Arithmetic and algebraic computations should be carried out to solve the problem. In Problem One, the student has the equation’ x+ 2x= 42, 3x = 42, x = 14.
This is the step where we want to emphasize the reviewing, or reteaching if necessary, of the basic skills of mathematics. It is all too often that teachers try to introduce new material to their students only to find that the necessary prerequisites are lacking. We suggest that time be spent on pre tests or worksheets to determine whether or not the students have the necessary skills. For example, in Problem Two it may be necessary to review percentage and decimal skills.
