MA19-01
This lesson is coming soon.
In this lesson
Convert a terminating decimal to its equivalent fraction and back, and correctly order a mixed list of fractions and decimals by comparing true place value rather than counting decimal places.
What it covers
- Converting a terminating decimal to its equivalent fraction (using place value to find the denominator, then simplifying)
- Converting a fraction to a decimal (dividing numerator by denominator)
- Comparing and ordering a mixed list of fractions and decimals by converting them into the same form and comparing true place value
- Correcting the 'more decimal places = bigger number' misconception

For teachers
This GCSE Maths lesson teaches convert between fractions and terminating decimals, and order them. By the end, students should be able to convert a terminating decimal to its equivalent fraction and back, and correctly order a mixed list of fractions and decimals by comparing true place value rather than counting decimal places. It works through three worked examples and the mistakes examiners report.
