What This Standard Means
What Students Need to Do
- Students convert fractions with denominators of 10 or 100 into decimals and convert decimals back into fractions. They work with values below 1, mixed numbers, and fractions greater than 1.
What Mastery Looks Like
- Students correctly write 7/10 as 0.7, 43/100 as 0.43, and 125/100 as 1.25. They can also write 2.6 as 2 6/10 or 26/10.
Common Misconceptions
- Students may write 7/100 as 0.7 instead of 0.07. They may drop the whole-number part or use the wrong denominator when converting 1.24 or 2.6 to fractions.
How to Assess It
- Exit ticket: Write 1 7/10 and 126/100 as decimals, then write 0.48 and 2.3 as fractions with denominators of 10 or 100.

Ways to Teach It
Use two 10-by-10 grids to model 1.37, then label the model as 137/100, 1 37/100, and 1.37.
Ask students to explain why 7/100 equals 0.07, not 0.7, using a place-value chart.
Play a matching game with cards such as 9/10, 0.9, 134/100, 1.34, 2 6/10, and 2.6.
Give students a grocery receipt and have them rewrite prices such as $3.45 as 345/100 of a dollar and 3 45/100 dollars.
