Dividing Whole Numbers by Unit Fractions
Students will divide whole numbers by unit fractions and unit fractions by whole numbers, using visual models and the relationship between multiplication and division.
Key Questions
- Explain why dividing by a unit fraction is equivalent to multiplying by its reciprocal.
- Construct a visual model to show how many 1/3-cup servings are in 2 cups.
- Predict the outcome when a unit fraction is divided by a whole number.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
