1st Class Mathematics Measurement Length, Weight and Capacity Measurement

MEASUREMENT (Length, Mass, Capacity)

Synopsis

• Things are measured to find out how big or how heavy they are.
• The distance between two points is called length.
• Words used for length:

(a) Height-length measured upwards.   

(b) Distance - length measured between objects on same level.

(c) Width - length measured from side to side.

(d) Depth - length measured downwards.

• Length of an object can be measured by comparing it with the length of a known object, or a ruler.

• The heaviness of an object is called mass, which is usually called weight.
• Weight of an object can be measured by comparing it with the weight of a known object or a scale.

• The amount of space inside an object is called capacity.
• Capacity of an object can be measured by comparing it with the capacity of a known object or a measuring jar.
