Master Chapter 3 Class 6 - Number Play (Ganita Prakash) with comprehensive NCERT Solutions, Practice Questions, MCQs, Sample Papers, Case Based Questions, and Video lessons.
Start Learning NowSo far, we've used numbers to count, add, subtract, multiply, and divide. This chapter of your Class 6 Ganita Prakash textbook shows us that numbers can be much more than that—they can be fun!
We are going to look at the patterns hiding inside numbers, explore puzzles, and learn new ways to think about the numbers we see every day. This chapter is all about playing with numbers and discovering their secrets.
This chapter is full of games, puzzles, and fascinating number properties:
Puzzles and Games: We'll solve logic puzzles like "Supercells", where a number has to be larger than all its neighbors, and learn the winning strategy for number games like "21".
Number Properties: We will explore:
Digit Sums: Adding the digits of a number (like $6+8=14$) and finding patterns.
Palindromes: Numbers that read the same forwards and backward, like 363 or 121.
Magic Numbers: You'll discover the "magic" of Kaprekar's Constant, a special 4-digit number (6174) that you can reach by following a simple set of steps.
Unsolved Mysteries: We'll even look at a famous unsolved problem called the Collatz Conjecture, which is easy to understand but mathematicians still haven't solved.
Practical Skills: We'll also practice Mental Math shortcuts and learn how to make quick Estimations for real-life situations.
To make sure you understand every puzzle and trick, Teachoo has broken down each topic with clear, simple explanations and examples.
