Print and cut out these cards Quadratic Substitution, or use the pre-prepared laminated cards your teacher gives you.

Die Card Snap

• Students play the game in pairs, threes or fours.
• Each player has a pile of the quadratic expression cards face down in front of them. One of the players rolls a die and then they each turn one of their cards face up.
• Each player uses the number on the die as the value for "x" in their equation (the teacher can decide if students are allowed to use calculators or not). The player whose expression is equal to 0 wins that hand.
• When all the cards are gone, the player with the most winning piles is the overall winner.

There are many games that can be played using these cards. Why not get students to create their own gameplay or set of cards? Below are two further examples:

Connect 4

• Students lay the cards out in a rectangle, face up. Each player can turn over one card at time by saying what "x" value will make the expression = 0. The first to get 3 or 4 in a row wins (Connect 3 or 4!).

Matching Pairs

• Students play in groups of four. All cards are dealt out. If two cards have the same "x" root then the student lays these on the table as a matching pair. When students have got rid of all their matching pairs, they take it in turns, starting from the dealers right and going round the table clockwise, to pick a card at random from their partner. If the new card makes a pair, they add it to their winning pile before offering their cards, blind, to the next player. When there are no cards left the player with the most matching pairs wins.
