Though few students use them as more than a repository of homework problems, textbooks offer much more. The text surrounding the problems connects the material and offers students a chance to place the information in a framework they can understand. Like the shelves on a book shelf, they give the student a way to organize the material for greater understanding and greater retrieval. But reading math is difficult. Encourage your children to look to the text for explanations of what they don't understand.
Parents are understandably concerned about their children's math performance.
But this concern need not be transmitted through tension, anxiety, or frustration. Success will follow.
