Lesson Plan
Practice multi-digit multiplication and unit conversion with rates per minute, per day and per year.
Question: Ask what students spot and what they are curious about. Read “How many beats in one day?” aloud. Have each student guess and say why.
Question: Read “Whose heart beats more in a whole life?” aloud. Have partners explain their guesses to each other.
Big idea: Pause. Ask a student to say the idea in their own words.
Your turn: Have students try their own. Ask them to predict before they test.
