Convert Metric Measures
Children will use their skills of multiplying and dividing by 10, 100 and 1,000 when converting between units of length, mass and capacity. Children will convert in both directions e.g. m to cm and cm to m. Using metre sticks and other scales will support this step. They will need to understand the role of zero as a place holder when performing some calculations, as questions will involve varied numbers of decimal places.
