ABSTRACT

Alternatively, and especially for tackling the multiples of 7, 8 and 9, it may be better to use:

• strips of coloured card cut to various whole centimetre lengths – or use the resource sheet provided in activity 8, ‘Ten is greater than one’. Alternatively, Cuisenaire rods are ideal, as they are already cut to different lengths

• a metre rule, or a number line that is measured in centimetres.
