Year 5 mathematics: written multiplication

Here we have a second page questions that an intermediate step in the progress in the development of an efficient, standard written method of multiplication. It assumes a good knowledge of tables before you start.

This method breaks the task in four parts. For example, when multiplying 538 by 4, the four parts are:

1. the multiplication of 500 by 4

2. the multiplication of 30 at 4

3. multiplying 8 by 4.

4. Add the four answers to reach the final answer.

While this is a good method I prefer to work in the reverse order of starting with the units, then the trans-European networks and finally the hundreds, although if the child understand what happens it makes little real difference.
