Lesson details
Key learning points
- Calculate the partial products.
- Add the partial products to recombine.
- Regroup when numbers bridge 10 or 100
Keywords
Partial product - Any of the multiplication results we get leading up to an overall multiplication result is a partial product.
Regroup - The process of unitising and exchanging between place values is known as regrouping.
Common misconception
Pupils forget to include regrouped values when multiplying.
Decide on a place and structure for regrouped values - they are included at the top of the algorithm in these lessons to avoid confusion with addition regrouping when partial products are summed. Ensure this is clearly modelled.
