Clap three times, pause, then clap three times again. What comes next? Three more claps.

Three claps, a pause, three claps — then what?

This is Chapter 1, Patterns in Mathematics, in your NCERT Maths book. Let's make it easy first.

What you will learn

  • A pattern is a rule. It tells you what comes next.
  • Number sequences. Add the same step, every time.
  • Shape numbers. Some counts make a neat square or triangle.
  • Odd and even. Pairing dots tells you which.
  • Growing shapes. A shape can grow by one rule.
  • Explaining why. A good guess is not yet proof.

  • Counting — matching amounts one to one.
  • Comparing — telling more, less, or equal.
