What This Standard Means
What Students Need to Do

Common Misconceptions
- Students may multiply both numerator and denominator by the whole number. They may ignore units or fail to interpret an improper fraction in the situation.
How to Assess It
- Ask students to find the ribbon needed for 5 pieces that each measure 3/4 meter. Require an equation, model, and labeled answer.
