Addition, Subtraction, Multiplication and Division - Multiply 4-digits by 1-digit (Pictorial representations) - Presentation

In a mathematics lesson focused on multiplication, students are introduced to the concept of multiplying a four-digit number by a single digit. The lesson builds on the previous knowledge of multiplying three-digit numbers by one digit, asking students to consider whether the process will be similar. The teaching slides facilitate discussion and provide visual aids in the form of pictorial representations. These representations help students understand the value of each digit in a number, using a grid that separates thousands (TH), hundreds (H), tens (T), and ones (O). The lesson emphasizes the importance of setting out calculations in columns to maintain accuracy and ease in understanding the multiplication process.

Students are guided through various activities where they must complete the multiplication of four-digit numbers by a single digit. The activities stress the column method of multiplication, ensuring that students align the digits correctly according to place value. The lesson includes practical exercises where students are asked to complete calculations, such as multiplying 2014 by 3 and finding the product. They also address common errors, such as failing to exchange when a column adds up to ten or more. The lesson's objective is not only to practice multiplication but also to grasp the reasoning behind the process, reinforcing the understanding of place value and the significance of accurate calculation setup.
