My parents made me do this at the kitchen table.
After sport, or after dinner, they would sit me down with a few times tables on scrap paper. Ten minutes, maybe twenty. I hated it. My mates were on Minecraft.
I was an average student in primary school, sitting in the middle and below-average bands for Maths and English. That scrap paper is the only thing I can point to that changed it.
Later I spent five years tutoring, most of it through a school service program for disadvantaged kids, a lot of them first and second generation immigrants. I watched the same thing from the other side. One session a week never built the habit. Short, repeated practice did.
WorksheetWizard is that scrap paper, with the questions already written for you.
Short practice, done often enough, is what got me that result. WorksheetWizard instils those same habits in the primary school years.
