Lesson Plan

Practice multiplying a fraction by a whole number by finding fractions of a fixed length.

1. Question: Ask what students spot and what they are curious about. Read “Which instrument should we hear next?” aloud. Have each student guess and say why.

2. Question: Read “How fast does half the string wiggle?” aloud. Have partners explain their guesses to each other.

3. Big idea: Pause. Ask a student to say the idea in their own words.

4. Question: Read “How long is 2/3 of 60 cm?” aloud. Ask a student who guessed differently to explain.

5. Big idea: Pause. Have partners explain the idea to each other.

6. Big idea: Pause. Ask how this idea connects to the last one.

7. Big idea: Pause. Ask a student to say the idea in their own words.
