The cards are mixed up and spread out face down in a playing area. If the two cards do match, the student keeps the pair, and turns over two more cards. If the cards do not match, the play passes to the next student. Play continues until all matches have been made. Working in pairs, one student could quickly show a card to his partner, who in turn would identify the number of items represented on each card.
More advanced students can perform arithmetic drills using the cards.
For example, pairs of students could write out addition or subtraction exercises on the cards and draw representations of the answers. Inc. Created for Sanford. May be freely reproduced for educational purposes.
