|What strategies are most useful in helping me develop algorithms for adding, subtracting, multiplying,|Absolute value is useful in ordering and graphing positive and negative numbers. |
|and dividing positive and negative numbers? |Computation with positive and negative numbers is often necessary to determine relationships |
|What properties and conventions do I need to understand in order to simplify and evaluate algebraic |between quantities. |
|expressions? |Models, diagrams, manipulatives and patterns are useful in developing and remembering algorithms |
| |for computing with positive and negative numbers. |
| |Properties of real numbers hold for all rational numbers. |
| |Positive and negative numbers are often used to solve problems in everyday life . |
