Virginia SOL 3.NS.2

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

• 3.NS.2.a

  Compare two whole numbers, each 9,999 or less, using symbols (>, <, =, ≠) and/or words (greater than, less than, equal to, not equal to), with and without model...

• 3.NS.2.b

  Order up to three whole numbers, each 9,999 or less, represented with and without models, from least to greatest and greatest to least.

01

What Students Need to Do

Students compare whole numbers through 9,999 using place value, models, words, and the symbols >, <, =, and ≠. They order up to three numbers from least to greatest or greatest to least.

02

What Mastery Looks Like

Students compare numbers by checking thousands, then hundreds, tens, and ones as needed. They correctly use >, <, =, and ≠, and order three numbers in either direction, including numbers shown with models.

03

Common Misconceptions

Students may compare only the first digits they notice or assume the longer-looking model shows the greater number. They may reverse > and <, confuse least-to-greatest order, or overlook equality.

04

How to Assess It

Give students 4,092, 4,209, and 4,029. Ask them to order the numbers from least to greatest, then write a true comparison using two symbols.

1. 01

   Build two numbers with base-ten blocks or place-value disks, then compare them using a symbol card and explain the deciding place.

2. 02

   Ask, “Which is greater, 3,507 or 3,570, and which place proves it?” Students answer in writing with a comparison sentence.

3. 03

   Play Number Order Relay: teams draw three four-digit cards and arrange them from least to greatest, then reverse the order.

4. 04

   Compare attendance, distances, or book totals under 10,000, then rank three values and write two true comparison statements.

• 4.NS.2

  The student will demonstrate an understanding of the base 10 system to compare and order whole numbers up to seven digits. 

• 4.NS.1

  The student will use place value understanding to read, write, and identify the place and value of each digit in a nine-digit whole number.

• 2.NS.2

  The student will demonstrate an understanding of the ten-to-one relationships of the base 10 number system to represent, compare, and order whole numbers up to ...

• 7.NS.1

  The student will investigate and describe the concept of exponents for powers of ten and compare and order numbers greater than zero written in scientific notat...
