Ankur got zero marks in a word problem on linear equations in an assessment. The teacher knows that he can solve linear equations correctly. The teacher ought to remark in his report

• Ankur has a problem in comprehending the language of the question, though he can solve the equations

• Ankur lacks concentration and hence has examination phobia

• Ankur is not studying and practising at home

• Ankur has not understood the concept of linear equations completely

In order to help the students with difficulties in remembering the geometrical terms and their meaning, a teacher must

• test students on definition of geometrical terms

• encourage group discussions

• stress on rote memorisation of all terms and definitions

• use lots of activities like preparing or solving crossword puzzles, jigsaw puzzles, etc

Problem-solving method is the

• teaching the development of mathematics within a historical, social and cultural context.

• cultivation of mathematical ingenuity, creativity and heuristic thinking by making students open-minded.

• gradual and systematic guiding through the hierarchy of mathematical notions, ideas and techniques.

• teaching of mathematical results, definitions and concepts by repetition and memorisation.

A method of teaching in which students work like a researcher and solve the problems.

• Inductive Method

• Deductive Method

• Project Method

• Heuristic Method

Appropriate method for establishment of the formulae in Mathematics is

• induction

• planning

• synthesis

• None of these
