This jumbo foam domino set is a great problem solver and group mixer.
Onimod Mixer: Ask everyone to meet and greet everyone else who has one of the same numbers on their domino. For example, if I have the 4-3, I'll network with everyone with a 4 and everyone with a 3 on their domino. Everyone will meet 10 others if you eliminate the doubles and have 21 people.
Onimod Links: A link in dominoes occurs when two pieces have the same number of dots on an end. For example a 6-4 and a 4-2 link because they share the number 4. You match the ends together to start a line of domino pieces. The activities below use the concept of linking to get into a line or a circle next to someone you can introduce yourself to. The Onimod Links can take some time to solve unless a leader or coordinator emerges from the group. Onimod Pairs: If you count all the dots on each piece and line them up in numerical order, you will end up with a bell-shaped curve if you graph the frequency of the numbers.
Notice too that you can pair people by simply asking them to partner with someone so the sum of their dots equals 12. You will end up with 14 pairs of people if you start with 28 people. If you have fewer people, just remove pairs of dominoes that add up to 12 until you have left the number of pieces you need.

Onimod Debrief: Give each person a domino and ask them to go and connect with someone else that has at least one similar number on their domino. Then, as the teacher/facilitator, ask a processing question. i.e. How do you think the group communicated during the activity? Or Discuss with your partner ways the group worked well together to complete the task. In this activity, everyone gets to answer the processing questions as opposed to 1 person talking while everyone else listens.
28 dominoes in all, mesh stuff sack, and directions included.
