Benchmarks for Number, Number Sense, and Operations

 

Benchmarks in this strand have been correlated to the Common Core State Standards (CCSS) for Mathematics for the Conceptual Category (CC), Domain (D), and Cluster (C).

NOTE: As a general resource for all Number Sense and Operations strand benchmarks, students and teachers might consult the following resources:

• Number and Operations from LearningMath.org contains 10 sessions each about 2.5 hours long with videos, online and print-based problem solving activities, interactive activities and demonstrations.

 

A.  Use scientific notation to express large numbers and numbers less than one.

CCSS: CC: grade 8, D: Expressions and Equations, C: Work with radicals and integer exponents.

B.  Identify subsets of the real number system.

C.  Apply properties of operations and the real number system, and justify when they hold for a set of numbers.

CCSS: CC: Algebra, D: Arithmetic with Polynomials and Rational Expressions, C: Perform arithmetic operations on polynomials.

D.  Connect physical, verbal and symbolic representations of integers, rational numbers and irrational numbers.

CCSS: CC: grade 8, D: Number System, C: Know that there are numbers that are not rational, and approximate them by rational numbers.

E.  Compare, order and determine equivalent forms of real numbers.

CCSS: CC: grade 7, D: Number System, C: Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.

CCSS: CC: grade 7, D: Expressions and Equations, C: Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

CCSS: CC: grade 8, D: Number System, C: Know that there are numbers that are not rational, and approximate them by rational numbers.

F.  Explain the effects of operations on the magnitude of quantities.

G.  Estimate, compute and solve problems involving real numbers, including ratio, proportion and percent, and explain solutions.

CCSS: CC: Geometry, D: Circles, C: Find arc lengths and areas of sectors of circles.

H.  Find the square root of perfect squares, and approximate the square root of non-perfect squares.

CCSS: CC: grade 8, D: Expressions and Equations, C: Work with radicals and integer exponents.

I.  Estimate, compute and solve problems involving scientific notation, square roots and numbers with integer exponents.

CCSS: CC: grade 8, D: Expressions and Equations, C: Work with radicals and integer exponents.
