A math version of the game Hedbanz: Children hold number cards (1-10) to their foreheads facing away from themselves so others can see the card but they can't. Partners give clues about which number it is and the wearer has to guess. Hints can include odd or even, greater than, or less than. Fun reinforcement of number concepts; send pairs of fast finishers to play independently while you work with small groups. Printable number cards are included.
