The three pages before this page are the ones to be copied for the activity.
After copying (and laminating if so desired) cut the dominoes apart on the lines
indicated by the arrows. Each domino is two rectangles wide and one rectangle
high.
The three pages after this page show how the equation, story, table and graph
match up.
It is suggested that only the table and graph OR the equation and statement
dominoes be used the first time the activity is completed with students. Add
the challenge of the using all four once they can successfully match with two.
Using only 2 will create a self-checking loop.
An additional activity would be to cut the dominoes apart into single cards and
match equation, story, table and graph as a team or an individual.

Linear Dominoes
Version1






Play with 2 people.
The starting game uses only the table and graph dominoes. The advanced game uses all the dominoes.
Lay chosen dominoes face up in front of both players.
Randomly choose one domino as the starting piece. Players take turns matching dominoes to either end.
Players must be able to justify their match to each other if questioned.
Game is done when all dominoes are matched. Should be able to create a loop.
Version 2




Game designed for 2 people.
Shuffle dominoes and place them face down near the players.
Each player randomly chooses three dominoes from the pile.
The player with the graph that is the closest to vertical randomly chooses one of his/her dominoes to start the game.
This domino is placed in the playing area.
 The Player 2 links one of his/her dominoes to either end of the one in play. If Player 2 has no domino to play, he/she
takes a domino from the pile and it is the end of his/her turn.
 The Player 1 plays a domino from his/her stack or takes another domino from the pile.
 The first player to put all of his/her dominoes on the board is the winner.
Suggestion: If students have never played dominoes, it may be beneficial to introduce them to the game of dominoes with
real dominoes before playing Linear Dominoes.
