Long multiplication worksheet

A comprehensive long multiplication worksheet has been outlined for KS2 students, aimed at enhancing their proficiency in multiplying multi-digit numbers by single and two-digit numbers using the formal written method. ©KS2Gems 2022 presents a series of activities that not only teach the mathematical technique but also encourage peer review and critical thinking.

The first activity requires students to use randomly generated four-digit and one or two-digit numbers, whiteboards, and pens. They select digit cards from two piles and perform long multiplication. Peers then verify the accuracy of each other's work, promoting collaborative learning. In the second activity, students are provided with a mix of pre-prepared correct and incorrect calculations. They must identify errors, correct the calculations, and explain the mistakes, fostering analytical skills. The third activity challenges students with missing number puzzles, where they deduce missing digits using given clues and articulate their reasoning process. An example provided is multiplying four consecutive digits by 6 to achieve an answer with matching second and fourth digits. The final activity involves arranging 1-9 digit cards in a grid to achieve calculations that meet various criteria, such as largest or smallest product, and even or odd answers, or answers within a certain range. This activity aims to deepen understanding of number properties and the effects of multiplication.
