Pupils may not see the connection between the common divisions of 1,000, 100, 10 and 1 and they may not see the multiplication sign representing the word of when reading the equations.

Allow pupils time to explore the representations of the divisions of 1,000, 100, 10 and 1 alongside each other. Encourage the equations to be read using multiplied by and also of which is more commonly used with fractions of amounts.

Encourage pupils to look for the common divisions of 1,000, 100, 10 and 1 in different contexts and on different measuring scales and identifying the unmarked divisions, making the link to the common divisions in the lesson and linking them to fractions. Stress the language of one-half of.
