What this chapter teaches.
Children count forward and backward from 100 to 200, learning that after 100 comes 101, 102, and so on, up to 200 — ‘double century’ meaning two hundreds. This chapter introduces the hundreds place informally (100 is 1 hundred, 200 is 2 hundreds) and has children compare numbers in this range and find what comes before/after/between given numbers, extending the skills from Class 2’s Fun with Numbers.

Activity 1 — Counting to 200.
Children count forward from 100 to 200 and backward from 200 to 100, either aloud or by filling in a number chart with some numbers missing.

Activity 2 — Before, After, Between (100-200).
Children find the number just before, just after, or between given numbers in the 100-200 range, the same skill practised in Class 2 but with bigger numbers.

Activity 3 — Comparing Numbers.
Children compare two numbers between 100 and 200 to say which is greater, using the hundreds digit first, then the tens, then the ones if needed.

Activity 4 — Reaching 200.
Word problems and counting activities that build up to the number 200 — for example, counting a collection of 200 objects in groups of 10 or 20.

Why This Chapter Matters

Comfortably counting and comparing numbers up to 200 is a stepping stone toward numbers up to 1000, which the House of Hundreds chapters (later in this book) build on directly using proper place value (hundreds, tens, ones).
