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.
In Cycle B, a game of bingo is introduced. This allows for deliberate practice of the strategies included in the lesson. Consider how this activity may be best carried out in your class.
