Flashdiscs by Wheel of Facts were designed by a 4th grade teacher to replace tradtional flashcards with colorful, plastic, double-sided discs.  This learning tool provides hours of self-checking practice and fun for children. Flashdiscs are made of a durable, high impact polystyrene and come with a lifetime warranty against breakage. The four basic sets cover Addition & Subtraction, Multiplication & Division, English/Spanish Translations and States, Abbreviations & Capitals.
