Numbers up to 1,200: their thousands, hundreds, tens and ones, reading them from words, finding 10 or 100 more or less, and comparing and ordering them.
Split the number by place: 1,146 is 1,000 + 100 + 40 + 6. To compare, look at the thousands first, then the hundreds, tens and ones.

Watch for: Writing one thousand fifty as 1,500. Changing the tens instead of the hundreds for 100 more. Thinking 999 is greater than 1,005 because 9 is big.
At home: Look at the price of something over $1,000, or a year, and ask: what's 100 more? 10 less? Which place changed?
