## Grade 2 Math: Comparing Numbers to 1000

### Comparing Numbers to 1000

In earlier lessons, students learned to determine which number is greater or smaller than another number, when the numbers are up to 100. In this lesson, they extend that knowledge to compare the size of numbers to 1000 using the symbols for greater than and less than.

Earlier they learned that a larger number is greater than another number if it comes after that number in the counting sequence. When two, three-digit numbers are compared and the first digit, in the hundreds place, is larger for one number, that number is the larger of the two.

In the problems in this lesson, students are given two numbers and must indicate which number is larger or smaller. They answer by writing the appropriate symbol.

### Counting: More or Less 101-100

In this lesson, students learn to determine what number is 1 or 2, 10 or 20, or 100 or 200 more or less than another given number, when the number given is a three-digit number. Special emphasis is given to numbers that result in a change from a lower decade to a higher decade, from a higher decade to a lower decade, from a higher hundred to a lower hundred, or from a lower hundred to a higher hundred.

### Make Numbers from Digits: 3 digits

In this lesson, students extend what they know about place value concepts to write numbers from digits. They are given three digits and are to write either the largest number possible or the smallest number possible from those digits.
