    Knowledge/skill statement 4
Uses number line to represent numbers
Related assessment item(s):
     Shows where 3/4 is on a number line (N4)

Determine the value of a point on a number line (N8)
Identify the graph of whole numbers less than 5 (N8)

Performance expectation(s):
    Uses number line to explore numbers less than 0 (M)

Represents numbers using models, such as number lines (P)

Uses concepts of negative numbers in concrete situations (e.g., on a number line) (C5)

Common Core Reference:
    3.NF.2; 3.MD.1; 6.NS.6; 7.NS.1
3.NF.2 Understand a fraction as a number on the number line; represent fractions on a number line diagram.

3.MD.1 Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a
number line diagram .

6.NS.6 Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative
number coordinates.

7.NS.1 Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram .
