Class 3 Maths Chapter 9 Revision Notes: House of Hundreds xe2x80x93 II

Chapter type: Numbers and early multiplication — extending place value toward 1000, and repeated addition.

Key ideas to remember:

1000 (one thousand) xe2x80x94 the number made of 10 hundreds; the next milestone after 3-digit numbers.

Ordering numbers xe2x80x94 arranging numbers from smallest to largest (increasing) or largest to smallest (decreasing).

Multiplication as repeated addition xe2x80x94 adding the same number multiple times, which can be written as a multiplication fact.

What you should be able to do after this chapter:

1. Count and recognise numbers approaching and reaching 1000.
2. Arrange a set of 3-digit numbers in increasing or decreasing order.
3. Rewrite a repeated addition (like 25+25+25+25) as a multiplication, and vice versa.

Remember: Multiplication is just a shorter way of writing repeated addition of the same number — seeing this connection clearly now makes memorising multiplication tables later much more meaningful.
