Gather on carpet in circle, with pictures on floor in front of the students. Lay floor graph or two sorting circles on carpet in center of children. Children will choose groupings but you may need to help them narrow it down. The more ways the children have of looking at and analyzing the information before them the better their learning will be. Each student will then place their picture where they think it is appropriate.
Problem solve as a group any discrepancies that arise.
Discuss what they notice when activity is complete. Honor different students' ideas by resorting the pictures several times. You may wish to keep the headers that are written to put on the wall for the children to refer to and read. If you began with sorting circles, try laying out the pictures on a floor graph or just sort them in straight lines on the carpet. Children need not only the practice thinking about data, but need experience organizing it in different ways.
