Chapter-by-chapter lessons following the NCERT Class 9 mathematics textbook, Ganita Manjari.
There are 8 courses, one for each chapter: Orienting Yourself: The Use of Coordinates, Introduction to Linear Polynomials, The World of Numbers, Exploring Algebraic Identities, I'm Up and Down, and Round and Round, Measuring Space: Perimeter and Area, The Mathematics of Maybe: Introduction to Probability, Predicting What Comes Next: Sequences and Progressions. Together they hold 30 lessons. Every lesson explains the ideas in order, works through examples, and ends with practice questions and full answers. The examples and questions use our own numbers rather than the textbook's.
This is for students in Class 9 following the NCERT textbook Ganita Manjari, and for parents or tutors who want a second explanation of each chapter.
