1. Lesson 3-7 Dividing Integers Objective: To be able to divide positive and negative integers. Standard: Number Sense Indicator(s): N 5  Explain the meaning and effect of adding, subtracting integers N 6  Simplify numerical expressions involving integers and use integers to solve real-life problems. N 8  Develop and analyze algorithms for computing with percents and integers, and demonstrate fluency in their use.

2. You can divide any two numbers whether they are (+) or (-). Example -12 ÷ 6= ? Think, 12 ÷ 6 = 2. After you have completed your division, concentrate on the positive & negative signs. Here is the system for dividing integers… positive ÷ negative = negative negative ÷ positive = negative negative ÷ negative = positive positive ÷ positive = positive

3. Reminder: Integers are any whole number that is positive or negative. You can divide integers in an equation. So, -12 ÷ 6= -2 because… negative ÷ positive= negative
