I am supposed to teach a full year of College Algebra in only ten weeks as our academic terms have to be kept very short. Other than having students work on problem sets provided by the class worksheets in small groups toward the end of the lecture period, what other group activities can I incorporate? Again, time is a key factor (several chapters/concepts need to be covered and reviewed in the weekly 4-hour lecture), and the class sessions have been disrupted in the past for mandatory career development meetings for students. I would gladly appreciate any insight.
