Multiplication and Division (1) - Divide by 10, 100 and 1,000 - Presentation

In the educational resource provided, Lesson 13 is dedicated to enhancing students' skills in dividing numbers by 10, 100, and 1,000. The lesson begins with a discussion inviting students to consider how their existing knowledge of division by 10 and 100 can be extended to dividing by 1,000. This exploration sets the stage for a series of activities designed to deepen their understanding of place value and the effects of division on digits. Students are presented with a place value grid and prompted to observe the movement of counters, representing digits, as they divide numbers by these factors. They learn that dividing by these multiples of ten causes the digits to shift to the right, with the number of moved columns corresponding to the divisor's number of zeros.

Subsequent activities provide practical examples, such as dividing 460 by 10, 5,300 by 100, and 62,000 by 1,000, to reinforce the concept. Students are challenged to apply this knowledge to larger numbers and to explore the relationship between dividing and multiplying by 10, 100, and 1,000. The lesson also includes reasoning tasks that contextualise the mathematical operations in real-life scenarios, such as calculating the remaining money after a bank withdrawal and purchase. Towards the end of the lesson, students are encouraged to create their own problems based on given answers and to use comparison symbols to demonstrate their understanding of the inverse relationship between multiplication and division by these factors.
