What This Standard Means
What Students Need to Do
- Students change rational numbers among fraction, mixed number, decimal, and percent forms without changing their value. They use the form that makes a calculation or real-world comparison easier.
What Mastery Looks Like
- Students choose a useful form, convert it accurately, and keep its value unchanged. They use the converted number correctly in a calculation and can explain why the forms are equal.
Common Misconceptions
- Students may treat 0.666... as a rounded value instead of exactly 2/3. They may move the decimal in the wrong direction when finding a percent. Some multiply the whole number by the numerator, rather than the denominator, when changing a mixed number.
How to Assess It
- Exit ticket: A recipe is scaled by 1 2/3. Write this factor as an improper fraction, a repeating decimal, and a percent, then use it to scale 3/4 cup.

Ways to Teach It
Give groups fraction, mixed number, decimal, and percent cards to match, including 5/3, 1 2/3, 1.666..., and 166.666...%.
Ask students to explain why 0.333... equals 1/3 rather than being slightly less than 1/3.
Play a conversion relay where teams rewrite each number in two assigned forms and check the previous team’s work.
Compare store discounts, recipe scale factors, and sports statistics written as fractions, decimals, or percentages, then choose the most useful form.
