Why this why now
This unit builds on knowledge and understanding of multiplication, including multiplying and dividing by 10 and multiples of 10 to introduce the representation of short multiplication. Pupils apply their understanding of informal strategies based on the distributive law and refine them into short multiplication for 2-digit by 1-digit calculations. This will prepare them for multiplying a 3-digit by a 1-digit number in the next unit.
Prior knowledge requirements
- Recall number facts and sequences
- Use place value understanding
- Apply basic operations in context
