Print, cut out and laminate playing cards.
Three players per game. One player is the team leader.
The team leader holds up a card to the other two players.
The first of the two players to correctly say if the shape is congruent
or similar wins that card.
If the players tie, the team leader hold up another card and the
winner of that round gets both cards.
The team leader plays the winner of each game and the loser now
becomes the team leader.
*Playing cards may also be used as a sorting activity into piles of
congruent or similar figures.
