Virginia SOL 7.NS.2

7.NS.2 is a Standards of Learning standard. These are the knowledge and skills expectations under it.

• 7.NS.2.a

  Use multiple strategies (e.g., benchmarks, number line, equivalency) to compare (using symbols <, >, =) and order (a set of no more than four) rational numbers ...

01

What Students Need to Do

Students decide which rational number is greater, less, or equal when the numbers appear in different forms. They order up to four values and explain their reasoning with conversions, benchmarks, or models.

02

What Mastery Looks Like

Students accurately compare positive and negative values written in different forms. They can order four values and defend the result with equivalent forms, benchmarks, or a number line.

03

Common Misconceptions

Students may think a negative number with larger digits is greater, such as claiming -8 is greater than -3. They may compare unlike forms without converting them, or treat 25% as 25 instead of 0.25.

04

How to Assess It

Ask students to order -1 1/2, -1.45, -140%, and -1.375 from least to greatest. Require two methods and a one-sentence justification.

1. 01

   Place cards labeled -3/4, -0.6, 25%, and 1 1/2 on a taped floor number line, then explain each placement.

2. 02

   Ask: Which is greater, -0.7 or -65%? Defend your answer using a benchmark and an equivalent form.

3. 03

   Play a four-card ordering race; teams earn a point only when every comparison symbol and explanation is correct.

4. 04

   Rank sale discounts labeled 1/4 off, 0.30 off, 20% off, and 35% off, then identify the best deal.

• 6.NS.1

  The student will reason and use multiple strategies to express equivalency, compare, and order numbers written as fractions, mixed numbers, decimals, and percen...

• 8.NS.1

  The student will compare and order real numbers and determine the relationships between real numbers.

• 6.NS.2

  The student will reason and use multiple strategies to represent, compare, and order integers.
