Below are two different scenarios of how two friends, Alex and Jamie, are explaining their plans for a class project.

Scenario A:
Alex says, "For our project, we’ll first pick a topic, then gather information, make a presentation, and finally practice it before we present to the class."

Scenario B:
Jamie says, "For our project, we’ll pick the topic of ocean animals. Then we’ll go to the library on Thursday after school to check out three books about different kinds of ocean animals. After that, we’ll write notes about dolphins, whales, and sharks, make slides about their habitats, what they eat, and fun facts. Then we’ll take turns practicing the presentation three times before Friday."
