The two new titles in the Mental Maths series for children aged between 5 & 7 complement the four existing titles for children aged between 7 & 11. Each book features extensive practice for addition & subtraction; the second book progresses to multiplication & division. These books fill the gaps in our current very popular Mental Maths series providing first-class educational materials for parents to use with their children at home. These books provide a clear approach to number work for parents to follow with their children.
