This book is a mathematics lab manual for Class 7 designed to help students learn maths in a hands-on, activity-based way rather than only through theory. It aligns with CBSE/NCERT guidelines and includes practical activities, experiments, and projects that cover key maths areas like arithmetic, geometry, mensuration, data handling, and basic algebra. Activities are explained clearly with diagrams and examples so students can observe, record, and discuss outcomes, enhancing their understanding of abstract concepts by doing them. Activities also include viva-voce questions and practice problems to reinforce learning and encourage thinking about real-life applications of mathematics.
