There’s a particular kind of dread that settles over a household on maths homework night. You know the one. The sighing. The pencil tapping. The “I don’t get it” said in a tone that somehow manages to sound both defeated and accusatory, as though the maths itself has personally wronged your child. Maybe there are tears. Maybe there are tears from you too, quietly, in the kitchen, wondering why a worksheet about fractions has turned into a full-blown emotional event.
