So I created the above series of photos for my granddaughter, let her work independently, and this is what happened...
In addition,consider using a series of photos directly on your I-Pad that the students would view step-by-step and create their own shape OR have them create another 3-D shape and take photographs of each step as they create the 3-D shape.
For older students, they could add written directions for each step. This would be an authentic writing assignment.
Have fun... Ella and I certainly did!
