Very light things, like this feather, have their weight measured in grams.

# Year 2 Measurements - Mass

This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with choosing and using appropriate standard units to estimate and measure mass (using kg/g).

Weighing accurately and choosing the correct unit to measure weight is an important skill and may take some practise. Children in Year 2 are taught to understand that the standard units grams are used for smaller items with less mass (or weight), whilst kilograms are used for heavier objects.

This quiz will help your child to choose the appropriate standard unit to measure mass or weight.
