Understand a fraction as the quantity formed by parts of a whole

What you'll learn

1. Partition a whole (circle, rectangle, or other shape) into a specified number of equal parts and explain why the parts must be equal
2. Identify and name a unit fraction 1/b as one part when a whole is divided into b equal parts (e.g., 1/4 is one part when a whole is cut into 4 equal parts)
3. Explain the meaning of the numerator and denominator in a fraction a/b - the denominator tells how many equal parts the whole is divided into, and the numerator tells how many of those parts are being counted
4. Construct a non-unit fraction a/b by counting unit fractions (e.g., 3/4 means three copies of the unit fraction 1/4)
5. Determine the fraction represented by a shaded region in an area model and shade a region to represent a given fraction
