Teacher’s Notes on Sum Subtract Product
Pupils use ‘show me boards’ to add, subtract and multiply the
2 numbers which appear.
The pupils could perhaps be in teams and the first pupil to
correctly answer the question scores a point for their team.
It is a good idea for the pupils to draw in the lines along with
the 3 headings at the start. (See below)
