This is a brand new category for Year 6 children, emphasising solving problems using ratios. Year 6 Ratio and Proportion Programme of Study Pupils should be taught to: •    solve problems involving the relative sizes of two quantities where missing values can be found by using integer multiplication and division facts •    solve problems involving the calculation of percentages (e.g. of measures) such as 15% of 360 and the use of percentages for comparison •    solve problems involving similar shapes where the scale factor is known or can be found •    solve problems involving unequal sharing and grouping using knowledge of fractions and multiples. What’s new and comments Whilst this is a new category, much of the work was in the old Programme of Study, such as calculating percentages and ratio, previously in the Number category. It is suggested that children solve problems using unequal quantities (e.g. ‘for every two eggs you need 3 spoonfuls of flour).
