# Decimal fractions video

The video introduces examples of everyday situations that require more accurate measurements than using whole numbers.

The video includes examples of measuring in tenths and hundredths. We use a number line to represent and compare decimal fractions. Place value is extended to include tenths and hundredths. We relate decimal fractions to units of measurement, such as kilograms and grams, and centimetres and metres.

AC9M4N01
Recognise and extend the application of place value to tenths and hundredths and use the conventions of decimal notation to name and represent decimals

AC9M5N01
Interpret, compare and order numbers with more than 2 decimal places, including numbers greater than one, using place value understanding; represent these on a number line

AC9M4M01
Interpret unmarked and partial units when measuring and comparing attributes of length, mass, capacity, duration and temperature, using scaled and digital instruments and appropriate units

AC9M5M01
Choose appropriate metric units when measuring the length, mass and capacity of objects; use smaller units or a combination of units to obtain a more accurate measure

AC9M6M01
Convert between common metric units of length, mass and capacity; choose and use decimal representations of metric measurements relevant to the context of a problem
