Information:
This can be used to distinguish between singular/plural and common/proper nouns.

The replacement of nouns or verbs with more "vivid" ones using a thesaurus is a similar activity for a higher level (6.0 - 8.9).
