What this chapter teaches.
Children extend their place-value understanding toward 1000 (recognising that 10 hundreds make 1 thousand), continue practising 3-digit number comparison and ordering, and are introduced to multiplication as repeated addition (for example, 4 groups of 25 is 25+25+25+25 = 100), linking back to the grouping ideas from earlier chapters.

Activity 1 — Toward 1000.
Children explore numbers approaching 1000, understanding that 10 hundreds make 1 thousand, and practise counting up to and just past several hundreds (like 990, 995, 1000).

Activity 2 — Ordering 3-Digit Numbers.
Children arrange a set of 3-digit numbers in increasing or decreasing order, using the place-value comparison rules from House of Hundreds xe2x80x93 I.

Activity 3 — Multiplication as Repeated Addition.
Children see that repeated addition of the same number (like 25+25+25+25) can be written and thought of as a multiplication (4 groups of 25), previewing formal multiplication tables.

Activity 4 — Place Value Practice.
Further practice with expanded form and identifying place value in 3-digit numbers, reinforcing House of Hundreds xe2x80x93 I with new examples.

Why This Chapter Matters

This chapter completes the bridge from 3-digit place value to the very edge of 1000, and its introduction of multiplication as repeated addition is a crucial conceptual step before formal multiplication tables are memorised in later classes.
