My review ( October 10, 2018):- Fundamental is the basic building block to learn and master any subjects. Forgot about advanced stuffs for a moment. First one must have to have a clear basic understanding about the subject one is going to learn. Same is true for mathematics too. Try to keep it simple.

To make children strong in mathematics first we should make them strong in basic stuffs of maths. One must have to have a basic understandings of mathematics such as arithmetic, basic geometry, elementary algebra etc. to learn the advanced stuffs. That's where school mathematics comes in. The roles of lower grade school mathematics is to teach and give clear understandings to the kids about very basic and fundamental stuffs.

Here my aim to review the primary school math books is similar. I am trying to find the better way to teach children. To improve the way we teach mathematics in school. To find a much better and effective solutions of teaching and learning mathematics.

Without farther discussion, let's dive into the topics the book has been covered.
1. Arithmetic
• 5 digit and 6 digit numbers
• Roman Numbers
• Arithmetic Operations (Addition, Subtraction, Multiplication, Division)
• Properties of Whole Numbers
• Fractions
• Decimal Numbers
• Estimating
2. Applications of Arithmetic
• Metric System
• Time and Calendar
3. Geometry
• Point, Line and Angle
• Polygons
• Geometrical Constructions
• Symmetry
4. Mensuration
• Perimeter and Area
5. Statistics
• Data Handling
