I highly recommend the following books to use with your Shape Shifters. Read the stories in parts without sharing the illustrations, asking children to use their Shifters to represent story elements each time that you pause. Each time they can share their ideas by doing a gallery walk. To bring in the math, students should look at what they made with a geometric lens: shape, symmetry, pattern, angles, and lines.
