IN THIS UNIT, STUDENTS WILL BE EXPECTED TO:
 Add and subtract rational numbers.  Represent addition and subtraction using at least one method such as a horizontal/vertical number line or two color counters method.  Use words, visuals, and symbols to describe computational and realworld situations in which opposite quantities combine to make zero, incorporating the term additive inverse.  Explain, model, and apply commutative, associative, distributive, identity, and inverse properties to add and subtract rational numbers.  Apply the principle of absolute value in realworld contexts to describe the distance between two rational numbers on the number line.  Multiply and divide rational numbers.  Interpret products of rational numbers in reallife contexts.  Convert a rational number to a decimal using long division.  Identify terminating or repeating decimal representations of rational numbers.  Solve realworld and mathematical problems involving the four operations or rational numbers.  Use and apply order of operations to solve problems involving rational numbers. Students may use the attached documents to monitor their learning progress:
