+In this blog you can see images of our sketching exercises. We were given three exercises that everyone in the group should sketch. The first exercise is 3x3 image scenario sketches, where the same scenario is skecthed in three variations. The scenario should describe three situations: 
 
-## Frederik
+* A teacher presents X to the class
+* Students are working in a group with X
+* One person interacting with X
+
+The second exercise is two school context sketches. The first sketch is in 2D and the second sketch is in 3D. Both sketches include at least one human and a few simple objects to set the stage. 
 
+The third exercise is hand interactions sketches. The sketch is hand interactions with X where there is a indication of the type of interaction.
