The Wright Ladies present to you a sort an task cards for the properties of real numbers. Students will be challenged to match the given examples with the properties that they represent. After learning to identify the properties, students will be asked to justify steps while simplifying using properties. The task cards challenge students to master their knowledge of properties through justification. This is an activity that can be used over and over again if printed on card stock and laminated. The sort can also be used for individual or small group practice.
