MATHEMATICS (CLASSES XI –XII)

General Guidelines

(i) All concepts/identities must be illustrated by situational examples.
(ii) The language of ‘word problems’ must be clear, simple and unambiguous.
(iii) Problems given should be testing the understanding of the subject.
(iv) All proofs to be produced in a manner that allow the learner to see flow of reasons. Wherever possible, give more than one proof.
(v) Motivate results, wherever possible. Prove explicitly those results where a short and clear argument reinforces mathematical thinking and reasoning. There must be emphasis on correct way of expressing the arguments.
