Unit 2: Integers (positive and negative numbers)
Unit 2: Integers and Rational Numbers (6 weeks)
2.1 I can locate and plot positive and negative numbers and their opposites on a number line. (7.1.1.3) 2.2 I can compare positive and negative rational numbers using <, >, =, =, =. (7.1.1.4) 2.3 I can add and subtract positive and negative rational numbers and use them to solve real world problems. (7.1.2.1, 7.1.2.2) 2.4 I can define absolute value and solve problems that use absolute value. (7.1.2.6) 2.5 I can locate and plot pairs of rational numbers (positive and negative) on a coordinate grid. (7.1.1.3) 2.6 I can multiply and divide positive and negative rational numbers and use them to solve real-world problems. (7.1.2.1, 7.1.2.2) 2.7 I can use the correct order of operations to evaluate numerical and algebraic expressions. (7.2.3.1, 7.2.3.2, 7.2.3.3) 2.8 I can generate equivalent numerical and algebraic expressions using associative, commutative, and distributive laws. (7.2.3.1, 7.2.3.3)
