Help your student become a(n) Shape Recognizer—All Rectangles

Activities include exploring and discussing many shapes of rectangles, all at various orientations, including both typical ones but also "long and skinny ones" and even…squares as "special rectangles" that happen to have all our sides the same length. Discuss that the defining attribute of rectangles are right angles (rect-angles!).
