Clock Wise provides playful practice in telling time to five-minute intervals. Players match an analog clock with the time it shows. The winner is the first to place all of his or her dominoes. The 48 dominoes are divided into four sets of 12 labeled A, B, C, and D. Clocks in Sets A and B show quarter hours and those in C and D display five-minute intervals. Combining two specific sets per game allows for three levels of play: quarter hour intervals, five-minute intervals, or both. Ideal for grades 5+. Bundle of 3 Clock Wise sets.
