NCERT Class 3 Maths Chapter 9 House of Hundreds – II: what it teaches

Birbal’s crow count leads to numbers up to a thousand. Your child shows three-digit numbers with hundreds tiles, tens strips and ones, places them on a number line, and compares them.

Why it matters later. Numbers to 1000 and comparing them are needed for 3-digit sums and for measuring in grams, metres and rupees.

Questions parents ask

How far do numbers go in Class 3?

Up to 1000.

Why is 0 needed in 504?

It shows there are no tens; without it the number would read 54.

How do I compare 947 and 974?

Same hundreds, so compare tens: 7 tens is more than 4 tens, so 974 is bigger.
