New Maths Curriculum (2014): Year 5 objectives.
Pupils extend counting from Year 4, using decimals and fractions including bridging zero, for example on a number line.
They should add and subtract decimals including a mix of whole numbers and decimals, decimals with different numbers of decimal places, and complements of 1 (e.g. 0.83 + 0.17 = 1).
They should mentally add and subtract tenths, and one-digit whole numbers and tenths.
Pupils should say, read and write decimal fractions and related tenths, hundredths and thousandths accurately and be confident in checking the reasonableness of their answers to problems.
Pupils should go beyond the measurement and money models of decimals, for example by solving puzzles involving decimals.
