Students use models to develop an understanding of the fraction as equal parts of a whole. Students use fraction models, names, and symbols to describe and compare fractional parts of whole objects, sets of objects, and points or distances on a number line. Students construct models of equivalent fractions.
Big Ideas:
- Fractions represent equal parts of a whole or a set of objects, and can be expressed as a/b.
- Fractions can be represented with models, names, and symbols.
- Fractions can be composed and decomposed into the sum of unit fractions.
- A fraction can be represented as a point on a number line between 0 and 1.
- Models can be used to show that fractions with different names can have the same value or represent the same part of a whole.
