This product helps to clarify the uses and differences between the two major parts of speech. Nouns and verbs are the most important of the eight parts of speech, because they are contained as the "actor" and the "action" in every sentence.
The worksheet, which I recommend using as an all-class activity, contains 15 sentences in which the same word is used both as a noun and as a verb. Students use two highlighter colors to mark the noun usage in one color, the verb usage in the other color. As they do this, the difference becomes clearer, and helps to teach the difference between "parts of speech" and "parts of a sentence." In other words, a word's part of speech is determined by its use in the sentence. This will help you teach this tricky concept to your elementary kids.
The answer key for page 1 could be projected, and kids might check their own papers.
On the practice page, we step it up a notch. With a new set of words, students are asked to write their own sentences like the ones on the worksheet. As they do this themselves, the concept is reinforced. (When the light bulb goes on, you'll know it!)
