This offering from ed.gov, offers this comprehensive and downloadable kit on teaching math to your children. There are several activities to do at home, the grocery store, and on the go, as well as a glossary of related terms. In consideration of "our increasingly technological world," the foreward to this publication argues that, "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." While it hasn't always been easy in the past for parents to get involved with teaching math, this resource may be very helpful.
