State an opinion and support it with one reason using the frame "I like ___ because ___."
An opinion is what you think or feel about something. "I like dogs" is an opinion. But a strong opinion needs a REASON, so people understand why you feel that way.
The frame "I like ___ because ___" is a simple tool. You name what you like, then tell why. "I like dogs because they are playful" tells both the opinion and the reason.
Mastery looks like: They state a personal opinion and support it with one real, specific reason using the "because" frame.
Common stumbles: Giving a reason that just restates the opinion, like "I like it because I like it."
