In this unit students study the concept of absolute value in terms of symbols and representations on a number line.   Students then extend their understanding of addition and subtraction of rational numbers (i.e. positive and negative numbers, fractions, and decimals). Throughout the unit students are expected to apply integer operations in real-world contexts.

Essential Questions:
