Type of Activity: Problem-Solving
Props: 28 Dominoes
Process: There are a couple of games/initiatives you can play with these dominoes.
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.
There are 28 dominoes in a full set: Give a piece to 28 people and they will always be able to link with the rest of the group. Everyone can also link in a circle. (Doubles may need to insert themselves between people who have already linked.)
Remove all the doubles (21 pieces): Give the 21 pieces to 21 people and they will always be able to link with the rest of the group.
Remove the doubles and 6's (15 pieces): The dominoes will link and always leave 2 pieces unlinked; also the end numbers will always read 0,1,2,3,4,5. The two unlinked people could be the "volunteers" for the next event.
Remove the doubles, 6's, & 5's (10 pieces): Give the 10 pieces to 10 people and they will always be able to link with the rest of the group.
Onimod Divisions: To divide a single group into smaller groups: Give each person a domino and ask them to look at the highest number on their piece.
- All the 6’s, 5’s, and blanks together 14
- All the 4’s, 3’s, 2’s, and 1’s together 14
- All the 4’s and 3’s together 9
- All the 6’s and 1’s together 9
- All the 5’s, 2’s, and blanks together 10
- All the 6’s together 7
- All the 4’s and 1’s together 7
- All the 5’s and blanks together 7
- All the 3’s and 2’s together 7
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.
