This PowerPoint offer clues to a person that get more and more specific. There are about 3 clues per person (ex: football player, lifeguard, chef....). Each slide has a picture of the person (occupation) after all clues have popped up.
I use this as a quick engage in my 4th grade classroom or a brief brain break. The students write down their inferences on their whiteboards and have to justify their thinking.
