Content descriptor measure and compare objects using familiar metric units of length, mass and capacity, and instruments with labelled markings

Elaborations

• • Elaboration making a measuring tape using metric units of length and using it to measure and compare things; for example, the girth of a tree; explaining that the lines on a ruler show the beginning and end of each unit
• • Elaboration using a strip of centimetre grid paper to measure and compare the length of objects, connecting this with centimetre units on a ruler and using fractions of a graduation to give a more accurate measure
• • Elaboration discussing how the capacity of a container or object usually refers to the amount of liquid it can hold, measured in millilitres and litres; comparing the capacity of different sizes of familiar drinks; for example, 600 millilitres, one litre, 2 litre and 3 litre milk containers
• • Elaboration measuring and comparing the mass of objects and capacity of containers, using measuring jugs and kitchen or other scales and standard metric units of millilitres, litres, grams and kilograms; interpreting and explaining what the lines on the measuring jug or scales mean
• • Elaboration comparing the capacity of different beakers used in science lessons and using the numbered graduations to measure out different capacities of liquid
