This activity can be done whole-class (on a projector/easel), a tabletop center (displayed as a printed photo/on a tablet), or as an individual journaling activity. My Ontario Kindergarten class enjoys doing these activities orally. We do it completely orally - with no written component at this stage.
This is an open activity. There can be many answers for every set. Stress should be on the explanation of why an object was chosen – not which one was chosen.
