                    Addition and Subtraction of Integers 
                    Activity Overview 
                    In this activity, students investigate how addition or subtraction of integers is done using 
                    number line. 
                    Use the number line for adding and subtracting integers: 
                            Add a positive integer by moving to the right on the number line 
                            Add a negative integer by moving to the left on the number line 
                            Subtract an integer by adding its opposite

                     Multiplication of Integers--Repeated Addition and Subtraction 
                     Activity Overview 
                     In  this  activity,  students  investigate  how  repeated  addition  or  subtraction  is  related  to 
                     multiplication. 
                    Use number line to multiply integers 
                     Add a positive integer 2, 3 times (2 + 2 + 2) and observe the distance moved towards right 
                     side on the number line 
                     Observe this is the same as four times the integer (2 x 3) 
                     Similarly, add a negative integer three times 0 + (-2) + (-2) + (-2), this is the same as 3x - 2 
                     Compute (0 - 2 - 2 - 2) and notice that this is equivalent to - 3 x 2 
                     Compute 0 –(-2)– (-2)–(-2) and observe this is equivalent to - 3 x - 2 
                                                                         Examples:2 x 3 = 6 
                                                                                       
                      Multiplying is really just showing repeated adding. So, we need to add 2 three times. 2 + 2 + 
                                                                                   2 = 6 
                                                                                       
                                                                         Examples:-2 x 3 = -6 
                                                                                       
                       This one is asking us to add -2 three times. That means that we would have -2 + -2 + -2 = -6.

                                                                        Examples:-2 x -3 = 6 
                                                                                       
                                              This example says that we should add -2 negative 3 times.  
                                                                                       
                      The negative symbol as means "the opposite". So if we are going to add - 2 the opposite of 3 
                      times, we will move in the opposite direction on the number line. We had moved to the left, 
                                                                  so now we move to the right.

                     Division of Integers--Repeated Subtraction 
                     Activity Overview 
                     In  this  activity,  students  investigate  how  repeated  addition  or  subtraction  is  related  to 
                     Division. 
                    Use number line to divide integers 
                     Divide 14 by 7 
                     7 is subtracted repeatedly from 14 using the number line 
                                                                                                                                        
                     When 7 is subtracted 2 times from 14 in the number line, then we get the remainder zero. 
                     Thus, 7 is subtracted from 14, 2 times. 
                     Hence, 14 ÷ 7 = 2, 2 is the quotient.
