I recently enrolled my child in an abacus program and the experience has been amazing. The techniques taught by the instructors at guruscool.com have proven to be very effective. My child's math skills have improved significantly. The company provides excellent support and resources for parents as well. I am very happy with the results and would highly recommend their programs.
