NCERT Solutions by EduGrown: Comprehensive Guide to Class 7 Mathematics (Ganita Prakash – Part II)
Welcome to EduGrown, your partner in navigating the latest NCERT curriculum. This guide covers the second installment of the Class 7 Mathematics series: Ganita Prakash-II.
Continuing the theme of the latest syllabus, this book focuses on higher-level arithmetic, advanced geometric constructions, and the foundational logic of algebra. Our solutions prioritize conceptual clarity, helping students connect mathematical theory to practical, real-world scenarios.
Chapter-wise Insights: The Ganita Prakash-II Curriculum
Chapter 1: Geometric Twins
An engaging introduction to Congruence. Students explore what it means for two shapes to be identical in size and shape, covering the congruence of line segments, angles, and triangles (SSS, SAS, ASA, and RHS criteria).
Chapter 2: Operations with Integers
Building on basic number sense, this chapter masters the four fundamental operations—addition, subtraction, multiplication, and division—specifically for negative and positive integers.
Chapter 3: Finding Common Ground
This chapter focuses on Data Handling and the concept of “Central Tendency.” Learn how to find the Mean, Median, and Mode to summarize data sets and make informed comparisons.
Chapter 4: Another Peek Beyond the Point
A continuation of decimal studies, focusing on the Multiplication and Division of Decimals. This chapter ensures students can handle complex calculations involving “the point” with speed and accuracy.
Chapter 5: Connecting the Dots…
An exploration of Visualising Solid Shapes. This section helps students understand the relationship between 2D sketches and 3D objects, introducing nets, vertices, edges, and faces.
Chapter 6: Constructions and Tilings
Geometry meets art. Students learn the precise use of a ruler and compass for Geometric Constructions and explore the fascinating world of Tessellations (Tilings)—patterns that cover a surface without gaps or overlaps.
Chapter 7: Finding the Unknown
The core of Linear Equations. This chapter teaches students how to set up equations for unknown values and solve them using transposition and balancing methods.
Frequently Asked Questions (FAQs) – Latest Syllabus
1. Why is the Class 7 Math book split into parts like ‘Ganita Prakash-II’?
The latest syllabus is designed to be modular. By splitting the curriculum, NCERT allows students to focus deeply on specific clusters of concepts—moving from basic number play in the first part to advanced operations and geometry in the second.
2. What is the significance of ‘Geometric Twins’ (Chapter 1)?
‘Geometric Twins’ is a student-friendly term for Congruence of Triangles. It is a critical foundation for higher geometry. EduGrown solutions provide visual proofs to make these criteria (like RHS and ASA) easy to visualize.
3. How does ‘Connecting the Dots’ help with 3D understanding?
This chapter uses Nets of Solids. By “unfolding” a 3D shape into a 2D pattern, students develop spatial reasoning skills that are essential for engineering and architectural concepts.
4. Is ‘Finding the Unknown’ related to the Algebra taught in Part I?
Yes. While Part I introduced algebraic expressions, Chapter 7 of Part II focuses on solving equations. It moves from representing a situation to actually finding the value of the variable.
5. How are ‘Learning Material Sheets’ used in Part II?
In this volume, the sheets focus on Constructions and Data. They provide graph templates and dot grids to help students practice symmetric tilings and data plotting directly.
