These 3D Perimeter and Area Animals are a great way to assess student knowledge while giving them a chance to make choices and use their creativity in math class. My students had a great time with this activity and I was able to make sure that everyone held deep understanding and was able to put it into practice and then write about it in their math journals. We were very happy with the finished products! Click here to see more photos and our procedure: Perimeter and Area 3D Animals for the Classroom
