10th workshop: Set theory

Opening circle (10 min)

Big circle: How do you feel now, what happened to you during the last week? 

2. Where do you stand? (10 min)

The facilitator uses ropes or chalk to make three circles next to each other with a diameter of approximately 1,5 metres. Pointing at one of the circles, the facilitator says: Stand in this circle if you like chocolate! The participants decide if they should stand in the circle. Then the facilitator says: Stand in this circle if you know how to make cake! If one of the participants standing in the first circle decide to step in the second circle, the facilitator should ask: So, you don’t like chocolate anymore?

The participants should figure out how to be in two, or even three circles at the same time. When they realize that they have to move the circles so that they have intersecting areas, the facilitator can make further conditions that are varied enough and everybody can relate to at least one or two. E.g. Stand in this circle if you have ever visited the capital, sat on a horse, found an edible mushroom, etc.

3. Sets (12 min)

Participants work in groups of three. Each group gets the picture in Annex 1. The participants have to find three definitions for the three sets similar to those in the first exercise and write themselves in the appropriate place on the picture. The definitions must be made in a way that all the three participants of the group find their place (e.g. those with brown eyes, those who like Maths, those who like spinach).

4. Timetable (12 min) 

Participants work in groups. Their task is to organize online schooling for the number of children they see in Annex 2. The children can share the smart phones and the computers, but they only have as many as there are in Annex 2. The same limitation applies to the access to the internet (shown by the wifi icon). The groups must work out a timetable for the children that includes everybody, but they should also consider that teachers are overburdened and the number of online classes should be kept to a minimum.

In the first round they have to organize language classes: 6 children study English, 4 study German.

In the second round they have to organize separate PE lessons for girls and boys.

In the third round they have to organize Mathematics lessons: 2 students study at advanced level, 5 students study at basic level, 3 students need remedial classes.

5. Where should it go? (10 min)

Participants work in groups. They have to sort the word cards in Annex 3 into three sets by applying any kind of rule or common denominator they can come up with.

6. Closing circle (5 min)
