So let me tell you how we used this awesome app!
First, we went on a shape hunt to take pictures of 2-D and 3-D shapes around the school. My students are very familiar with using the camera on the iPads so this did not take us long. With the help of my student teacher, I took a small group of 4-5 students out of the classroom for about 15 minutes so we were finished taking pictures in one day.
Once the children explored and were comfortable with the app (which doesn't take long for these 5 and 6 year olds) I had them each create their own 2-D/ 3-D shapes slideshow using the pictures they took the previous day! My goal was for them to name each shape as they went through their pictures. I did not require them to tell me if it was 2-D or 3-D and I did not have them specify the number of angles/corners. For this project we focused solely on shape identification.
Their finished products were great especially for our first time utilizing this app! Here are two slideshow examples:
