We know from research that children are more likely to be successful learners of any subject when parents actively support their learning. Today, helping children to make the effort to learn, appreciate and master mathematics is more important than ever. Our increasingly technological world demands strong skills in mathematics, not only in the workforce but also in everyday life, and these demands will only increase over the lifetimes of our children. To ensure that our children are ready for high school and on track for success in college and the workforce, parents must become involved early-and stay involved over the school years-to reinforce children's skills in and positive attitudes toward mathematics. Starting in elementary school, children should be learning beginning concepts in algebra, geometry, measurement, statistics and logic. In addition, they should be learning how to solve problems by applying knowledge of math to new situations. They should be learning to think of themselves as mathematicians-able to reason mathematically and to communicate mathematical ideas by talking and writing. Through the No Child Left Behind Act of 2001, President George W. Bush has made clear his commitment to the goals of raising standards of achievement for all children and providing all children with highly qualified teachers and instruction that is based on scientific research. Helping Your Child Learn Mathematics is part of the president's efforts to provide parents with the latest research and practical information that can help them both to support children's learning at home and to understand what they should expect from their children's schools. This publication includes a range of activities for families with children from preschool age through grade 5. These activities use materials found inside your home and also make learning experiences out of everyday routines, such as grocery shopping and doing laundry. The activities are designed for you to have fun with your child while developing and reinforcing mathematical skills. We hope you and your child will enjoy the activities suggested in this publication and develop many more of your own.
