Domain - The Number System
Cluster - Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
[7.NS.A.2.d] - Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.
- Decimal number
Any real number expressed in base ten notation, such as 2.673. - Rational number
A number expressible in the form a∕b or – a∕b for some fraction a∕b. The rational numbers include the integers. - Repeating decimal
A decimal in which, after a certain point, a particular digit or sequence of digits repeats itself indefinitely; the decimal form of a rational number. - Terminating decimal
A decimal is called terminating if its repeating digit is 0. A terminating decimal is the decimal form of a rational number.
[7.NS.A.3] -
Solve real-world and mathematical problems involving the four operations with integers and other rational numbers.
[8.NS.A.1] -
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
[AII.A-APR.D.7] -
(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
[MIII.A-APR.D.7] -
(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
[PC.A-APR.D.7] -
(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
