Tamilnadu board has implemented Trimester system. The entire academic year is divided into three segments. The examinations are conducted and students are evaluated at the end of each term independently. Previous term syllabus will be vomited and new syllabus will be introduced in each term.

Why mathematical learning is important?

Mathematics is a universal language. Studying mathematics will help to improve reasoning ability and analytical skills or thinking. Analytical thinking helps the child to deal with real life problems more logically.

Mathematics syllabus for class 9 under Tamil nadu board covers topics like – Set language, Real numbers, Algebra, Geometry, Coordinate geometry, statistics etc… Follow the link below for trimester wise syllabus.
