The teacher can indicate if your son has math problems as the scores indicate or if he is a solid math student as he believes. If the teacher is not available during the summer, a tutor or a commercial learning center should be able to discover any weaknesses your son has in math and develop a program to sharpen his skills.
Participation in activities this summer that require prolonged concentration should improve your son's attention span. Some good choices are games like Monopoly, dominoes, Yahtzee, and Hearts that will require your son to pay close attention to what is occurring in order to win as well as focus on developing a strategy. Encourage him to play them frequently. Other activities that build concentration include playing tennis, doing puzzles, reading for 30 minutes a day, building models, and learning keyboarding skills.
In order to retain what he has learned, your son needs to review the material more often. At the beginning of the school year, look over his school papers with him each day and have him tell you what he has learned. Also, help him organize all his homework, classwork, and tests and keep them in a binder so that he will be able to review them before quizzes and tests. He should also get in the habit of spending some time one day a week reviewing everything that he has done that week. All this reviewing will keep the material that he has learned fresh in his mind.
