Students demonstrate they have the ability to: * Read and write numbers to 1,000 using base-ten numerals, number names, and expanded form. Example: 478 can be shown as four hundred seventy eight, 400 + 70 + 8, 4 hundreds, 7 tens, 8 ones
* Compare two three-digit numbers based on the meanings of the hundreds, tens, and ones digits using <, >, =. Example 578>345 or 345<578
* Mentally add or subtract 10 or 100 to or from a given number between 100 and 900.
* Decompose the three digits of three-digit number into hundreds, tens, and ones. Example: 567= 500 + 60 + 7
* Count within 1,000.
* Skip count by 5s, 10s, and 100s.
* Determine whether a group of objects (up to 20) has an odd or even number of members; if the total is even, write an equation to express the total as a sum of two equal addends. Examples: 4 + 4 = 8 or 10 + 10 = 20
* Students will recognize or recall specific vocabulary, such as: Base-ten numeral, compare, count, decompose, digit, expanded form, hundreds, number, number name, ones, skip count, tens, odd, even, mentally
