Tiles can be easily (and cheaply) producedusing colored card stock or 3x5 cards.While positive tiles can all be one color, ora variety of colors, negative tiles should bered. Package the tile sets in sandwichbags and create enough sets so that eachstudent in the class has his/her own set.
An "enlarged" tile set with magnets on theback can be prepared for demonstrationsat the blackboard. Magnetic strips can befound in any craft department.
This is my class set of tiles which contains:positive tiles negative tiles

Many of the commercial versions of algebra tiles are made from plastic andpossess a "projectile" quality. These homemade tiles are seldom "airborne"since they are aerodynamically deficient. ;-)
