Children’s Technology Review has awarded Motion Math the Editor’s Choice Award for Excellence in Design in their October 2010 issue, giving us 4.5 stars! Warren Buckleitner, CTR’s editor, writes, “[Motion Math’s] ‘virtual manipulative’ technique can bridge the concrete and abstract…you move your way toward a better understanding of numerical relationships, one bounce at a time.” We’ve learned a lot about quality design principles from previous conversations with Warren, and we’re very honored with this award.
