These are pairing/grouping cards that I use in my classroom to randomly choose new partners for the students. Each student is given a card and then they have to go around and find their “other half”. That process is for partner work.
If you want to form a group of four, each pair matches another pair in some sense. There are 18 pairs and 9 groups of four. There are two sets of pairs/groups. One is the name written out and the other is a picture.
