What children learn in Level 49
- Welcome to Fraction Forest! A fraction names equal parts of a whole. This bar is cut into 4 equal parts.
- One of the 4 equal parts is one fourth. We write it 1/4. The bottom number says how many equal parts; the top says how many we mean.
- A fraction with 1 on top is a unit fraction: 1/2, 1/3, 1/4, 1/6, 1/8.
- The parts must be equal! This bar has 3 parts, but they aren't equal, so one part is not 1/3.
Georgia's K-12 Mathematics Standards:
- 3.NR.4.1 — Describe a unit fraction and explain how multiple copies of a unit fraction form a non-unit fraction. Use parts of a whole, parts of a set, points on a number line, distances on a number line and area models.
