Multiplying 2-Digits by 1-Digit - PowerPoint

Year 3 students are introduced to the concept of multiplying a 2-digit number by a 1-digit number with exchanges through a set of engaging Maths Teaching Resources. The objective of the lesson is to practice and master this mathematical operation using base 10 calculations. Students are presented with a series of multiplication questions where they must apply their understanding of place value to solve problems. For example, in the calculation 16 x 2, the process is demonstrated by breaking down the tens and ones before combining them to reach the correct answer of 32. This methodical approach helps students grasp the concept of carrying over, or 'exchanging', when the product of the ones exceeds 9.

Further reinforcing the lesson, students are given real-world scenarios to contextualize their learning. One such example involves Mrs Brown purchasing boxes of crisps and calculating the total number of packets she has, while another scenario has Pip filling boxes with books and determining the total count. These practical applications of multiplication aim to solidify the students' understanding. Additionally, the resources address common mistakes made during calculations, such as incorrect exchanges, providing students with the opportunity to learn from errors and understand the importance of accurate place value positioning. The exercises include a variety of multiplication problems, some of which require students to deduce the correct numbers to complete the calculations, thereby enhancing their problem-solving skills.
