Virginia SOL 6.NS.2

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

• 6.NS.2.a

  Represent integers (e.g., number lines, concrete materials, pictorial models), including models derived from contextual situations, and identify an integer repr...

• 6.NS.2.b

  Compare and order integers using a number line.

• 6.NS.2.c

  Compare integers, using mathematical symbols (<, >, =).

• 6.NS.2.d

  Identify and describe the absolute value of an integer as the distance from zero on the number line.

01

What Students Need to Do

Students represent positive and negative integers with number lines, counters, drawings, and real situations. They identify, compare, and order integers, then describe absolute value as distance from zero.

02

What Mastery Looks Like

A student can model integers with counters, drawings, contexts, and number lines. They can identify plotted integers, order them correctly, use <, >, or =, and explain absolute value as distance from zero.

03

Common Misconceptions

Students may think a number with a larger absolute value is always greater, so they say -8 is greater than -3. They may reverse < and > or treat absolute value as making a number negative. Some count spaces rather than units when finding distance from zero.

04

How to Assess It

Exit ticket: Point A is three units left of zero. Name A, plot 2, compare A and 2 with a symbol, order A, -1, 0, and 2, then state |A|.

1. 01

   Use red and blue counters with a floor number line to model gains and losses, then label each ending integer.

2. 02

   Ask, "Which is greater, -3 or -7, and how does the number line prove it?" Students answer in two sentences.

3. 03

   Play integer card sort: students draw four cards, order them, add comparison symbols, and check their work on a number line.

4. 04

   Plot morning temperatures from four cities, order them coldest to warmest, and state each temperature's distance from zero.

• 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...

• 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 ...

• 7.NS.2

  The student will reason and use multiple strategies to compare and order rational numbers.

• 6.CE.2

  The student will estimate, demonstrate, solve, and justify solutions to problems using operations with integers, including those in context.
