Measurement is

Modes of learning are as important as the content. High performance achieved through rote memorization is not preferred in evaluating the growth of the pupils. We use some procedures and techniques to collect data about pupil progress and growth to determine the extent to which these varied mathematical learning objectives have been achieved. 

Measurement of any aspect of an object or phenomenon is its quantitative description.

NOTE:

• Measurement refers to the process by which the attributes or dimensions of some object or phenomena are quantified.
• More precisely, measurement is defined as the assignment of numerals to objects or events according to rules.
• Assessment is a process by which information is obtained relative to some known objective or goal.
• Evaluation refers to the value judgement made on the phenomenon, taking into consideration the quantitative and/or the qualitative information collected on it over a particular period of time.

Hence, we conclude that measurement is a quantitative description.
