Concept map children (school 2). Note that points, i.e., statements, sorted more often together appear closer to each other, and statements never/rarely sorted together appear widely separated.; Arrows indicate a statement is reallocated by researchers, circles indicate a new cluster is created by researchers as a result of reallocation of statements.; Cluster 1: I sit because I can work/play better that way; Cluster 2: I sit because it is the norm/I sit because I have to; Cluster 3: I sit because I’m tired, I want to relax, I want to rest; Cluster 4: I sit because it is a habit; Cluster 5: I sit because there is nobody to play with; Cluster 6: I sit because seated activities are fun; Cluster 7: I sit because of the weather; Cluster 8: I sit because being active takes a lot of effort.
