America Counts is a new initiative from the Federal Government to improve the math skills of children. It works the same as America Reads, with schools, after-school programs, libraries, etc., taking part as tutoring sites, though America Counts is for children preschool through the 9th grade. America Reads is for children preschool through the 6th grade.
If you are interested in tutoring math and/or reading, look for a tutoring position on the jobs page and see if the site is in need of math tutors. As a tutor for America Counts, you will be required to attend the same trainings as America Reads Tutors: an Overview Training Session, the Extended Training Workshop and one of the Special Topic Sessions. Other training and support will be provided by the site that has hired you as a math tutor. You also may tutor both reading and math if you choose.
Please visit the Federal Government's Department of Education web site for more information on America Counts.
