Some favorite comments from 2nd graders as they internalize what algorithms are - “it’s like our bodies have algorithms when we move around” - “it’s like if you were helping a blind person know where to go.” #csinsf@CesarChavezSF⁩ ⁦@SFUSDdot

So, if an improper fraction is not an acceptable term anymore...what do you call it? I have been using a fraction greater than one and I don't what others use. Ideas?
