5th graders invited us to a wonderful trip around the Earth´s natural regions. We went to the desert, the rainforest, the tundra and some more. In all of them we saw geometric animals that live in those places. Along with parents, we played with conceptual maps made by the students. It was a wonderful and interactive PBL in which we learnt a lot. Thank you 5th graders! We are so proud of you, and of your teachers!
