## 4.NF.2Extend understanding of fraction equivalence and ordering.

### Numbers and Operations - Fractions: Domain

Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)

## 5.NBT.3bUnderstand the place value system.

### Numbers and Operations Base Ten: Domain

Read, write, and compare decimals to thousandths.

Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

## 6.NS.7aApply and extend previous understandings of numbers to the system of rational numbers.

### The Number System: Domain

Understand ordering and absolute value of rational numbers.

Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right.

## 6.NS.7cApply and extend previous understandings of numbers to the system of rational numbers.

### The Number System: Domain

Understand ordering and absolute value of rational numbers.

Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars.
