Kilograms and Kilometres


Children focus on the use of the prefix ‘kilo’ in units of length and mass, meaning a thousand. They convert from metres to kilometres (km), grams to kilograms (kg) and vice versa. It is useful for children to feel the weight of a kilogram and various other weights in order for them to have a better understanding of their value. Bar Models or double number lines are useful for visualising the conversions.
