RATIONAL NUMBERS
STANDARD: Apply algebraic order of 
operations and the commutative, associative, and 
distributive properties to evaluate expressions: 
and justify each step in the process. 
Student Objective:  
• Students will apply order of operations to 
solve problems with rational numbers and 
apply their properties, by performing the 
correct operations, using math facts skills, 
writing reflective summaries, and scoring 
80% proficiency

Rational Numbers
• A rational number is 
a real number that 
can be written as a 
ratio of two 
integers.
• A rational number 
written in decimal 
form is terminating 
or repeating.
