Standard 6.0 Knowledge of Number Relationships and Computation/Arithmetic

Students will describe, represent, or apply numbers or their relationships or will estimate or compute using mental strategies, paper/pencil or technology.

Topic

A. Knowledge of Number and Place Value

Indicator

Objectives
  1. Read, write, and represent rational numbers
    Assessment limit: Use exponential notation or scientific notation from (-10,000 to 1,000,000,000)
  2. Compare, order, and describe rational numbers with and without relational symbols (<, >, =)
    Assessment limit: Use no more than 4 integers(-100 to 100) or positive rational numbers (0–100) using equivalent forms or absolute value

Topic

C. Number Computation

Indicator

  • 1. Analyze number relations and compute
Objectives
  1. Add, subtract, multiply and divide integers
    Assessment limit: Use one operation (-1000 to 1000)
  2. Calculate powers of integers and square roots of perfect square whole numbers
    Assessment limit: Use powers with bases no more than 12 and exponents no more than 3, or square roots of perfect squares no more than 144
  3. Identify and use the laws of exponents to simplify expressions
    Assessment limit: Use the rules of power times power or power divided by power with the same integer as a base (-20 to 20) and exponents (0-10)
  4. Use properties of addition and multiplication to simplify expressions
    Assessment limit: Use the commutative property of addition or multiplication, associative property of addition or multiplication, additive inverse property, the distributive property, or the identity property for one or zero with integers (-100 to 100)

Indicator

Objective
  1. Estimate the square roots of whole numbers
    Assessment limit: Use whole numbers (0 – 100)

Indicator

  • 3. Analyze ratios, proportions, and percents
Objectives
  1. Determine unit rates
    Assessment limit: Use positive rational numbers (0 – 100)
  2. Determine or use percents, rates of increase and decrease, discount, commission, sales tax, and simple interest in the context of a problem
    Assessment limit: Use positive rational numbers (0 - 10,000)
  3. Solve problems using proportional reasoning
    Assessment limit: Use positive rational numbers (0 – 1000)

Note: Highlighted assessment limits will be tested in the no calculator section of MSA. In the assessment limit, (0-10) or (-10 to 10) means all numbers in the problem or the answer will fall within the range of 0 to 10 (including endpoints) or -10 to 10 (including endpoints), respectively. All content standards are tested in MSA but not all objectives. Objectives that have an assessment limit are tested on MSA. Objectives without an assessment limit are not tested on MSA.
