          Construction of a compound proposition from a truth table
          Teaching steps
             1.  Develop hands on activities that can be used to assist students
                 to construct compound proposition from a truth table. Assist
                 them  through discussion to identify  the  true  values  in the
                 last column  of a truth table.  Lead  them  to construct  basic
                 conjunctions for all true values in the last column.

             2.  Assist students through discussion to connect the conjunctions
                 by disjunction(s).
             3.  Use Example  2.26 in the Student’s Book to guide students
                 through discussion to construct compound proposition from
                 the given truth table.

             4.  Instruct  students  to  attempt  Exercise  2.8 in  the  Student’s
                 Book. Advise them to submit their work, check the correctness
                 of  their answers, and  provide  constructive  feedback where
                 necessary.
