Long Multiplication Explained Clearly | Primary Maths

Welcome back to Mr Lewis Teaches. In this video, I explain long multiplication step by step, showing how it links directly to the grid method. Using the example 23 × 31, we explore what stays the same and what changes when the grid method is written in a more compact, vertical form. This lesson focuses on understanding place value, not memorising steps, and helps children see that long multiplication uses the same calculations they already know. We cover: • How long multiplication links to the grid method • Multiplying by ones and tens using place value • Why digits are written in different positions • What stays the same and what looks different • A “try it yourself” example with full checking Perfect for: • Primary pupils learning long multiplication • Parents supporting maths at home • Building confidence with written methods If this video helped, please like, subscribe to Mr Lewis Teaches, and turn on notifications.
