Abstract

The invention provides one or more question cards and one or more answer cards, where each answer card corresponds to one or more question cards, and whereby a student is can associate each question card with an answer card, and learn by confirming the matching of pattern s located on each card to determine if a correct answer has been chosen. The question card may display an illustration sketch or diagram, or express a statement, an incomplete statement, a question or a mathematical expression, or any of these images separately or in combination. The answer card may express the truth or falsehood of a statement of a corresponding question card, a word or sentence fragment which can be used in combination with an incomplete statement of a corresponding question card to complete a statement, a statement that comprises a correct answer to a question of a corresponding question card and/or a mathematical expression or value that comprises a correct answer to a mathematical expression of a question card. The patterns may be located close to an edge of the answer or question card. The pattern may represent a number expressed in base two, or ten or any base of a whole number.
