In these 10 lessons students use the number line to compare, order, add and subtract positive and negative integers. Students will be able to describe the Inverse Property of Addition, define absolute value and describe the Distributive Property of Addition and Subtraction. Students will use the Identity Property of Addition and the Commutative and Associative Properties of Addition to add two or more integers. They will be able to multiply and divide integers with the same and opposite signs and evaluate expressions using the Order of Operations and the Distributive Property of Addition and Subtraction. STUDENT WORKSHEETS, an EDUCATOR GUIDE, and a UNIT WRAP UP for assessing student performance after completing this unit are included.
