Algebraic Card Games

Student Voice: These are really cool Miss!

Why did I create Algebraic Card Games?

Firstly, Prime Climb has been very successful in creating a positive learning environment and the test results are great. Seeing students discussing mathematics whilst supporting each other and having fun is inspirational. In order for students to learn mathematics deeply and quickly they need to be relaxed, engaged and thinking flexibly. I hope these card games can enable the Tuakana-teina relationships to flourish in a fun, non-threatening way.

Secondly, student retention is an ongoing issue. For example, I find students can expand and factorize in class, but by the time the test comes along a number of students have forgotten what to do. The hope is that this fast paced, interactive game, might help retain their algebraic skills and terminology. Prime Climb certainly helps students retain the concepts of a Prime Numbers, and factors.

Feel free to print these cards and play with them.

The Trial Cards

These ideas for algebraic card games are just a resource, I will refine my play pedagogy over time. There is a focus on literacy, where players need to explain what makes their set a valid set, and if they use a Wild Card they need to say what it represents.

I am delighted with the quality of Make Playing Cards. I would like to compare the card quality and price with The Game Crafter. You can buy a set of my design if you like @ MakePlayingCards. The cheaper alternative is PDF printable cards, but I prefer 'real' cards.

I am collecting evidence of the effectivenes of these cards. If it works then more sets can be developed (number, percentages, geometry...) for different year levels and concepts. The sets could be designed in such a way that they could be combined and played with a large group of students.

The initial reaction has been very positive, but time will tell if this is a sustained interest. The professional cards are like 'candy crush' math, the students are excited and motivated to learn.

Students can create their own games. Snap is a safe starting place. Scaffolding is important. Below is a suggested game which students can modify to make it work.

Aim: To be the first to play all of your cards

Deal: Each player gets 7 cards.

The rest of the cards "the deck" are placed face down ready for players to draw on when it is their turn. Players put their "sets" face-up on the table before the first player picks up their card.

Turn: Pick up a card from the deck or discard pile, table your "sets", then discard a card face up on the discard pile.

Suggestion: If you have a set of three or more in your hand you must place it face-up on the table. If you can not make a move you pick another card from the deck. (Google Rummy and make your own rules).

All players can put cards on the table at anytime:

  • Valid ANY TIME Moves:
    • Place a set of three or more cards on the table.
    • Add to a set of cards which is already on the table.
    • Take one card from a set of four cards or more and use it immediately.
    • Take two cards from two different sets (with more than three members) and add a third to create a new set.
  • Example Moves:
    • A player puts a set of three cards on the table, one of the cards is wild.
    • Another player adds a fourth card to the set.
    • There is a race to grab the Wild Card, which must be used immediately.
      • Add the wild and a spare member of a tabled set to a card from your hand to complete a new set.
      • Combine the Wild with a set of two from a players hand.
  • Rules:
    • Sets can never have less than three members.
    • If you take a Wild card from the table you must play it immediately.
    • If you take a Non-Wild card from the table you can put it in your hand. (?)
    • Your turn starts when the previous player has discarded their card.
    • False Sets: If a player puts down a set which is not correct, the other players need to explain why it is not a set. The player then undoes their move, and does not get penalized. This means you need to watch for cheating, as there is an advantage if a player tables a False Set without being noticed.
    • You can adjust the rules to suit the players, by agreement before each round.

Equations & Graphs: 52 Cards:

  • 4 Wild Cards (Can be anything).
  • 4 Sets of Linear Relationships (16 Cards)
    • The Graph
    • The Equation in the form y=mx+c
    • The Equation in the form y-y1=m(x-x1)
    • The Equation in the form ax+by=c
  • 4 Sets of Parabolas (16 Cards)
    • The Graph
    • The Equation in expanded form.
    • The Equation in factorized form.
    • The Equation in completed square form.
  • 4 Sets of Circles (16 Cards)
    • The Graph
    • The Equation in (x-a)ˆ2+(y-b)ˆ2=rˆ2
    • The Equation in expanded form.
    • The Equation in standard form.

Extra Cards to make 68 Cards

  • 4 Sets of Exponentials (16 Cards)
    • The Graph
    • The Equation with y the subject.
    • The Equation with x the subject.
    • The Equation with the constant as the subject.

