Lesson details

Key learning points

  1. In this lesson, we will be required to explain and demonstrate the process of multiplication and division by 10, 100 and 1000 using different visual representations. This understanding will then enable us to derive facts from known multiplication facts which we can represent and explain. The expectation is that by the end of this lesson we will be confidently able to explain and demonstrate how to multiply and divide by 10, 100 and 1000.
