Shape properties is a kindergarten math skill aligned to Common Core standard K.G.B.4: analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts and other attributes. Below are 8 practice questions with answers and step-by-step explanations, drawn from the 27 shape properties problems our math games drill.
