Multiplication and Division (1) - Multiples of 10, 100 and 1,000 - Presentation

In a comprehensive lesson on Multiplication and Division, students delve into the concept of multiples of 10, 100, and 1,000. The lesson is structured to help students utilise their understanding of multiplication and division by these numbers to explore and identify multiples. They are encouraged to discuss and define what a multiple is and to learn how to recognise multiples of 10, 100, and 1,000. The lesson includes a series of activities where students apply their knowledge to solve related calculations. For instance, they are shown how to use the fact that 36 multiplied by 5 equals 180 to solve similar problems with multiples of 10, such as 36 multiplied by 50 or 500 multiplied by 36.

Further activities guide students through breaking down multiplication problems into smaller, more manageable steps. For example, when multiplying by 20, the problem can be split into two stages, which helps to simplify the calculation process. Students are shown two different methods to solve 24 multiplied by 20, and they discuss the similarities and differences between these methods. Additionally, the lesson covers how multiplication and division can be used inversely to solve problems, exemplified by using a division diagram to find the result of dividing 7,200 by 200. Through independent work and reasoned discussion, students further solidify their understanding of multiples and the relationship between multiplication and division.
