- Identify the two numbers to be compared.
- Use the greater than (>), less than (<), or equal to (=) symbols to compare the numbers.
- Write a complete statement to show the comparison. For example:

- Identify the numbers in the set to be ordered.
- Determine if you are arranging the numbers in ascending or descending order.
- Start with the smallest (or largest) number and arrange the numbers accordingly.
- Write the numbers in the chosen order, separated by commas. For example:
- If ordering in ascending order: 3, 6, 9, 12, 15
- If ordering in descending order: 20, 15, 10, 5, 0

- 7 ___ 9
- 15 ___ 15

- 12, 6, 9, 3, 18

- 25, 19, 30, 15, 22

Number and Operations (NCTM)

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Understand the place-value structure of the base-ten number system and be able to represent and compare whole numbers and decimals.

Algebra (NCTM)

Use mathematical models to represent and understand quantitative relationships.

Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.

Connections to the Grade 3 Focal Points (NCTM)

Number and Operations: Building on their work in grade 2, students extend their understanding of place value to numbers up to 10,000 in various contexts. Students also apply this understanding to the task of representing numbers in different equivalent forms (e.g., expanded notation). They develop their understanding of numbers by building their facility with mental computation (addition and subtraction in special cases, such as 2,500 + 6,000 and 9,000 - 5,000), by using computational estimation, and by performing paper-and-pencil computations.
