Step 3 Objective
Extend efficient written methods to short multiplication of HTU or UT by U.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
What if pupils find this a barrier?
Use the grid method for both HTU × U and TU × U as this builds on pupils' mental strategies. Encourage pupils to say the numbers to keep a sense of the place value. Develop towards the partitioning method, making sure pupils can see the links with the grid.
For guidance on written multiplication refer to the document 'The National
Numeracy Strategy: Teaching written
calculations – guidance for teachers at Key Stages 1 and 2' (QCA/99/486)
