Number Play
About this chapter
Number Play is Class 6 Ganita Prakash chapter 3. Instead of new operations, it invites the learner to play with the numbers they already know, notice patterns, and build computational thinking. The chapter moves through twelve sections: numbers that describe situations (the heights-and-neighbours puzzle), supercells, patterns on the number line, digit counts and digit sums, palindromic numbers, Kaprekar's magic number 6174, clock and calendar patterns, mental math using boxed numbers, number patterns that add up cleverly, the unsolved Collatz conjecture, simple estimation, and the classic 21-game winning strategies. For CTET Paper 2 Mathematics, this chapter is tested through digit-sum reasoning, palindrome counting, Kaprekar steps, place-value comparisons, and short estimation problems. The four tests below — Practice 15 Q, Quiz 15 Q, Hard 15 Q, Mastery 30 Q — cover all twelve sections at the right depth.
