Dr. Don Crawford is a veteran classroom teacher and Special Ed teacher of many years, who developed the Rocket Math products to aid his students in mastering the four basic math operations of addition, subtraction, multiplication and division. He ultimately offered it to homeschooling families and they have experienced tremendous success and satisfaction! Dr. Don developed his former print formats into online, digital formats that can be downloaded and used immediately. He also offers an online Math Game version that takes advantage of the brain’s fertility in learning information in a fun setting requiring 10-12 repetitions of a fact to make a brain pattern versus 400 repetitions required in a rote setting. Feel free to contact Dr. Don with your questions and for guidance in teaching your child math. www.rocketmath.com • 503-298-8656 • [email protected]
