What This Standard Means
What Students Need to Do
- Students rename tenths as hundredths by multiplying the numerator and denominator by 10. They apply the same reasoning to improper fractions and mixed numbers, using models to show equal values.
What Mastery Looks Like
- Students correctly write 7/10 as 70/100 and 13/10 as 130/100. They can show that 2 3/10 equals 2 30/100 or 230/100 using a model.
Common Misconceptions
- Students may change only the numerator or only the denominator, writing 13/10 as 13/100 or 130/10. They may also multiply the whole-number part of a mixed number by 10.
How to Assess It
- Give two blank 10-by-10 grids and ask: “Model 14/10, then write an equivalent fraction with 100 as the denominator.”

Ways to Teach It
Give pairs tenths strips and hundred grids to model 8/10, 12/10, and 1 6/10, then label matching hundredths.
Display 17/10 = 170/100 and ask students to explain why multiplying the numerator and denominator by 10 keeps the value unchanged.
Run a card sort matching tenths fractions, hundredths fractions, mixed numbers, and shaded hundred grids.
Use play money to show that 2 7/10 dollars equals 2 70/100 dollars and $2.70.
