Circulate and support students as they complete a short practice set with straightforward percentage questions.
Individually complete the practice problems and show work.
Review answers, address common errors, and connect percentages back to real health decisions.
Correct work, ask questions, and explain how they found their answers.
Summarize that percentages help us understand health information quickly and compare data fairly. Ask students to name one place they might see percentages in daily health life.
