Attribute Tiles Manipulatives

Plastic tiles in 6 colors, 3 shapes, and 2 sizes provide ample opportunity to test and teach attributes. Sorting activities increase from easy to hard: Cue redundant (multiple differences between objects), cue constant (only one variable), cue variable irrelevant (ignore irrelevant variables) and cue variable relevant, where all differences are important. Teachers can initiate patterns (AB, AABB, ABC) that students complete. Includes 180 plastic tiles, 12-compartment organizer, storage bin and instructions.
