Step 3 Objective

Extend efficient written methods to short multiplication of HTU or UT by U.


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
