Common misconception
Pupils may start talking of 'adding a zero' to multiply by 10
Don't dismiss this as it is disguising an understanding of a pattern but reassure the pupils that this will be explained later through place value discussions in the coming lessons.
Use countable objects here. Physical resources support this learning really well to begin with.
