NCERT Class 3 Maths Chapter 6 House of Hundreds – I: what it teaches

At a mela, children count torans, bangles and toffees past 200 and 300. The big idea: the same counting rules work every time; 298, 299, then a new hundred, 300. Hundreds, tens and ones tell you any number.

Why it matters later. Crossing hundreds confidently leads straight into numbers to 1000 in House of Hundreds – II.

You need

  • paper squares for hundreds
  • a long paper number strip

Tonight’s 10 minutes

  1. Guess how many beans in a big bowl. Count in tens, bundle tens into hundreds.
  2. Count on across a hundred: 296, 297, 298, 299, 300, 301.
  3. Write numbers on a paper tile path with gaps (211, 212, __, __, 215) for your child to fill.
  4. Ask “How many more to make 300?” for numbers like 250 and 280.
