There is more to the operations of real numbers than students may think. Here is an activity that is fun and easy. Student work with a partner to examine what happens when they add, subtract, multiply and divide integers. Students use their solutions for writing a statement (rule) for positive and negative numbers. Students also get to experience what happens when they divide by zero. There are no right or wrong numbers to choose so students are able to discover and as the teacher you are able to facilitate and guide the students. It is a great way to build students' confidence in math and get a class discussion started!
