Developed by the Mixing in Math group at TERC, an education nonprofit, and based on research funded in part by the National Science Foundation, this book is packed with all kinds of math games for young minds. These projects and games, which use everyday materials such as paper towel tubes and cardboard boxes, can be used as icebreakers, party games, and group activities for indoors and out as well as special events throughout the calendar year. Whether in the car, on the bus, in a waiting room, or at the dinner table, the varied games and activates in this book serve as the perfect introduction to math for young children.
