What This Standard Means
What Students Need to Do
- Students represent fractions greater than 0 and up to 1 using equal parts. They use objects, drawings, strip diagrams, and number lines with denominators 2, 3, 4, 6, and 8.
What Mastery Looks Like
- Students build or draw a fraction with the correct number of equal parts and identify the selected parts. They place the same fraction accurately between 0 and 1 on a number line.
Common Misconceptions
- Students may count partition lines instead of equal parts when naming the denominator. They may accept unequal pieces or place fractions incorrectly on a number line.
How to Assess It
- Give students a strip divided into eight equal parts and a number line from 0 to 1. Ask them to represent 5/8 on both models.

Ways to Teach It
Give pairs fraction strips to fold into halves, thirds, fourths, sixths, and eighths, then shade a fraction named on a card.
Show two models of 3/4, one with equal parts and one with unequal parts, and ask students which is valid and why.
Play Fraction Match by pairing cards showing symbols, shaded strip diagrams, object models, and number-line points for the same fraction.
Use measuring cups to model fractions of one cup, then draw each amount as a strip diagram and mark it on a number line.
