In this unit, students are introduced** **to the concept of fractions and how they can be compared. (Mastery is not expected until grade 5.) Students will:

- compare fractions by using concrete models.
- compare fractions by using benchmarks.
- order fractions by using concrete models, benchmarks, and parallel number lines.
- explore fair-sharing situations with unit fractions.

How are relationships represented mathematically?

How can mathematics support effective communication?

How is mathematics used to quantify, compare, represent, and model numbers?

What does it mean to estimate or analyze numerical quantities?

What makes a tool and/or strategy appropriate for a given task?

**Denominator**: In a fraction, the number or quantity below the fraction bar. Tells the number of equal parts into which a whole is divided.**Fraction**: Notation used to represent part of a whole or part of a group by telling the number of equal parts in the whole (denominator), and the number of those parts being described (numerator).**Inequality**: A mathematical sentence that contains a symbol (<. >, ≤ , ≥, or ≠) in which the terms on either side of the symbol are unequal.**Mixed Number**: The sum of a whole number and a fraction.**Numerator**: In a fraction, the number or quantity above the fraction bar. Tells the number of parts of a whole being described.**Unit Fraction**: A fraction with a numerator of 1.
