While there are eight parts of speech, there only has to be one word the kids need to remember in order to be able to recall them. Taking the first letter of every part of speech and making it into either a word or a wacky sentence will make the words much easier to recall; for example, the parts of speech are "VNPAAPCI". This could be formed into "VAPNACIP" or "PIC AN AVP". It could also be, "Peter always prefers very cold nights in August." Simplifying the terms will make them easier to grasp and recall.
Choose eight volunteers in your class to represent each part of speech. The parts of speech may have a conversation with one another that symbolizes their significance; for example, the verb may interact with the noun, saying, "We (noun) go (verb) well together!" This will clear up the concepts and bring humor and fun into learning each of the parts of speech.
A quick, on-your-toes interactive game involves grouping the kids into a circle. There is a ball being passed around; one kid starts by holding the ball and then throwing it to a random person in the circle, yelling out one of the parts of speech. For example, "DOG!" The child should reply, "Noun". "THROUGHOUT!" The child should reply, "Preposition." If a child doesn't know or responds incorrectly or too slowly, he is "out" and eliminated from the circle. This game only works with children who have pretty well mastered the parts of speech.
Choose four volunteers from the class. Sit them up at a table with buzzers and set up a screen or overhead in front of them. Read off a sentence that also shows up on a slide; the word you want them to focus on will be highlighted. Whichever child buzzes first will get the opportunity to explain which of the eight parts of speech the highlighted word represents. If a child answers incorrectly, he gets negative points. Whoever gets the most points at the end of the timed game wins.
