6-N-1-2
6.N.1.2 Compare and order positive rational numbers, represented in various forms, or integers using the symbols <, >, and =.
In a Nutshell
In this objective students have previous knowledge of comparing decimals using place value and comparing fractions and mixed numbers. Expanding on this knowledge, 6th graders will continue to compare and begin ordering rational numbers in different forms. Rational numbers can be expressed as a fraction, integer, terminating decimal, or as a repeating decimal. The comparison symbols < (less than), > (greater than) and = (equal to) are used to compare the value of two rational numbers.
Student Actions

Teacher Actions
|
-
Develop deep and flexible conceptual understanding of equivalencies among fractions, decimals and percents by comparing and ordering positive rational numbers on a number line or with pictorial representations.
-
Use previous knowledge to continue developing mathematical reasoning when determining where rational numbers fall on the number line.
- Develop strategies to compare rational numbers and integers using comparison symbols: <, >, =. ( e.g.: Students could use a number line to plot rational numbers, then compare by going left to right as least to greatest.)
|
-
Implement tasks that promote reasoning and problem solving by helping students develop these strategies for comparing and ordering positive rational numbers, including converting between fractions, decimals, and percents to compare value (See 6.N.1.4).
- Use and connect mathematical representations including both concrete, (e.g., fraction strips) and visual representations, (e.g.,grids, pictures, vertical and horizontal number lines), to guide as students visually compare positive rational numbers and integers.

Key Understandings
|
Misconceptions
|
- All rational numbers can be expressed as a fraction, integer, terminating decimal, or as a repeating decimal and can plot these on a number line.
|
- Students may think rational numbers can only be represented by terminating decimals.

Sample Assessment Items
|
|
The Oklahoma State Department of Education is releasing sample assessment items to illustrate how state assessments might be designed to measure specific learning standards/objectives. These examples are intended to provide teachers and students with a clearer understanding of how the state assesses Oklahoma's academic standards and their objectives. It is important to note that these sample items are not intended to be used for diagnostic or predictive purposes. Ways to incorporate the items.
