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.
