Students love playing games in the classroom and this set will give them the opportunity to practice finding simple interest. Set includes 4 different sets of dominoes: 8 Dominoes, 12 Dominoes, 16 Dominoes and 24 Dominoes. The smaller sets are great for pairs or even a student who likes to work alone. The larger sets are good for groups of 3 or 4. Students cut out the dominoes, turn face down and mix up the pile. Then each student draws the dominoes into their hand. The student with the "start" plays this domino first. Then whichever student has the solution/problem that matches the played domino plays. This continues until one student is out of dominoes and is declared the winner. I usually give 5 points per domino left in other students hands and keep a running tally. Each month we see who the Domino Masters are!
