Grade 4 Unit 9 The Wonder of Fractions 3: Parts to Whole
In this final fractions unit, children move beyond comparing and adding fractions into the world of multiplying and dividing fractions. Through hands-on demonstrations, food-cutting activities, manipulatives, and guided practice, they’ll discover how fractions interact with one another and how these operations apply to everyday situations.
They Will:
- Review multiplying fractions using food models and games, then discover the “strategic trick” of multiplying numerators and denominators.
- Multiply fractions by whole numbers, connecting visual demonstrations to abstract math equations.
- Explore division of fractions, starting with concrete demonstrations (like sharing food) before learning the formal strategy of “invert and multiply”.
- Develop reasoning about why multiplying by a fraction makes numbers smaller and why dividing by a fraction can make numbers larger.
- Practice with story problems and games, applying their new skills flexibly.
- Connect math to cultural and personal identity through stories, discussions, and artistic reflections, keeping the learning imaginative and meaningful.
Children come to see fractions as dynamic and powerful: they don’t just describe parts of a whole but can be combined, scaled, and shared in endlessly creative ways. By mastering multiplication and division of fractions, they gain a lasting sense of confidence and wonder about the patterns hidden in numbers.
This purchase includes one digital curriculum unit with 15 days of lesson plans and 5 days of flexible projects. This unit will inspire you with beautiful images, clear instructions and exciting project ideas.
And that's not all. You will also gain access to the Wonder Hub, which includes supporting documents, videos, resources, and community.
