73 questions3 skills

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor.

27 questions1 skill

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values; use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

280 questions12 skills

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.

Number opposites

Distance between points: vertical or horizontal

Reflecting points in the coordinate plane

Missing numbers on the number line

Negative numbers on the number line

Points on the coordinate plane

Coordinate plane problems in all four quadrants

76 questions3 skills

Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.

76 questions3 skills

Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

150 questions7 skills

Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.

190 questions9 skills

Understand ordering and absolute value of rational numbers.

82 questions4 skills

Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram.

23 questions1 skill

Write, interpret, and explain statements of order for rational numbers in real-world contexts.

85 questions4 skills

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.

22 questions1 skill

Distinguish comparisons of absolute value from statements about order.

77 questions3 skills

Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
