Lesson Plan: Converting Fractions to Recurring Decimals Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to convert proper fractions into decimals, noting that the decimal expansion of a number either terminates or eventually repeats.
Objectives
Students will be able to
- convert proper fractions to terminating decimals by division,
- recognize repeating and recurring decimals and write appropriate notation for them,
- convert proper fractions to recurring or repeating decimals by division,
- solve word problems involving converting proper fractions to terminating and recurring decimals.
Prerequisites
Students should already be familiar with
- fractions and decimals,
- long and short division methods,
- rounding,
- converting fractions to decimals by rewriting the fraction to have a denominator of 10, 100, or 1,000 or by using multiples of unit fractions.
Exclusions
Students will not cover
- converting improper fractions or mixed numbers to terminating or recurring decimals,
- converting a terminating, repeating, or recurring decimal to a fraction,
- calculations with fractions and decimals, for example, multiplication.
