Why is a Square a Rectangle?
Why is a square a rectangle? Formally, a square has all the properties of a rectangle; but how could you explain it to a child in a convincing way?
Here is a design inspired by classroom teachers: Starting from a rectangle, we could create infinitely many rectangles, ..., arriving, at some point, at a square. Therefore, a square is a type of rectangle. So, in a real sense, a square is a stop in a dynamic progression of rectangles.
Two versions are included. The inner square is both 50mm by 50mm. Version A can be smoothly separated; version B has a built-in groove and provides some resistance but can also be taken apart and reassembled. Have fun playing with math!

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.
When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides: http://www.nsta.org/safety/.
