Big Ideas
- Fractions can be broken down (decomposed) in multiple ways into smaller parts with the same denominator.
- Concrete, pictorial, and symbolic models all provide ways to understand and demonstrate fraction decomposition.
Essential Questions
- How can a fraction be decomposed in more than one way?
- Why do we use concrete and pictorial models to represent fraction decomposition?
- What strategies help us find different ways to decompose a fraction into a sum of fractions with the same denominator?
- How do symbolic representations show our thinking when we break up a fraction into smaller parts?
- In what situations might decomposing a fraction be useful for solving math problems?
