      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. You can read the review summary here. For monthly reviews and editorials about kids’ software, media, and games, subscribe to CTR . (Note: Motion Math has no commercial interest in CTR.)
