New Maths Curriculum (2014): Year 3 objectives.
Pupils should connect tenths to place value and decimal measures, not restricted to decimals between 0 and 1 inclusive and to division by 10.
They should begin to understand unit and non-unit fractions as numbers on the number line, and deduce relations between them, such as size and equivalence. They should go beyond the [0, 1] interval, and 1/4 + 3/4 = 1 for example, relating this to measure.
Pupils should understand the relation between unit fractions as operators and division by integers.
They should continue to recognise fractions in the context of parts of a whole, numbers, measurements, a shape, or unit fractions as a division of a quantity.
Pupils should practise adding and subtracting fractions with the same denominator through a variety of increasingly complex problems to improve fluency.
