The two new titles in the Mental Maths series, for children aged between 5 and 7, complement the four existing titles for children aged between 7 and 11. Each book features extensive practice for addition and subtraction; the second book progresses to multiplication and 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.
