Multiplication and Division - Divide by 10 - Presentation

In the third lesson of a series on multiplication and division, students explore the concept of dividing by 10. The lesson encourages pupils to recall patterns observed in previous lessons on multiplying by 10 and to consider how these patterns might apply to division. Through a series of engaging activities, students are prompted to discuss and predict the movement of digits on a place value chart when dividing by 10. For instance, they are shown how the digits shift one place to the right, reducing the value of the number by a factor of ten. This visual and interactive approach helps to demystify the process of division by 10, highlighting the inverse relationship between multiplication and division.

Further activities involve using place value charts and dienes blocks to divide numbers by 10, reinforcing the concept that each digit's value becomes ten times smaller. Students are presented with real-life scenarios, such as dividing money between friends, to apply their understanding in a practical context. The lesson also includes reasoning exercises where students must use clues to solve problems related to division by 10. For example, they are tasked with determining vest numbers for children in a race based on given clues about the relationship between their numbers. By the end of the lesson, students are expected to independently solve calculations and explain their reasoning, solidifying their comprehension of how dividing by 10 affects the value of digits within a number.
