OBJECTIVES:
 1) To compute expressions like (56 + a) + 4 and (50 * 7) * 2;
 2) To identify the commutative and associative properties;
 3) To rewrite expressions by using the distributive property;

MATERIALS:
 1) chalk                   
 2) blackboard
 3) electroboard
 4) response sheets
 5) pencils

STRATEGIES:
 1) Class discussion of understanding of terms commute, associate and
    distribute.
 2) Class discussion of dictionary meaning of terms commute, associate
    and distribute.
 3) Teacher blackboard demonstration of mathematical application of
    terms commutative, associative and distributive properties.
 4) Teacher demonstration of electroboard.
 5) Three-student-teams demonstration of electroboard.
 6) Class participation with response sheets.
