WHO HAS . A set of 24 or more cards are distributed to a class of students - at least one card per student. The student who has a card with a blue parallelogram on it responds. Now you are back at the beginning. They are shuffled and turned over randomly.
First player turns over two cards.
If they are a match, the player keeps the cards and turns over two more cards. If they do not match, both are turned back over and the next student has a turn. Play continues until all the pairs are matched. Player with the most matches is the winner. This activity is a practice of addition and multiplication using estimation and calculator skills.
