This is a "wrap around" game, also known as an "I have . . Who has?" game, that I use with my students to review algebra concpets.
There are 30 cards. We display the cards on our interactive whiteboard and have all of my students solve each card. This set can alos be used as an indepdent, partner, or small group activity. The students can put the cards in order to make a long chian of cards.
If there are not exactly 30 kids, some kids cand have partners or some kids can have more than one card.
