Athens College Grade 3 students constructed prehistoric houses and presented them in an exhibition titled "Once Upon a Time and a Prehistoric Age", at the entrance of the Bodossakeion. The children worked within the framework of the PYP interdisciplinary research unit "Where we are in space and time" and captured everything they learned about the habits, occupations, clothing, diet, and of course the dwellings of prehistoric people in this concluding activity. The result of their effort is very creative! Congratulations to the students and their teachers!
