All Shapes Matter, Paperback/Sreekanth Chakra

All Shapes Matter is a story about five shapes - triangles, rectangles, squares, octagons and circles. The shapes spend their first day at elementary school learning a lot about each other and having fun. However, during recess, some of the shapes come across a problem they are unable to fix by themselves. The unfamiliar shapes who were initially shunned for being different end up coming to their aid. The shapes learn a valuable lesson that their differences can sometimes be more important than their similarities. They realize that there is value in diversity and that 'All Shapes Matter', no matter how similar or different they are.
