Many principals have conducted work uscript writing and developmental mathematics.Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many i rting pupils' progress, can significantly aid in achieving a harmonious interplay between school and home.To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural paternal interest into productive channe ight be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and a Too often, however, teachers' conferences with parents are devoted to petty accounts of children's misdemeanors, complaints about laziness and poor work habits, and suggestion What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents' minds for the best utilization of the many hours that the child spends out of the classroom.
