Following on from my last post, here is a nice game from TES who claim to be the largest network of teachers in the world? . Top Trumps Animals Algebra Substitution uses a set of 45 cards similar to the one shown below.
The Wikipedia entry states the rules as follows:
All the cards are dealt among the players. There must be at least two players, and at least one card for each player. The starting player (normally the player sitting on the dealer’s left) selects a category from his or her topmost card and reads out its value. Each other player then reads out the value of the same category from their cards. The best (usually the largest) value wins the “trick”, and the winner takes all the cards of the trick and places them at the bottom of his or her pile. That player then looks at their new topmost card, and chooses the category for the next round.
To generate the a, b & c values, dice or playing cards could be used.
