## NCERT/CBSE Mathematics Courses - Class 6

Here is a list of all the mathematics courses that will be produced from each chapter of the class 6 book. Essentially, the contents of each chapter will be explained in a single course. As mentioned above, we might make slight changes to the list below while creating the courses, meaning that we might mix two or more chapter as or when necessary or possible but we will not disturb the natural flow of the material.

- Knowing our Numbers
- Whole Numbers
- Playing With Numbers
- Basic Geometrical Ideas
- Understanding Elementary Shapes
- Integers
- Fractions
- Decimals
- Data Handling (Statistics)
- Mensuration
- Algebra
- Ratio and Proportion
- Symmetry
- Practical Geometry
