Differentiated Instruction: One Size Does Not Fit All

I teach students soon to be elementary and special education teachers, and they are often surprised to discover that their students are not “one size fits all”. The phrase has been around for decades and originally implied that a particular piece of clothing would fit everybody. Now, in my experience, the one size fits all scarf works for pretty much everyone, not so much for the one size fits all pair of pants or leggings.
