I was one of the founders of the Math Learning Center (MLC) and have served on its Board of Directors since this 501(c)(3) organization started 40 years ago. During these 40 years, I have advocated for increased use of calculators and computers in math education. Several hundred of my math education and computer education publications are available free online (IAE, 2017). Three of my more widely read math education articles are (Moursund, 2017a; Moursund, 2017b; and Moursund, 2017c).
One of my contributions to the MLC was getting it started in developing some online Math Manipulatives programs (Moursund, 4/19/2013). A catalog of the MLC’s current collection of 11 free online math manipulatives is available (MLC, 2017).
