Column Subtraction Without Confusion | Primary Maths

Column Subtraction Without Confusion | Primary Maths Welcome back to Mr Lewis Teaches. In this video, I explain column subtraction step by step, focusing on why we exchange as well as how to do it. The lesson begins with a subtraction example that needs no exchanging, then moves on to examples where exchanging is required, so children can see the difference clearly. We cover: • Keeping digits in the correct place value columns • Subtracting ones, tens, and hundreds in order • Why exchanging is needed • How one ten becomes ten ones • How one hundred becomes ten tens • A pause-and-try activity with a full check This video is ideal for: • Primary aged pupils • Building confidence with written subtraction • Understanding exchanging through place value • Parents supporting maths homework at home If this video helped, please like, subscribe to Mr Lewis Teaches, and turn on notifications so you don’t miss future calm, clear primary maths lessons.
