Positive and Negative Integers 8 Day 2 Objectives: Students will 1. Subtract negative and positive integers 2. Create word problems and scenarios to describe problems with negative and positive integers 3. Explain why pairs of positive and negative chips can be added to help sol
of Integers using the chips. After using the number line to aid in adding integers, have students write general rules for adding and subtracting integers too large or too small to fit on the sample number line, for example, -14 35. Ask the students who are interested in football to describe how a football field is