Other ideas for sets

  • Perhaps the standard graph of each set could be called a set.
    • y=x
    • y=xˆ2
    • xˆ2+yˆ2=1
  • Perhaps graphs with the same x intercept could be called a set?
  • Perhaps this could spark mathematical debate?
  • Tables could be added into the pack. Connecting tables, equations & graphs.

Linear Graphs: 60 Cards.

I made a set of card just with linear graphs and if these are successful I could make a quadratic/parabola set with a similar set up. After students have mastered the linear and quadratic set they could move on to the 'Equations & Graphs' set outlined above. I imagine building up lots of sets, and giving the students a set to play with based on their current skills.

Parabola Cards: 48 Cards.

This set is designed for students new to Parabolas. The focus is on locating the vertex and comparing the shape of multiple parabolas. A different set would be used to connect the equations to the graph.

The BIG pedagogical IDEA is that these cards could be used to practice reading coordinates. So students only snap if the vertex is the same. Then use them again later for paraobla shape, building the complexity.

Algebraic Manipulation: 52 Cards.

  • 4 WILD Cards
  • 4 Sets of four cards with two terms in expanded form: 16 GREEN
    • 8(a+b); 4(2a+2b); 8a+8b; 8b+8a
    • 12(a+b); 6(2a+2b); 12a+12b; 12b+12a
    • 16(a+b); 8(2a+2b); 16a+16b; 16b+16a
    • 20(a+b); 10(2a+2b); 20a+20b; 20b+20a
    • Fully Factored; Partially Factored; Expanded Alphabetical Order; Expanded Not Alphabetically ordered.
  • 4 Sets of four cards the three terms in expanded form: 16 RED
    • 8(a+b+c); 4(2a+2b+2c); 8a+8b+8c; 8c+8b+8a
    • 12(a+b+c); 6(2a+2b+2c); 12a+12b+12c; 12c+12b+12a
    • 16(a+b+c); 8(2a+2c+2b); 16a+16b+16c; 16c+16b+16a
    • 20(a+b+c); 10(2a+2b+2c); 20a+20b+20c; 20c+20b+20a
    • Fully Factored; Partially Factored; Expanded Alphabetical Order; Expanded Not Alphabetically ordered.
  • 4 Sets of four cards which are quadratics: 16 BLUE
    • xˆ2+7x+12; xˆ2+3x+4x+12; (x+3)(x+4); (x+4)(x+3)
    • xˆ2-x-12; -xˆ2-4x+3x-12; (x+3)(x-4); (x-4)(x+3)
    • xˆ2+x-12; xˆ2+4x-3x-12; (x-3)(x+4); (x+4)(x-3)
    • xˆ2+7x-12; xˆ2-3x-4x+12; (x-3)(x-4); (x-4)(x-3)
    • Expanded & Simplified ; Expanded; Factored.
  • Within the sets you can see the connections horrizontally and vertically, so within a colour the sets can be formed in different ways.
  • Connecting cards from different sets can be done with Wild Cards:
    • A Player could table a wild card with 8(a+b) and 8(a+b+c) and explain the wild card represents 8(a+b+c+d) as the next one in the pattern.
  • When a set is placed on the table the player must state what makes them a set. For example:
    • Set placed on the Table: 8c+8a+8b; 12c+12b+12a; 16c+16b+16a; 20c+20a+20b
    • Explain: Each card has an a, b and c term, which are not alphabetically ordered.
    • The members of a set only have one significant difference
        • Only the numbers are different (the format, signs and variable order is the same)
          • format of fully factored is not the same as partly factored
          • format of expanded and simplified is not the same as expanded
        • Only the signs are different (the format, numbers and order is the same)
        • Only the format is different (they are equivalent expressions)

Examples of Sets

Full Set of 2 variable expressions partially factored.

Full set of equivalent expressions

Creative set using a wild card

Example of a creative set of three using a wild card.

What expression would be next in this pattern? When a player uses a wild card they need to explain what the card represents:

8(a+b+c+d)

4 Variable expression.

Minimum Set Size = 3

Wild cards can be used to complete a set. If a player has a card that belongs in the set they can put their card down and take the wild card.

8a+8b+8c

8c+8b+8a
