🔟 Counting to 1,000

What you’ll learn

1. Counting Past 100Count forward past 100 within 1,000, handling the roll-over at each hundred.Numbers keep going past 100: 101, 102, 103, and on. Each hundred repeats the same ones-and-tens pattern, so 123 sounds like 'twenty-three' with a hundred in front. The tricky spots are the ends of hundreds, like 199 rolling into 200.
2. Skip to 1,000Skip count by 5s, 10s, and 100s within 1,000.Skip counting still works for big numbers. By 5s and 10s the familiar patterns keep marching along, and by 100s you take giant hops: 100, 200, 300. Just ten hundred-hops reach 1,000.
3. Backward and AnywhereCount forward and backward within 1,000 from any starting number.You can begin counting anywhere within 1,000 and go forward or backward. Counting down works one step at a time, and you must watch the hundreds boundaries — counting back from 300 gives 299.
