Lesson Overview
About this worksheet
Converting between fractions and decimals is an essential skill in fourth and fifth grade math. This worksheet builds fluency in both directions: students first practice writing common fractions such as halves, fourths, fifths, and tenths as decimals using the divide-the-numerator-by-the-denominator rule, then work in reverse to write familiar decimal values as fractions in simplest form. A reference box at the top of page 1 teaches both procedures using examples that do not appear anywhere in the assessed problems.
Section A presents 12 fraction-to-decimal conversions in a three-column grid, covering the most important benchmark fractions students encounter in upper elementary math and standardized tests. Section B presents 9 decimal-to-fraction reversals, reinforcing the inverse relationship. Section C closes with three context-rich word problems where students choose the appropriate conversion strategy, record their division work, and write a labeled answer.
The answer key on page 3 lists every correct response in the same two-column compact format used across the worksheet factory, so teachers can spot-check work quickly or students can self-assess after completing both student pages.
How to Use This Lesson
Read the reference box aloud and model one fraction-to-decimal conversion and one decimal-to-fraction conversion on the board before distributing.
Have students complete Section A independently or in pairs; circulate to confirm they are dividing numerator by denominator rather than guessing.
Discuss Section B as a class after students finish, emphasizing the need to simplify the resulting fraction completely.
Use the Section C word problems as a brief small-group discussion: ask students to identify which direction of conversion each problem requires before solving.
Use the answer key on page 3 for self-check, peer-check, or teacher spot-check; follow up with Equivalent Fractions Practice Packet for additional depth.
