Lesson details
Key learning points
- We can easily calculate multiples of a number by adding on or subtracting that number from an adjacent multiple.
- Multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
- A factor can be partitioned to solve multiplication problems efficiently.
Keywords
Multiples - The product of a number and an integer.
Partition - The act of splitting an object or value down into smaller parts.
Distributive law - The distributive law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
Adjacent - Next to each other. In this lesson, it’s used to refer to multiples that are next to one another.
Common misconception
Counters are being used for unitisation in this lesson but sometimes pupils can struggle to understand that counters can be worth different amounts without a proportional change in size.
Count up and down in different amounts using the counters so that children understand they represent a unit that can have different values in different examples.
