Class 9 can be called the foundation of higher classes and, therefore, the content of Class 9 Mathematics emphasises the in-depth understanding of concepts. Concepts like coordinate geometry, Heron’s formula, Euclid’s geometry and statistics are introduced in this grade while concepts like number system, triangles, areas and construction are extensions to the parts studied in earlier grades.

The content at this level aims that students must be able to relate the topics of Mathematics to real life and other subject areas. The emphasis is on enhancing the capacity of students to apply Mathematics in solving day-to-day life problems. In Learnflix, all the learning assets for grade-9 Math are developed to achieve this very aim.
