I made this presentation to review with my students what a noun is. It would also serve as an appropriate introduction to nouns. The file should be viewed as a presentation because of the animation involved. It starts with a concept attainment activity where students are shown words and asked to identify what they have in common. Therefore, don't tell students that they are learning about nouns when starting this. Let them discern that from the concept attainment activity where the "Yes" column contains people, places, and things. After that, students are given a definition of nouns, followed by a closer look at people, places, and things. On the things slide, students are encouraged to think about intangible things (feelings, ideas, etc.) as well as tangible ones. Lastly, students are presented with a few sentences and asked to identify the nouns in them.
