Name Use black cubes to represent positive integers and white cubes to represent negative integers. These patterns will help you add integers. A number and its opposite has a sum of zero. + + 1 + ( – 1) = 0 The sum of two positive integers is positive. + + 2 + ( + 1) = + 3 The sum of two negative integers is negative. + – 2 + ( – 3) = – 5 The sum of a positive integer and a negative integer will be positive or negative. + + + 2 + ( – 3) = – 1 + 3 + ( – 1) = + 2 Match pairs of black and white cubes to get sums of zero. Write the integers. Count to find the sum. 1. + ____________________________ 3. + ____________________________ 2. + ____________________________ 4. + ____________________________ 5.
