A Task Rotation addresses the four learning styles as identified by Silver, Strong and Associates to differentiate the assignment. The 4 learning styles are Mastery, Interpersonal, Understanding, and Self-Expressive. Students will usually identify with two of the learning styles right away and thus feel empowered to complete the task assigned. This is a great way to get students engaged in a deeper look at concepts...in this case, two-step inequalities. :)
